Differences between SLM technology and SLS technology: Why choose SLS for industrial manufacturing?
In the world of industrial 3D printing, SLM and SLS are two of the most advanced and widely used technologies. Although their acronyms are similar, their processes, materials and applications have key differences that you should be aware of if you want to make the best decision for your company. In this article I am going to explain to you, clearly and closely, what each technology consists of, what their main differences are, why in Additium 3D we are committed to SLS technology as the ideal option for many industrial applications and why the use of polyamides such as Nylon 12 has made this technique one of the most demanded in industrial sectors. If you want a more technical and detailed overview, you can also take a look at our specialised page on SLS technology, where we explain the whole process. What is SLM technology? SLM (Selective Laser Melting) technology is an additive manufacturing process that uses a powerful laser to completely melt metal powder, creating solid parts with high precision and strength. This technology works with materials such as stainless steel, titanium, aluminium or cobalt-chrome, ideal for sectors that demand high precision, such as aerospace or medical. What is SLS technology? Selective Laser Sintering (SLS) technology is an additive manufacturing process that uses a high-power laser to fuse thermoplastic powder particles, mainly polyamides such as Nylon 12, layer by layer to form a solid part. Unlike other 3D printing technologies, the unfused powder acts as a natural support, allowing complex parts to be printed without the need for additional structures. This, on an industrial level, is a brutal advantage: more efficiency, less wasted material and more design freedom. Who invented SLS technology? SLS technology was developed in the 1980s by Carl Deckard, while he was a student at the University of Texas at Austin. In collaboration with his professor Joe Beaman, they created one of the first working versions of the SLS system and founded the DTM Corporation, which was later acquired by 3D Systems. This invention was a turning point in the history of additive manufacturing, and today it is still one of the most widely used technologies in industrial environments due to its reliability, precision and mechanical quality. Differences between SLS and SLM technology One of the questions we get asked the most at Additium 3D is about SLM and SLS technology. And although their acronyms are similar, they are different technologies in both process and application. Let's take a closer look at them: Main differences between SLM and SLS Appearance SLM Technology SLS Technology Material Metal powder (steel, titanium....) Thermoplastic powder (polyamide) Process Total melting of the metal powder Partial sintering of the polymer Cost High (material and machinery) More accessible and economical Accuracy Very high, micrometric tolerances High, but oriented towards robust and functional parts Safety and environment Requires controlled atmosphere, inert gases Easier and safer handling Typical applications Medical implants, aerospace Functional parts, prototypes and industrial plastic production 1. Type of material used SLS works mainly with polymers, especially polyamides such as Nylon 12. SLM is designed to work with metals such as stainless steel, titanium, aluminium or cobalt-chromium. This already makes a key difference: the end result is not only different in appearance and weight, but also in cost, strength and applications. Physical process In SLS, the laser sinters (partially melts) the powder particles so that they adhere to each other layer by layer. In SLM, the laser completely melts the metal powder, creating a solid part similar to how a metal part is forged. SLS sintering involves less energy than full metal melting in SLM, which means less expensive equipment and more accessible processes for many companies. Cost of production SLS is generally more affordable in terms of operating costs, materials and equipment maintenance. SLM involves higher costs, both in terms of the price of metal powder and the machinery and environmental control required. In addition, metal part preparation and post-processing times are longer in SLM, resulting in a much higher total cost per part. Precision and tolerances SLM offers very tight tolerances and surface finishes ideal for parts requiring high dimensional accuracy, such as medical implants or critical aerospace components. SLS, while also offering high precision, is more suited to functional plastic parts requiring robustness, but not necessarily micrometric tolerances. Safety and working conditions The metal powder used in SLM is more reactive and dangerous to handle. It requires controlled atmospheres with inert gases (such as argon or nitrogen), specific protective equipment and strict safety measures. In SLS, polymers such as Nylon 12 are safer to handle, making the process easier to implement in more flexible environments. Why choose SLS technology for industrial 3D printing? While SLM technology also offers impressive technical features, at Additium 3D we work closely with companies that need to produce robust, durable parts with complex geometries. And this is where SLS technology really shines: In addition, the use of Nylon 12 in SLS offers a unique combination of stiffness, durability and chemical resistance that allows us to produce final parts, not just prototypes. SLS technology and polyamide: the perfect combo One of the most commonly used materials in SLS technology is polyamide, especially Nylon 12, a thermoplastic that stands out for its stiffness, durability and chemical resistance. Nylon 12 allows us to manufacture parts that can be used directly as final components, without compromising functionality or strength. At Additium 3D we have been using SLS technology with polyamide, especially Nylon 12, for years because of its advantages: that's why, when we talk about SLS polyamide technology, we are talking about a professional solution that goes far beyond prototyping. Why trust Additium 3D for your parts?
