How to make designs for 3D printing: a complete guide for businesses
3D printing has evolved from a tool for rapid prototyping to a real and scalable manufacturing method for sectors such as automotive, engineering, architecture and medicine. However, to realise its full potential, the process must start with an essential step: 3D design optimised for printing. Designing for 3D printing is not just about creating an aesthetic part, but also about adapting the design to the additive manufacturing process, reducing costs, development times and errors during production. In this article, we explain how to design for 3D printing from a business perspective, what professional tools you can use and how to optimise your parts for maximum technical and economic performance. What it means to design for 3D printing 3D design for printing is the digital stage of the additive manufacturing process. It involves creating a three-dimensional model using CAD or 3D modelling software, which is then exported to a printer-compatible format (usually .STL or .OBJ). The difference between a traditional design and one designed for 3D printing is that 3D printing is conceived from the outset with layer-by-layer manufacturing in mind, eliminating the limitations of conventional methods (such as injection moulding or machining), and taking advantage of complex geometries, material lightweighting and customisation without cost overruns. Why companies should design with 3D printing in mind More and more companies are redesigning their products and components with DfAM (Design for Additive Manufacturing) criteria. Why? At Additium 3D, we apply this philosophy to every project: design becomes a competitive advantage, not a limitation. How to design 3D parts professionally Designing for 3D printers requires precision, technical knowledge and a different mindset to conventional design. Define the function and requirements of the part Before modelling begins, identify what role the part plays in the product or system. This information defines the material, technology and tolerances for the design. 2. Choose the right technology Not all 3D printing technologies behave the same, and each has different dimensional limitations, tolerances and resolutions: Designing without taking into account the chosen technology can lead to structural failures or printing cost overruns. Each technology has a minimum recommended thickness: Avoiding walls that are too thin or details smaller than the laser dot size ensures accurate printing and resistant parts. 4. Design to reduce material and time Optimising material is essential to improve economic performance. With smart design you can: At Additium 3D, these optimisations have reduced manufacturing times by as much as 70 % and total costs by 50 % on some industrial projects. 5. Add tolerances and adjustments On parts that need to fit, it is recommended to leave 0.2 - 0.5 mm clearance, depending on the type of material and printer. CAD tools allow you to simulate assemblies and detect interferences before manufacturing, avoiding repetitions or rework. Professional 3D printer design software In business environments, the choice of 3D design software is key to ensuring accuracy and compatibility. These are the most commonly used tools: Designing 3D models for resin printing When the priority is precision and detail, resin 3D printing (SLA, DLP or LFS) is the most suitable technology. Design considerations: 3D models for resin printing are common in jewellery, dentistry, medical devices and high-end industrial design. Optimised design = cost-effective manufacturing A properly designed part designed for 3D printing not only prints better, but also reduces post-processing costs, improves durability and speeds functional validation. Some benefits we see every day at Additium 3D: In other words: intelligent design multiplies the efficiency of the entire production process.

