5 3D printing myths holding the industry back (and why they no longer make sense)
For years, 3D printing has lived in a kind of industrial limbo. Admired for its rapid prototyping capabilities, but questioned when it comes to actual production. However, while many companies still see additive manufacturing as a laboratory tool, the global market exceeds $20 billion and its industrialisation is no longer a future promise, but an established reality. So why are only a fraction of companies using 3D printing for final parts? The answer is not in the technology. It is in the myths. Myth 1: “3D printing is too expensive for mass production” This myth stems from a simplistic comparison: price per part vs. price per part. When comparing technologies, we often only look at unit cost in large volumes. In that scenario, injection moulding seems unbeatable. But that comparison ignores the key element: the cost of entry. A technical mould can cost between 10,000 and 50,000 euros. That investment pays for itself if you produce tens of thousands of parts. But what happens when the volume is 300, 500 or 1,000 units? That's where the paradigm shifts. Additive manufacturing eliminates: When you look at total cost of ownership (TCO) and not just unit cost, industrial 3D printing is competitive at a much higher volume range than many companies imagine. Moreover, moulds are not getting cheaper. Steel, aluminium and machining processes are becoming more expensive. In contrast, the productivity of technologies such as HP Multi Jet Fusion continues to increase. The real mistake is not thinking that 3D printing is expensive. It's not crunching the numbers. Myth 2: “3D printed parts are not strong enough” This myth is a legacy of the first generations of domestic 3D printing. But today's industrial additive manufacturing works with technical materials such as: In technologies such as MJF, parts exhibit mechanical properties comparable to many injection moulded plastics, with low anisotropy and good dimensional stability. But beyond the technical data, there is something more relevant: structural freedom. 3D printing allows the design of optimised internal structures, cellular geometries, integrated reinforcements and consolidation of parts that would be impossible with traditional injection moulding. It's not just about replicating what already exists. It's about redesigning for the better. In many cases, the printed component doesn't just meet. It surpasses the original design. Myth 3: “3D printing is only for prototypes” This is probably the most limiting myth. The idea that there is a clear boundary between “prototype” and “final part” is no longer valid in industrial additive manufacturing. In technologies like MJF, the same process that produces a working prototype is the same process that produces a final part. There is no technological leap between the two phases. The difference is not in quality. It's in volume. And that's where many companies get stuck: they validate with 3D printing, but when it's time to produce, they automatically go back to the mould out of inertia. Without asking themselves if it's really the best option. Myth 4: “We've always done it this way” This is not a technical myth. It is organisational. In many companies, the flow is automatic: Design → Printed prototype → Validation → Mould. Not because it is optimal, but because it is known. The lack of real knowledge about industrial additive manufacturing is one of the biggest brakes. It is not a question of budget. It is a question of mentality. The real question should be: Does it make sense to invest in a mould for a part that changes every year? For a reference that is produced in batches of 400 units? For a product with a short life cycle? Often, the answer is no. But nobody stops the process to question it. Myth 5: “To produce in 3D, you have to buy machinery” Another common misconception. Industrial additive manufacturing doesn't necessarily require investment in your own equipment. There are specialised partners that allow you to completely outsource production, without assuming: This reduces risk and allows you to evaluate the technology with real data before making structural decisions. 3D printing does not require changing the entire organisation. It requires strategic decisions based on context and volume. The real change: from physical warehouse to digital inventory One of the most profound changes introduced by industrial 3D printing is not technical, but logistical. Traditionally, inventory is physical. Large quantities are produced to reduce unit cost and stored. But every part in storage is a gamble. If the product changes, those parts become obsolescence. Additive manufacturing makes it possible to turn the warehouse into a digital archive. Inventory ceases to be stock and becomes information. You make it when you need it. No minimums. No risk. No capital tied up. In sectors with high version turnover, this is not an incremental improvement. It is a strategic advantage. The invisible cost of not adopting additive manufacturing Not using 3D printing when it makes sense also has a cost. That cost doesn't show up on the invoice, but it does: In increasingly dynamic markets, agility is a competitive advantage. Additive manufacturing enables: And that's not a marginal advantage. It is a structural transformation. So... when not to use 3D printing? It's also important to be honest. Injection moulding is still unbeatable when: The key is not to replace injection moulding. It is to use each technology where it makes sense. The question is no longer: “3D printing or mould? The right question is: ”What volume, what complexity and how often do you change this product?“ How to make the leap without risk If your company is in that middle ground between prototype and series, the step doesn't have to be radical. Start with a reference, a component of less than 500 units, a part with lead time problems, a code that changes every year..., to compare real numbers. Not only unit price. But: The result is often surprising. Additive manufacturing is no longer the future. It is the industrial present. The market is no longer debating