What is mass production and how has it evolved with 3D printing?
Mass production has been one of the pillars of modern industry since the Second Industrial Revolution. Thanks to this model, companies all over the world have been able to manufacture products in large quantities, reducing costs and standardising processes. Today, with the emergence of new technologies such as 3D printing, mass production is undergoing a new revolution, especially in sectors that demand customised parts or on-demand manufacturing. Definition and concept of mass production Mass production, also known as mass production model or chain production, is a manufacturing system in which large quantities of the same product are produced through repetitive and mechanised processes. What does mass production mean? It implies that products are manufactured in a standardised way, with tasks divided into stations within a mass production line, allowing for greater efficiency and lower unit cost. When did mass production emerge? Mass production became established at the beginning of the 20th century, although its antecedents date back to the Industrial Revolution. The model became popular with Henry Ford and his assembly-line automobile manufacturing system, also known as Fordism. This revolution in industrial production allowed vehicles to be manufactured more quickly and at affordable prices, marking a turning point in the history of the industry. Characteristics of mass production The main characteristics of mass production include the following: This production system makes it possible to manufacture identical products in large quantities, guaranteeing uniform quality and more exhaustive process control. Industrial series production: our experience, advantages and limits At Additium 3D we work on a daily basis with companies that need efficient, scalable and high quality series production. From technical components for industrial sectors to functional parts for end products, we have seen first-hand how mass production is a key tool for scaling up projects and reducing costs. But we also know that it is not a universal solution: it has its pros and cons, and you have to know when to apply it and when not to. Advantages of mass production (from our experience) One of the biggest advantages we see in our work is the economy of scale. For example, when an automotive customer asked us to produce a long series of parts for functional prototypes, we were able to optimise the process thanks to good initial preparation and the use of technical materials in industrial 3D printers. The cost per unit dropped dramatically as the volume increased, making a large-scale testing phase feasible without blowing the budget. In addition, speed is a factor that is highly valued by our customers. In sectors such as product design or architecture, where we have collaborated with studios that needed to iterate versions in a short time, 3D printing allows us to deliver series of parts in a matter of days. This would be unthinkable with traditional industrial processes, which take longer to set up. Another big advantage is consistent quality. By working with advanced technology and composite materials, we can ensure that all parts in the same series maintain the same mechanical and aesthetic properties, which is essential when it comes to functional or display applications. Disadvantages (which we also experience on a daily basis) However, mass production also has its limits, and at Additium 3D we are well aware of them. A clear example is the rigidity of the system: if a client wants to introduce changes once production has started, it is necessary to adjust files, parameters and sometimes even rethink the strategy. This happens a lot in projects where the design is not yet 100% validated. Another important aspect is the initial cost. Although 3D printing avoids expensive moulds and tooling, it does require a technical set-up phase - materials, supports, orientations, validations - which takes time and expertise. We always explain this to our customers before starting series production, because not everything is “print and go”. And finally, although we work with a sustainable mindset, high-volume production can generate waste, especially when substrates are used or parts have to be discarded due to defects. That's why in every project we propose solutions to optimise materials, minimise errors and reduce the environmental footprint. In which sectors is mass production used? In a wide variety of industrial and commercial sectors, especially in those where large volumes of products need to be manufactured efficiently, homogeneously and cost-effectively. Some of the most representative sectors are: 1. Automotive industry This is one of the most emblematic sectors. In fact, mass production as we know it today emerged with Henry Ford and the production of the Ford Model T at the beginning of the 20th century. Since then, the mass production line has been perfected to produce millions of vehicles per year, while maintaining very high quality standards. Electronics and household appliances Mobile phones, computers, televisions, washing machines and microwave ovens are manufactured using mass production processes that enable large quantities of units to be brought to market quickly, reducing costs and time. 3. Food industry From beverages and canned products to snacks and frozen foods, mass production allows processes to be standardised to guarantee food safety, traceability and constant supply in supermarkets and shops. Pharmaceutical industry Medicines and medical devices require highly controlled mass production processes, with very strict quality protocols. Automation makes it possible to comply with health regulations and supply worldwide. Textile and fashion Although there is a handcrafted part in the design, the manufacture of clothing, footwear or accessories is carried out through industrial mass production, especially for large brands and fast fashion chains. 6. Furniture and furnishings Many pieces of furniture are manufactured on automated lines that allow for accurate repeat designs, speedy delivery and competitive prices. 7. Aerospace and defence Aerospace and defence combines mass production with customised manufacturing.