Complete guide to Powder Bed Fusion (PBF) 3D printing
In recent years, powder bed fusion (PBF) 3D printing has established itself as one of the most revolutionary technologies in additive manufacturing. Unlike other more limited 3D printing methods, PBF offers unprecedented design freedom, allows the production of functional parts with geometries impossible to manufacture by injection moulding or machining, and has opened up a new horizon for sectors such as automotive, aeronautics, medical or industrial. At Additium 3D we see it every day: where there were limitations before, today there are real opportunities to manufacture faster, more accurately and without moulds. What is powder bed fusion (PBF)? Powder Bed Fusion (PBF) is an additive manufacturing technology in which a very thin layer of powdered material (typically polymers, metals or composites) is deposited on a printing platform. A laser or thermal energy source then selectively melts the powder in the areas corresponding to the 3D design. Layer by layer, the process is repeated until a solid, precise and fully functional part is created. Once the print is complete, the unfused powder is removed and can be reused in future prints, making the process efficient and sustainable. What is powder bed fusion 3D printing? When we talk about powder bed fusion 3D printing, we refer to a set of technologies that share the same principle: using heat or laser energy to fuse fine powder particles to form a solid part. Among the best known are SLS (Selective Laser Sintering), SLM (Selective Laser Melting) and MJF (Multi Jet Fusion), all of which are applicable depending on the type of material or precision required. This type of 3D printing stands out because it does not require additional supports - the powder itself acts as a support during manufacturing - allowing complex shapes, internal cavities, lightweight structures and articulated assemblies to be produced in a single print. How the PBF process works, step-by-step The magic of PBF 3D printing is in its method: a process that is as precise as it is innovative. Let's take a step-by-step look at how powder bed fusion works and why it is making a difference in industrial manufacturing. The result is high-precision parts with tight tolerances and mechanical properties comparable - and even superior - to those obtained by traditional methods. Common types of PBF technologies Depending on the material and application, there are different variants of the PBF process. SLS (Selective Laser Sintering) Uses a high-power laser to sinter (partially fuse) polymer particles, such as nylon (PA12 or PA11). It is ideal for functional parts, tooling, prototypes or short series, and offers high strength and dimensional stability. At Additium 3D we use this technology to produce hundreds of parts every day, optimising manufacturing times and costs. SLM (Selective Laser Melting) This variant is used with metals (stainless steel, titanium, aluminium, cobalt-chrome, etc.). The laser melts the metal powder completely, creating dense, resistant and high-precision parts. It is a common solution in sectors such as aeronautics, automotive and medicine. MJF (Multi Jet Fusion) Developed by HP, it uses fusion agents and thermal energy instead of lasers. It offers more uniform finishes, high speed and precision, and is perfect for mass production and complex geometries. At Additium 3D we also work with MJF for projects that require high volume production and short lead times. Advantages of powder bed fusion 3D printing Real applications: how PBF is revolutionising manufacturing At Additium 3D we apply this technology on a daily basis in multiple sectors, with measurable and real results: Automotive We manufacture ducts, supports, housings, tooling and functional parts with millimetric precision. Example: a company in this sector needed a tooling that would take 3 weeks with injection moulding; with PBF we deliver it in 3 days, reducing start-up times by 70 %. Aeronautics We create lightweight, optimised components that reduce the overall weight of aircraft. Thanks to design for additive manufacturing (DfAM), we eliminate joints and improve structural efficiency. Medicine We design and produce customised anatomical supports and parts certified for skin contact. Real example: a flexible and adaptable support for catheters, with a perfect finish and high durability. Engineering and architecture We produce accurate mock-ups and structural models, allowing us to validate projects before construction or production. What is needed for fusion to take place? For the PBF process to be successful, three essential elements are needed: What type of 3D printing technology uses a laser to fuse fine powders? SLS and SLM technologies are those that use high-power lasers to fuse fine powders of material. In the case of SLS, the material is partially sintered (ideal for polymers), while in SLM it is fully melted (for metals). Both offer excellent precision, superior mechanical properties and total design freedom. What kind of printers use powder melt technology? Printers using PBF are equipped with: At Additium 3D we use SLS and MJF technology industrial printers, capable of manufacturing short and medium series with precision down to 0.1 mm, guaranteeing repeatability and consistent quality. Additium 3D: experts in PBF 3D printing for companies At Additium 3D we have been helping companies in different sectors to reduce costs, times and manufacturing complexity using powder bed fusion (PBF) technologies for years. We don't just print parts: we offer consultancy, optimised design, prototyping and on-demand manufacturing, adapting to every need and volume.