How the drone industry is betting on HP 3D printing for lightness, scalability and speed
The professional drone and advanced drone industry is evolving at an enormous speed. From camera drones for inspection and surveillance, to critical solutions for defence, security, logistics or environmental conservation, the challenge is always the same: more performance, less weight and more adaptability. In this context, technologies such as HP Multi Jet Fusion (MJF) have become a standard for drone manufacturers, especially in demanding markets such as the United States, Germany and Denmark, where technical, regulatory and production requirements are increasingly high. Lightweighting: ultra-lightweight structures that extend the drone's mission One of the biggest challenges in the design of any camera drone, professional drone or advanced UAV is weight. Every gram counts: less weight means more range, longer range and more payload capacity. HP MJF technology enables manufacturing: This makes it possible to create the lightest airframes on the market, which is key for both civil drones and defence and security applications. A real-world example is the BushRanger project, a drone developed to combat poaching in extreme environments. Its founder, Robert Miller, explains it clearly: there was no commercial drone capable of meeting the requirements of durability, autonomy and field repairability. The solution came through industrial additive manufacturing. Advanced design impossible with traditional manufacturing Many drone manufacturers have tried classic materials and methods: HP MJF 3D printing removes these barriers and makes it possible to design: This is especially relevant for military drones, surveillance drones and professional drones, where reliability and performance are non-negotiable. At Additium3D we apply this same industrial approach to 3D printing projects for the defence sector, combining design, material and technology for critical environments. Real scalability: from prototype to mass production Another big reason why the drone industry relies on HP MJF is scalability. We're not just talking about printing parts, we're talking about industrial-scale production. With a single HP MJF machine it is possible: This is key in markets such as: Time to market: adapt quickly in an industry that does not wait The drone industry is constantly changing: new sensors, new regulations, new missions. This is where 3D printing makes the difference. Thanks to HP MJF, manufacturers can: In real projects it has been achieved: This directly impacts the competitiveness of any drone company, from FPV drone manufacturers to developers of advanced defence solutions. Modularity, flexibility and cost reduction One of the great differentiating values of additive manufacturing is modularity. In the case of BushRanger, the drone was designed to integrate interchangeable sensors, such as radars capable of detecting traps from the air. According to its founder, the use of MJF allowed: "This flexibility is key for both professional drones, as well as for manufacturers looking for the best drone for the price or to develop better drones for the price without compromising performance. From small components such as camera mounts or battery clips to complete airframes, HP MJF 3D printing is establishing itself as the key technology for the future of drones, both civil and defence. At Additium3D we work precisely at this intersection between engineering, additive manufacturing and critical applications, helping companies move from idea to real industrial product, with scalable, lightweight and optimised solutions.