Can spare parts be printed with 3D printing? Examples of spare parts that can be manufactured
In the world of industry and maintenance, waiting weeks for a traditional spare part can be frustrating and costly. This is where 3D printed parts make a difference. Because adding this solution to your workflow allows you to reduce downtime, save on inventory and manufacture customised parts on demand. In this article we show you how to get the most out of this technique for your factory or vehicle. Why use 3D printed parts? 3D printing not only speeds up failure response, it also offers unprecedented flexibility: These benefits translate into lower costs, higher productivity and a more agile production chain, especially relevant when it comes to automotive parts. What parts can be manufactured with 3D printing in the automotive industry? In the automotive sector, 3D printing has become a key ally for the manufacture of spare parts, especially in older models or when quick and customised solutions are needed. It allows functional components, adapters or aesthetic elements to be created with high precision and at low cost, without relying on large print runs or stock. Some examples of spare parts that can be manufactured are: What parts can be manufactured with 3D printing in industry? In the industrial environment, 3D printing opens up a range of possibilities that go far beyond prototypes. It has become a practical and efficient solution for producing functional parts, adapters, specific tooling and even spare parts that are no longer available on the market. Many companies use it to manufacture bespoke components that optimise their internal processes: from a bracket that fits perfectly on a specific machine to a protective housing designed for a specific sensor. The key is that you don't need to rely on large print runs or wait weeks for a part to arrive from the other side of the world. Here, “I need it yesterday” finally finds a viable answer. It is also being used to solve day-to-day contingencies. When a production line stops because a simple but hard-to-replace part breaks, having access to a local 3D printing service can make the difference between losing hours or continuing production without interruption. In sectors such as food, chemicals or energy, customisation and speed of response are essential, and this is where additive manufacturing is consolidating as a strategic resource, not just as something innovative or for the future, but as a real tool that is already helping many companies to be more efficient. Recommended materials for 3D printing parts Choosing the right material is fundamental. Here is a selection of the most useful for spare parts according to their function: Technical plastics Nylon (PA): durable, wear-resistant. Ideal for moving parts (gears, bearings, hinges). ABS: widely used. Resistant to impact and moderate heat: ideal for housings or supports. PETG: combines toughness, chemical resistance and printability. Very versatile. Polypropylene (PP): flexible, excellent for interlocking/bending parts such as caps or clips. TPU/TPE: elastic polyethylene for gaskets, cushions, or flexible parts. High-performance plastics Polycarbonate (PC): high toughness and heat resistance, even semi-transparent. Suitable for automotive or electrical parts. High temperature resins: for environments above 100°C, require professional SLA printers. Mixed polymers (PC-ABS, PA-CF, PET-CF): with special fibres, they offer high mechanical strength, ideal for demanding industrial environments. 3D metals Stainless steel, aluminium, titanium: manufactured by technologies such as DMLS or SLM, they are ideal for critical mechanical parts. Their price is high, but their performance is superior. What type of 3D printing fits what you need? There are several 3D printing technologies, and not all of them serve the same purpose. Here's a quick guide to help you choose the right one for the type of part you need: FDM (Fused Deposition Modelling) It's the cheapest and most accessible. Ideal if you are looking for functional plastic parts without getting too complicated. Of course, the finish has those typical visible layers, although this is often not a problem. SLS (Selective Laser Sintering) Here we are talking about pro level. It doesn't need supports and can withstand anything you throw at it. Very useful when there are rare geometries or you need resistant parts for real use. SLA (Stereolithography) If your thing is small, detailed and with a fine finish, this is the one for you. It really shows in the final result when there are details to mark. MJF (Multi Jet Fusion) A balanced option: good resistance, good speed and perfect if you want to make a small series of parts without losing quality. DMLS/SLM (metal printing) This is a big one. If you need a functional, temperature and pressure resistant metal part, this is the option for you. Mostly used in engineering and demanding sectors. Your part, from scratch: the process explained step by step Step 1 - Check technical requirements Geometry and dimensions The part must fit the build volume of the 3D printer. If it is too large, it can be split and assembled after printing. Environmental conditions Will the part be exposed to heat, chemicals, UV or mechanical stress? The choice of material must meet these requirements. Durability For permanent uses, technical polymers or even metals are recommended. For temporary uses, more economical options may be chosen. Finishing and precision If the part will be visible or must fit perfectly into an assembly, the printing technology and post-processing must be considered. Some technologies require post-processing adjustments or touch-ups to achieve the desired tolerance. Target of use Is it an interim or final solution? This will determine the requirement in terms of materials and print configuration. Step 2 - Modelling or digitising Step 3 - Choice of technology and material Select technology based on strength, finish and budget. Choose the material based on functional and environmental use. In short: You want good results? Optimise these parameters to improve the result: Layer height: For fine resolution, ideally between 0.05% and 0.05%.