How to reduce manufacturing times and costs with 3D printing, with real examples
Manufacture thousands of parts in the time it takes to quote for a mould or tool If your business depends on the manufacture of parts, tooling or moulds, you know the bottlenecks that cause delays, high costs and lack of flexibility. Every design change, every new production run and every subcontract can lengthen lead times and drive up indirect manufacturing costs. But what if there was a way to reduce manufacturing time and costs without compromising quality? This is where 3D printing and rapid prototyping become strategic allies for any company. With these technologies, you can manufacture in days what would traditionally take weeks, save direct and indirect costs and gain flexibility that seemed impossible before. In this article we explain how to reduce manufacturing costs, how to implement on-demand manufacturing and show real 3D printing use cases so you can see how other companies optimise their processes and gain competitiveness. The bottlenecks of traditional manufacturing Many companies still rely on conventional processes that slow down their production and generate hidden costs. Some of the most common problems include: Example of indirect manufacturing costs Imagine a company that produces customised automotive tooling. For a traditional mould, 3 weeks of manufacturing, intermediate storage and transportation from the supplier are required. During this time, the plant staff waits to assemble the part, generating unproductive working hours and indirect manufacturing costs. And all of this translates into lost money and delays that affect overall productivity. How 3D printing speeds up times and reduces costs 3D printing is not only a cutting-edge technology, but a practical tool that transforms the way companies manufacture. It makes it possible to optimise processes, reduce production times and minimise costs without compromising the quality of the final product. Moreover, by combining 3D printing with rapid prototyping and on-demand manufacturing, it achieves a flexibility that traditional methods cannot offer. One of the biggest problems with traditional manufacturing is time: developing a prototype or tooling can take weeks, and any changes to the design create additional delays. With 3D printing, these timescales are drastically reduced. Thanks to rapid prototyping, functional models can be created in days, allowing companies to validate ideas and adjustments before moving to mass production. In addition, moulds and tooling that used to take weeks to produce can be ready in record time, speeding up the entire industrial process. Best of all, any design changes can be implemented immediately, without stopping production or generating additional costs for re-scheduling subcontracting or modifying moulds. 2. Cost reduction Production costs are not limited to material alone: moulds, tooling, storage, transport and external subcontracting generate significant expenses. 3D printing allows many of these costs to be eliminated from the outset. By producing on-demand, companies only generate the parts they need, reducing stock and warehousing space. In addition, dependence on external suppliers decreases, and the optimisation of materials and processes ensures that every investment translates into real value, avoiding waste and cost overruns. 3. Flexibility and customisation Today's manufacturing demands not only speed and efficiency, but also the ability to adapt to specific customer demands. 3D printing makes it possible to produce cost-effective short runs thanks to on-demand manufacturing, avoiding large investments in mass production. In addition, each part can be customised to the specific needs of the end customer, something that would be costly and time-consuming with traditional methods. In addition, adjustments and modifications can be made immediately, without generating additional costs or delays, offering a much more agile and versatile manufacturing experience. Comparison: traditional manufacturing vs 3D printing Traditional Appearance 3D printing Manufacturing time Weeks Days / hours Start-up costs High (moulds) Low Design changes Slow, costly Fast, flexible Short runs Uneconomical Economical Limited customisation Total Here are some of our real-world case studies by sector 3D printing is already transforming production across multiple industries. Some 3D printing use cases include: Automotive Production of custom tooling and parts for assembly lines. A company in the industry needed tooling that would normally take 3 weeks. With 3D printing and rapid prototyping, Additium delivered it in days, reducing start-up times by 70 %. Aeronautics Optimised lightweight components and functional prototypes. Thanks to 3D printing, designs can be iterated and parts tested without waiting for lengthy machining processes, speeding up the validation of new components and reducing development costs. Architecture and engineering Detailed mock-ups and structural models. Accurate prototypes can be created before going into production, speeding up project validation and enabling more precise design adjustments without wasting time and resources. Medicine A real-life example from Additium 3D demonstrates the potential of this technology in healthcare: design and manufacture of an elastic, adaptable catheter support. The end result is a perfectly finished part, flexible and adaptable to the human anatomy, with skin contact certification. Moreover, production is extremely efficient: 20 complete kits can be created in just 2 prints. This case shows how 3D printing enables the production of customised customised parts, safely, quickly and cost-effectively. Consumer goods Product prototypes, customised packaging and short runs of final parts. Companies can launch test products or limited editions without high initial investment, facilitating experimentation and rapid innovation in the market. Additium 3D: a complete service for businesses What sets Additium 3D apart is that it doesn't just print parts, but offers complete 3D printing consultancy: With this approach, your company doesn't need to invest in machinery or training, and can take advantage of 3D printing to reduce time and costs from the very first project.

How to prepare and submit your STL file for 3D printing in Additium 3D
If you already have your design ready, the next step is to make sure that the file is perfect so we can print it without any problems. Here I explain everything you need to know to prepare and send your STL file to Additium 3D and get the best quality in your printed piece. What is an STL file and why is it essential for 3D printing? The STL file is the standard format we use for 3D printing. This file converts your design into a mesh of triangles that the printer can interpret to produce your part layer by layer. At Additium 3D, we almost always work with STL because it is the most reliable and compatible with our equipment. What should you take into account when preparing your STL file to send it? What if you have the design in another CAD format? How to convert it to STL? If your design is in CAD formats such as STEP, IGES or DWG, you have to export it to STL before sending it. CAD programs usually have the option “Export as STL” or “Save as STL”. If you have doubts with this step, you can also send us the CAD file and we will help you to convert it so that everything is ready to print. Why is it better to send an STL instead of other formats such as OBJ? Although OBJ stores more visual information, what matters for printing is the geometry of the part, and there the STL is the king. At Additium 3D we optimise your STLs so that the print comes out perfect without losing detail. Where can you find resources to review or improve your STL file before sending it? If you want to make sure that the file is perfect, you can use free programs like Meshmixer or Netfabb Basic to fix possible bugs in the mesh. If you prefer, we will check the file before printing and let you know if we detect any problems. How to send the STL file to Additium 3D? You can send us your STL file through our contact form or by email. If the file is very heavy, we can coordinate a file transfer platform such as WeTransfer or Google Drive. When sending, always include: This helps us to give you a quick and accurate quote. Do you want to convert your STL to other formats such as DXF? If you need a 2D drawing or profile for cutting or milling, we can help you convert your STL to DXF with programs like Fusion 360 or AutoCAD. You only have to ask for it when you send us the design. At Additium 3D we take care of every detail of your file so that the printing is a success. We don't just print; we control the whole process so that the final part is exactly as you imagine it. We check the file, optimise the print and accompany you throughout the process. If you have any doubts or are not sure how to prepare your file, ask us without obligation. We are here to make your project a success.
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%.

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.

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.