Arkema's Polyamide 12 S: the key to making industrial 3D printing profitable
Arkema's Polyamide 12 S (PA12 S) has become one of the most demanded materials in industrial 3D printing thanks to its combination of strength, precision and adaptability, making it a strategic ally for companies looking for innovation, efficiency and cost reduction. At Additium3D, we use this polyamide especially in the Jet Fusion 5600 Series Printer, which combines speed and precision, positioning 3D printing as a cost-effective alternative to plastic injection, even in medium and large batches. What is Arkema Polyamide 12 S Arkema PA12 S is a high performance thermoplastic widely used in industrial applications. Its properties are outstanding: Thanks to these characteristics, PA12 S is ideal for functional parts, final prototypes and small to medium-sized production runs, especially when combined with multi-agent jet fusion technologies, such as HP's Jet Fusion 5600 Series. Why industrial 3D printing is cost-effective versus plastic injection moulding For years, 3D printing was considered useful only for prototypes and proof-of-concepts, while plastic injection moulding dominated mass production. However, the combination of MJF technologies, advanced materials such as PA12 S and process optimisation has changed the economic equation. 1. Flexibility versus mould rigidity Injection moulding requires expensive moulds, with costs that can exceed €15,000-50,000, and limits production to a fixed design per mould. Each modification requires a new mould, causing delays and additional costs. With industrial 3D printing, each design iteration is transformed directly into a digital file, ready to print, with no extra tooling costs or long lead times. This allows companies to continuously improve their parts and adapt quickly to market changes or customer requirements. 2. Profitability in medium and large batches In the past, 3D printing only paid off economically for small batches (100-500 units), while injection moulding dominated from 1,000-2,000 parts. Today, thanks to the efficiency of the Jet Fusion 5600 Series and the cost reduction of materials such as PA12 S, 3D printing becomes competitive even in batch sizes of 5,000-15,000 parts. This opens up opportunities for companies looking to: 3. Reduce hidden costs 3D printing with PA12 S eliminates many costs that injection moulding does not show at first glance: Cost comparison: MJF vs Injection moulding Data from industrial platforms such as Weerg show that, for PA12 S parts: In addition, the production speed of the Jet Fusion 5600 enables cycle optimisation, reducing downtime and increasing return on investment, which is difficult to achieve with traditional injection moulding processes. Industrial applications of PA12 S with MJF The combination of PA12 S and MJF is used in sectors such as: An outstanding case is the collaboration of Additium3D with the Hospital La Fe in Valencia, developing high precision medical prototypes: high resolution brain scanner project. This example shows how 3D printing with PA12 S enables the development of functional, fast and safe solutions, even in critical environments such as healthcare. Strategic advantages of PA12 S in industrial production How 3D printing with PA12 S and Jet Fusion works The Jet Fusion 5600 Series uses a Multi Jet Fusion (MJF) process that combines heat and fusing agents to solidify Polyamide 12 S layer by layer: This process is ideal for medium to large series, where speed of production and repeatability are critical factors for efficiency and profitability.

What is HP Multi Jet Fusion technology? HP Multi Jet Fusion (MJF) is a high-performance industrial 3D printing technology, based on powder sintering, which enables the production of functional parts in series with precision and speed. It is based on powder sintering, similar to SLS (Selective Laser Sintering), but with significant advantages that make it faster and more precise. While SLS uses a laser to fuse the powder layer by layer, MJF applies a fusing agent precisely to specific areas of the powder, followed by the application of heat that solidifies the particles uniformly. This allows for greatly accelerated production times and a much more uniform finish between parts. MJF technology stands out: With these features, the HP Multi Jet Fusion has established itself as the industry's most widely used choice for additive manufacturing, especially in environments where quality, repeatability and efficiency are essential.

How HP Multi Jet Fusion technology works HP MJF printing is based on a very precise powder fusion process: This method allows precise results, with consistent tolerances and no deformations, even in complex geometries. In addition, the use of detailing agents facilitates the creation of parts with fine details and uniform textures, which sets it apart from other 3D printing technologies. Advantages over other 3D printing technologies Compared to other additive manufacturing techniques, HP Multi Jet Fusion offers distinct advantages: For these reasons, HP Multi Jet Fusion has become the technology of choice for automotive, medical, robotics, electronics and other industries seeking fast, precise and scalable manufacturing. Compatible materials: Arkema's Polyamide 12 S One of the main materials used in the HP MJF is Arkema's Polyamide 12 S. This polymer is ideal for industrial applications thanks to its mechanical strength, durability and thermal stability. It is also highly recyclable, allowing companies to reduce the environmental impact of their production. Polyamide 12 S can be used to manufacture: With this material, HP MJF ensures that parts are not only precise, but also functional and ready for real applications in industrial environments. HP Multi Jet Fusion applications The versatility of this technology makes it suitable for multiple industries: Thanks to HP MJF, industries such as automotive, medical or electronics can produce complex parts with uniform finishes and consistent tolerances.

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. Where to get 3D business or reference models If your company is looking for base models to develop new products, there are platforms with professional resources: Also, if you already have your design, learn how to prepare and submit your STL file for 3D printing.

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.

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.

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.