In recent years, 3D printing in medicine has become one of the most transformative tools in the healthcare sector. Its ability to create customised devices, tailored to the real needs of patients and professionals, is revolutionising the way healthcare is delivered. In this article, we explore how Additium 3D technology is improving public and private healthcare from its headquarters in Valencia, and analyse real cases that show the potential of this technology to transform healthcare. 3D printing in medicine: from theory to practice Unlike other sectors, where 3D printing is mostly used for rapid prototyping, in healthcare it has a direct impact on people's lives. The use of anatomical models, surgical guides, customised orthoses or functional aids has become an accessible reality thanks to companies like Additium 3D. This Valencian company does not sell printers and is not focused on large industrial runs. Its model is based on customised and local manufacturing, in direct collaboration with medical teams. Each part is designed with a purpose: to solve a specific need. Real clinical applications of 3D printing: Additium 3D success stories A support to improve dialysis in a hospital in Valencia One of the most significant projects has been the manufacture of a small support for patients undergoing dialysis treatment. Designed in close collaboration with the hospital's nursing staff, the aim was to avoid direct contact between the catheters and the skin, reducing the risk of infection and increasing comfort. This part is printed in biocompatible materials and delivered ready for use within hours, allowing for safer and more efficient care. Another touching case is that of Pablo, a young man with a neuromuscular disease who needed a cranial support for his motorised wheelchair. His frame did not provide support for his head, which limited his autonomy. The Additium team scanned his posture and the chair with a 3D scanner, and fabricated a Nylon 12 support using SLS technology, perfectly adapted to his body. Pablo can now use his chair more comfortably, safely and stably. «Very comfortable and safe. And thanks to Additium 3D, it's great,» says Pablo himself. What are the main applications of 3D printing in healthcare? 3D printing in healthcare has many applications. Some of the most relevant include: 1. Personalised medical devices From splints to fixation devices, adapted to the patient's anatomy. They are more effective, comfortable and less invasive. 2. Surgical guides They allow interventions to be planned with greater precision and reduce operating theatre time, which translates into lower risk and better recovery. 3. Anatomical models Ideal for teaching, surgical planning or explaining complex procedures to patients. They are printed on materials that simulate the texture of real tissues. 4. Orthopaedics and functional aids Chairs, supports, adaptations for the home... 3D printing allows for inclusive and affordable, fully customised solutions. Implants and prostheses Still under development, but major advances have already been made in materials that allow more precise and compatible implants. Artificial organs and tissues Although their clinical use is still limited, advances in bioprinting open the door to a future where it is possible to 3D print organs for transplantation or testing. Key benefits of 3D printing in medicine 3D printing in medicine is not only a technological revolution, but also a practical tool with a direct impact on the quality of care. It makes it possible to move from generic solutions to customised solutions, manufactured in record time and with full traceability. For healthcare centres, hospitals and clinics, it represents a strategic advantage: adapting to the patient, streamlining processes and optimising resources. These are some of the most outstanding benefits: Additium 3D: your 3D printing partner for healthcare If you are a hospital purchasing manager, medical area manager or healthcare professional and you think that 3D printing could help you, the Additium 3D team can accompany you throughout the process. From initial design, through material selection and manufacture, to ready-to-use delivery. They work without intermediaries, which guarantees a fast, local and traceable service.
3D printing filaments: types, real-life uses and how to choose the right one
3D printing using FDM (Fused Deposition Modelling) technology has become an essential tool for product development, rapid prototyping, and small-scale manufacturing. One of the most important determinants of success in any project is the choice of the right 3D printing filament. Each type of filament has unique properties that make it more or less suitable for certain uses. In this article, we explain in depth the most common types, their actual applications and give you practical examples to help you decide. PLA (Polylactic Acid) PLA is the most popular filament among beginners and is also widely used in the early stages of product development. Advantages: Disadvantages: Real-life example: A startup designs a new eco-friendly packaging for solid cosmetics. It uses PLA to print the first prototypes and validate design and ergonomics with potential users. They do not yet need functional parts, only aesthetic and presentation parts. ABS (Acrylonitrile Butadiene Butadiene Styrene) Material widely used in automotive and electronics. More complex to print than PLA, but with better technical properties. Advantages: Disadvantages: Real example: An urban mobility company prints the shells of its electric scooter prototypes in ABS, to test resistance to urban use and light impacts before moving on to definitive moulds. PETG (Polyethylene Glycol Terephthalate) PETG is a balance between PLA and ABS: easy to print, but with more technical properties. Advantages: Disadvantages: Real-world example: a startup that manufactures hydroponic growing systems produces joining parts, supports and conduits with PETG to ensure they can withstand water and humidity without degrading. TPU (Thermoplastic Polyurethane) TPU is a flexible filament, ideal for parts that require elasticity or friction resistance. Advantages: Disadvantages: Real-life example: A sports footwear project prints soles and flexible parts with TPU to test ergonomics and grip before launching a final industrial version. Nylon (Polyamide) Technical material par excellence. High mechanical resistance, good flexibility, and withstands high temperatures. Advantages: Disadvantages: Real example: An educational robotics company prints gears and moving parts of robots with Nylon to ensure resistance in the classroom without breakage. 6. Filaments with fillers: wood, carbon fibre, metals These are composite filaments, usually based on PLA or PETG, with additives to improve aesthetics or mechanical properties. Common types: Advantages: Disadvantages: Real-life example: A design studio prints decorative products with wood-filled PLA to show its customers a realistic and sustainable finish, saving costs in the aesthetic validation phase. Choosing the right filament for your 3D printing Choosing the right 3D printing filament is a critical part of any successful development. It's not just about «the part coming out», it's about it making sense in the process: saving costs, avoiding mistakes and anticipating the next step in the product. At Additium 3D, we work with startups and companies to accompany them from the idea to the actual manufacturing, choosing the right materials and technologies for each stage. If you have doubts about which filament to use, or if you need to prototype with technical materials, we can help you.
What is laser cutting and what types are there (CO2, 2D...)?
Laser cutting is a manufacturing technique that allows materials to be cut with incredible precision using a concentrated beam of light. It is used in sectors as varied as architecture, engineering, advertising and product design. Did you know that not all laser cutting is the same? Let's take a look at how this technology works and what types of laser cutting exist, such as CO2 laser cutting or 2D cutting. How does laser cutting work? Laser cutting is based on concentrating a high-intensity beam of light on a very small spot on a material. The heat it generates is so high that it melts, burns or vaporises the material, separating it with clean, precise cuts. All of this is controlled by computer-aided design (CAD) software, allowing parts with very complex shapes or fine details to be made. Types of laser cutting Within the world of laser cutting, there are several types depending on the technology used. The most common are: What is 2D laser cutting? 2D laser cutting is a type of cutting that works in two dimensions, i.e. on a plane. It focuses on defining contours and shapes from a sheet of material, such as a wooden board or a sheet of methacrylate. It is ideal for manufacturing flat parts, posters, templates, prototypes, decorations or models, with great speed and precision. At Additium 3D, for example, we work with 2D CO₂ laser cutting in formats of up to 1400 x 900 mm, offering impeccable finishes in both cutting and engraving. What materials can be cut with CO2 laser? The CO2 laser is extremely versatile and allows us to work with a wide variety of materials. Here are some examples: In addition, CO2 laser cutting also allows the engraving of metals, further opening up the range of possibilities for customising parts. Advantages of laser cutting Why is laser cutting so widely used? Here are some of its main advantages: Applications of laser cutting Laser cutting has applications in countless industries: Whether you need a functional part or a unique decorative element, laser cutting offers a fast, precise and cost-effective solution.
3D printing problems: 7 common mistakes and how to avoid them with a customised service
3D printing has revolutionised the way we design, prototype and manufacture products. But it's also true that it's not a plug & play process. Whether you are just starting out or you have already tried printing with suppliers or your own printers, it is likely that you have encountered some of these 3D printing problems: parts that do not stick to the base, misplaced layers, mistakes with the material or unprofessional finishes. At Additium 3D we hear about these cases every week. That is why we have prepared this guide to common mistakes and problems in 3D printing, with practical solutions and real examples. In addition, we tell you how our personalised service helps you to avoid these mistakes from minute one. Common problems in 3D printing: the most frequent errors and how to solve them We have compiled a list of the most common errors that our customers tell us about. Some are technical, others are design-related, others are process-related. All of them can be solved with the right methodology. 1. Problems with the first layer of 3D printing One of the most frustrating printing errors: the first layer does not adhere well to the base, peels off or is uneven. This failure is the origin of many failed parts. Possible causes: How we solve it: Before printing, we always carry out a professional makeready and calibrate the appropriate parameters according to the material and geometry. In addition, if your design is not optimised for good adhesion, we adapt it. 2. 3D design errors that prevent correct printing Many of the problems in 3D printing are not in the machine... but in the file. Models with too thin walls, open geometries, poorly defined supports or without tolerances. Typical errors: Our approach: We include technical advice and file review before printing. If needed, we redesign or correct models to ensure that the print will be workable and functional. 3. Printing errors with PLA (and other materials) PLA is one of the most widely used materials, but it is not without its problems. Many errors come from incorrect setup or misuse of the material. Most common PLA 3D printing mistakes: What we do differently: At Additium we use high quality materials, with parameters tested and calibrated on our own printers. We also work with PETG, ABS, Nylon, PA12, technical resins... and we help you to choose the most suitable one according to the application. Problems when changing filament in 3D printing Changing filament is another common source of errors: jams, clogged nozzle, mixing of colours/materials, poor adhesion right after the change. Additium solutions: This is key especially in multi-unit productions, where a small mistake can ruin a whole series. Ghosting in 3D printing: wavy or vibrating surfaces Ghosting or ringing occurs when the printer vibrates during fast movements, and an echo effect is generated on the surfaces. How we avoid it: 6. Flow problems in 3D printing Incorrect material flow (over/under extrusion) leads to poorly bonded layers, threads, bubbles or even structural failures. Our method: We check the actual extrusion flow and apply compensations if necessary. In addition, in critical cases we use measurement and simulation techniques to ensure consistency throughout the part. 7. Resin 3D printing errors Resin printing (SLA/DLP) has its own particularities. It is common to see curing errors, poor adhesion or poorly placed supports. Solutions from Additium: And now the 3 most common defects and errors in 3D printing and how to solve them effectively Warping (or how your parts come off the bed and deform) What is warping? Warping is one of the most common and frustrating defects in 3D printing. It occurs when the edges of a printed part start to lift off the bed, causing the base to curve upwards. This not only ruins the visual finish of the part, but can affect its functionality if the final dimensions change. Why does it happen? The main cause is shrinkage of the plastic as it cools. This effect is most pronounced in materials such as ABS or Nylon, which shrink significantly as they go from molten to solid. If the base of the part cools too quickly, it shrinks more than the top layers, causing internal stresses that eventually detach it from the bed. Other aggravating factors: How to avoid it? Cracking or delamination (when the layers separate) What is cracking? Cracking or delamination occurs when the layers of a piece are not properly bonded together. To the naked eye, you will notice horizontal cracks or separation lines between layers. This problem is especially common on tall parts or parts with thin geometries. Why does it happen? There are two main culprits: How to avoid it? Layer shift (when your part looks like it has been pushed) What is layer shift? Layer shift occurs when layers become horizontally misaligned. The part starts out fine, but at a certain point it looks like everything has shifted to one side, as if someone has pushed it while printing. Why does it happen? How to solve it? Troubleshooting 3D printing: what we do at Additium 3D Instead of just printing a file, at Additium 3D we offer a comprehensive service that prevents most errors before they happen. How do we do it? We review the design, analyse its functionality and propose improvements if necessary. We select the most suitable material according to use, resistance, aesthetics and budget. Industrial FDM, resin, composites... with customised calibration and configuration. Sanding, painting, assembly, polishing... So that the result is functional and visually professional. From single prototypes to medium series. Delivery on tight deadlines, with follow-up at every stage. Are you having problems with 3D printing? We know what it's like to fail part after part. Or receiving a «supposedly valid» file that doesn't work. Or not knowing what to do when the material doesn't give the expected result. That's why at Additium3D we don't just print.
Are you an industrial startup? Here's how 3D printing can help you launch your product
In the first steps of an industrial or hardware startup, every decision counts. Validating a design, launching a product batch or even simply testing a concept can involve a very high investment... or not. This is where 3D printing becomes a strategic ally: agile, economical and without moulds. In this post we tell you how to make the most of it if you are setting up a project from scratch or are ready to go from idea to physical product. Why choose 3D printing if you are a startup? Starting a company is already a challenge in itself. But if your project also involves manufacturing a physical product, the risks multiply. 3D printing allows you to reduce them to a minimum. Rapid iteration and total design freedom You can modify your product as many times as you need to without incurring new costs or having to wait for weeks. Ideal for validating prototypes, improving versions or even testing several designs in parallel. 2. On-demand production, without stock Print only what you need, when you need it. This is key for launching small pilot runs, making pre-sales or selling on demand without having to fill a warehouse. 3. No moulds, no barriers to entry Manufacturing with traditional moulds can cost several thousand euros, something totally unfeasible for most startups. With 3D printing, you can produce without moulds from unit 1. 4. Reduced development times Going from design to physical part in just a few days is a huge competitive advantage. It allows you to validate faster, get to market sooner and respond better to changes. 5. Accessible even if you don't have a technical team If you don't have a 3D designer or a product development team, that's OK. At Additium 3D we take care of everything: from design to prototyping to final production. What kind of startups can benefit from this? We have accompanied dozens of industrial and technological startups, and many of them share the same challenge: to transform a good idea into a real product without skyrocketing costs. Here are some profiles that can make the most of 3D manufacturing: They need functional prototypes or even small series to validate their product or deliver it to their first customers. Such as IoT projects, wearables, home automation, mobility... that require manufacturing customised parts for their devices. They have a validated idea or a clear solution, but do not have the resources to design or develop it technically. When a product needs adjustments, 3D printing allows them to do it quickly and affordably, without breaking the budget. Case studies: how other startups are doing it 3D printing manufacturing is no longer just for big companies. More and more startups are using it to validate ideas, launch their first units on the market or adapt quickly to changes. Here are some real examples: Case 1: Electric mobility startup A young micro-mobility company manufactured a customised casing for its electric device using 3D printing. This allowed them to launch a first batch of 100 units without investing in moulds or taking on large financial risks. Case 2: Healthcare startup with no technical team An early-stage startup focused on developing medical solutions needed to validate an ergonomic support for a device. With no designer or development team, they opted to outsource the entire process and use 3D printing to rapidly iterate several versions. Today they are manufacturing on demand while scaling up. Case 3: Home automation startup in MVP phase A smart home technology company tested three different versions of a sensor housing in less than two weeks. It was able to validate the design directly with end users before deciding which to scale, without the need to manufacture tooling or build up stock. The Additium 3D Startups Plan: no risk, no moulds, no hassle We've designed a plan exclusively for startups like yours. Our goal: you can launch your product without the cost of the design or the mould holding you back. The Startups Plan includes: This way you reduce the initial risk to the maximum and you can focus on validating your product, attracting your first customers or closing financing rounds. Ready to manufacture without moulds? We know how difficult it is to start a project from scratch: limited resources, high-impact decisions and a fast-moving market.

3D printing of religious images: a new era for sacred art
3D printing technology has arrived in the world of sacred art to offer new ways of preserving and reproducing religious heritage. Thanks to advances in high-precision scanning and printing, it is now possible to make 3D replicas of religious figures that faithfully maintain all the original details, respecting both their artistic and spiritual value. In this article we will explore how 3D printing of religious images is transforming the conservation, restoration and reproduction of religious pieces throughout Spain and elsewhere in the world. What is 3D printing of religious images? 3D printing of religious images is the process by which physical copies of religious sculptures, figures or symbols are created using additive layering technology. Materials such as resins, plastics, ceramics or even metals are used, depending on the desired finish and strength. This type of printing makes it possible to manufacture customised pieces, make exact reproductions of historical sculptures or even create new figures adapted to contemporary tastes and needs, always respecting the essence of the original work. 3D scanning to preserve heritage forever One of the great revolutions brought about by this technology is 3D scanning to preserve heritage forever. Using high-precision scanners, it is possible to digitise religious figures and objects with an extraordinary level of detail. These digital archives not only make it possible to produce copies, but also to preserve for future generations the visual memory of pieces that would otherwise be exposed to wear and tear, the passage of time or possible damage. Thus, 3D scanning becomes an essential tool for museums, churches, brotherhoods and private collections interested in protecting their legacy. 3D printing of real objects, pieces, figures and religious objects The versatility of this technology makes it possible to tackle a wide variety of projects: from the creation of large 3D replicas of religious figures to the reproduction of small liturgical objects. 3D printing of real objects, pieces, figures and religious objects is particularly useful in restoration processes, where it is often necessary to manufacture parts to replace damaged or lost elements, while respecting the original form. Moreover, as it is a highly customisable process, it is also possible to make adaptations in size, materials or finishes, always under criteria of fidelity and respect for the religious work. Personalised religious figures The possibility of creating personalised religious figures opens up new avenues of expression for both religious institutions and individuals. Thanks to 3D printing, it is now possible to reproduce images of saints, virgins or biblical scenes adjusted to specific sizes, artistic styles or specific needs. This customisation also makes it possible to add unique details, specific facial expressions or to incorporate symbolic elements that reinforce the spiritual connection of each work. Exact replicas of religious sculptures with unprecedented fidelity Traditionally, making copies of religious sculptures was a laborious process and, in many cases, inaccessible to small temples or individuals. 3D printing of religious images has democratised this possibility, making it possible to 3D print identical copies of any size with great fidelity. Every fold of the robe, every facial feature or every small ornament can be replicated with a level of detail that makes the reproductions virtually indistinguishable from the originals. Applications of 3D printing and 3D scanning in sacred art The possibilities offered by this technology in the religious field are manifold: Thanks to 3D scanning to preserve heritage forever, many images that might have disappeared today continue to transmit their beauty and meaning to new generations. An opportunity for art, culture and faith 3D printing of religious images not only facilitates the reproduction of sacred figures and objects, but also opens a door to creativity, preservation and cultural dissemination. In a world where technology is advancing every day, respect and passion for sacred art find in 3D an irreplaceable ally to continue to move and accompany people through time.
Real comparison: Injection moulding or 3D printing, what suits your project?
Injection moulding vs 3D printing: What I learned from working with companies in different industries In recent years, 3D printing has revolutionised the way we design and manufacture parts. However, plastic injection moulding is still a key method in many, many industries. Having worked with companies in fields as diverse as automotive, healthcare, architecture, industrial design and energy, I have seen first-hand how each technology has its place. So in this article, I want to help you understand the differences, advantages and limitations of injection moulding and 3D printing, and most importantly, when to choose one or the other. What is injection moulding? Plastic injection moulding is an industrial process that involves melting a plastic material and pressing it into a metal mould. After cooling, the material solidifies and produces identical serial parts. It is an established technique and widely used in sectors such as automotive, consumer electronics, packaging and medicine. Its great value lies in the mass production of parts with high precision and repeatability. Advantages of injection moulding Injection moulding stands out for its efficiency and ability to produce identical parts in large quantities. Throughout my experience with different industries, I have seen how this technique is indispensable for projects where consistency and unit cost are critical. Disadvantages of injection moulding Although injection moulding is a well-established technique, it is not without its limitations. Understanding these limitations allows you to better plan your projects and avoid unnecessary costs. What is 3D printing? 3D printing, or additive manufacturing, is a process in which a part is built layer by layer from a digital design. There are different technologies (FDM, SLS, SLA, among others) and a wide variety of materials: plastics, resins, metals and even composites. The most interesting thing about 3D printing is its flexibility and capacity for customisation, making it possible to manufacture from prototypes to small series, without the need for moulds or tooling. Advantages of 3D printing 3D printing offers a world of possibilities, especially when you need to experiment with designs, reduce times or customise parts. Throughout my experience working with companies in different industries, I have seen how these advantages can make all the difference in the development phase of a product. Disadvantages of 3D printing Like any technology, 3D printing also has limitations that you should be aware of before deciding how to manufacture a part. Identifying these disadvantages from the outset avoids unnecessary delays and costs. Tip: When to choose injection moulding or 3D printing? The choice between injection moulding and 3D printing depends on several factors such as production volume, part complexity and time available. Here are some case studies to help you decide which method to use. Cases in which it is advisable to choose injection moulding Cases in which it is advisable to choose 3D printing 3D printing stands out for its flexibility and speed, especially in development phases or when single parts are required: Injection moulding vs. 3D Printing: Quick comparison Feature Plastic injection moulding 3D printing Production volume High (thousands-millions) Low-medium (one unit to thousands) Initial cost Very high (moulds) Very low Cost per part Very low in high volumes Medium-high Design flexibility Low Very high Initial development time High (mould making) Very low Materials available Wide variety of plastics Wide and growing Complex geometries Limited Very easy Speed in mass production Very high Low In short, when to choose one or the other? In reality, many companies combine both technologies: they use 3D printing for prototyping and validation, and once the final product is defined, they move to injection moulding for mass production. The balance between the two technologies: find out which is best for your project There is no universally “best” method. It all depends on your project, your budget, the volume you need and the development timeframe. The important thing is to understand that both injection moulding and 3D printing are complementary, and when used well, they can reduce costs, speed up time-to-market and improve the quality of the final product. At Additium 3D we have accompanied companies from different sectors in this decision-making process, advising them according to their specific needs.
