La Industrial 3D printing is experiencing a qualitative leap thanks to a new generation of equipment and with which is aimed directly at production, and not just prototyping. From much more affordable metal systems to large resin platforms and pellet solutions for engineering plastics, the European landscape is beginning to fill with options that were previously reserved for large manufacturers.
In parallel, digital tools are being consolidated that They automate tool design, integrate fleet management, and simplify workflowsMeanwhile, demanding sectors such as the military are exploring how to bring additive manufacturing to the front lines or advanced bases to gain autonomy and accelerate maintenance.
Metal 1.0: a low-cost metal 3D printer for industrial use
The arrival of the Metal 1.0 printer, developed by Dutch engineer Thomas Martinus Gerardus Bakker through his company Metal Base, represents a game-changer in the field of Industrial 3D printing in metal using laser powder bed fusion (LPBF)The system has been financed through a crowdfunding campaign that has far exceeded the initial goal and is positioned as an entry alternative in a segment that has been prohibitively expensive until now.
Compared to classic LPBF machines, which usually require investments exceeding 100.000 eurosWith dedicated facilities and highly specialized personnel, the Metal 1.0 is presented as a compact unit, designed to be placed directly on the workshop floor and connected to a standard electrical outlet. This approach opens the door for European laboratories, startups, technology centers, and small R&D departments to produce metal parts with near-industrial density without the need for large-scale infrastructure.
The cost-containment approach rests on two pillars: on the one hand, a redesign of the optics and motion systems To maintain fusion quality while minimizing component costs, the system is marketed as a kit. The user assembles the machine following a step-by-step manual, bolting the frame, assembling the gantry, and connecting pneumatics and wiring. Meanwhile, the more delicate components—such as the laser optics or high-precision Z-axis modules—arrive pre-assembled from the factory to reduce risks.
In terms of capabilities, the Metal 1.0 is designed to work with standard metal powders available on the marketThis avoids the proprietary cartridges commonly used in many industrial solutions. The manufacturer states that they have already achieved virtually full densities in 316L stainless steel and Inconel 718, around 94% in bronze, and approximately 80% in copper, the latter still undergoing validation. The initial working volume is 128 × 100 mm, expandable to 128 × 150 mm with a paid upgrade, making it suitable for components such as functional supports, tooling, jewelry, or small technical parts.
In the digital section, the machine relies on Klipper firmware and workflow with OrcaSlicerThis facilitates integration into established 3D printing environments and allows technical teams to adapt parameters with relative freedom. With a significant portion of the initial units already reserved, shipments are planned in several batches throughout the year, and it remains to be seen how the European market will respond to a proposal that democratizes LPBF without abandoning its industrial focus.
3D printing of plastic for production: pellets and resin on a large scale
While metal gains ground, the industrial 3D printing of polymers It is also advancing strongly thanks to two clear trends: the use of plastic granules instead of filament and the scaling up of stereolithography towards large-scale, high-productivity platforms.
On the one hand, manufacturers like Bosch have promoted solutions for 3D printing using pellets for high-precision plastic partsDeveloped under the Bosch Industrial Additive Manufacturing brand, these machines work directly with the same... granulated which is used in injection molding, so that the leap from the printed prototype to the serial part is significantly reduced, both in mechanical properties and in behavior during assembly tests or functional validations.
By using original industrial materials in pellet form, the resulting pieces can achieve mechanical strengths comparable to or greater than injection moldingProvided the process is properly aligned and controlled, this translates to shorter development cycles, faster iterations, and pilot or low-volume production runs without the need for expensive molds, which aligns well with flexible production strategies.
Meanwhile, companies like 3D Systems are strengthening their product range with systems like the SLA 750 Dual, a printer of large format stereolithography that integrates two lasers working in parallel within a volume of 750 × 750 × 550 mmThis architecture multiplies the manufacturing speed compared to single-laser equipment, allowing the platform to be filled with numerous parts or large components to be handled in tighter production times.
The deployment of this machine is complemented by 3D Connect, a software platform geared towards centralized management of industrial 3D printer fleetsReal-time monitoring, queue management, alerts, remote maintenance, and data analysis focused on reducing unplanned downtime. The idea is clear: if additive manufacturing is to become a standard production line within the factory, more than just hardware speed is needed; the operation must be controlled like any other production cell, with indicators, supervision, and traceability.
Software and workflow automation in industrial 3D printing
Beyond the equipment, the industry is beginning to realize that the real bottleneck of the Industrial 3D printing is no longer just about the machine.but in the design and preparation of the parts and tools. This is where solutions like Additive App Suite from the Berlin-based company trinckle come into play, expanding its integration with the Stratasys ecosystem.
The suite, accessible via the web, now integrates with GrabCAD Print and GrabCAD Print Pro It's designed for production environments where 3D printers are available, but resources or advanced CAD knowledge are lacking. Instead of manually modeling each tool in design software, the operator enters a few parameters and the system automatically generates the printable model ready for production.
The focus is on auxiliary elements for manufacturingThese include robot gripping fingers, clamping jaws, logistics trays, shadow boards, and support templates. A particularly useful feature is the "Photo-to-Outline" function, which allows you to create the outline of a part from a simple photograph taken with a mobile phone. This solves a very common problem in many workshops: a tool is needed, but there's no pre-existing 3D model, and creating one from scratch would be too time-consuming.
The platform is still in open beta, but its developers are already working on expand the catalog with new applicationsThese include tools such as drilling templates, 3D-printable break labels, and masking tools. Taken together, these developments point toward industrial 3D printing where operators don't need to be design experts to use the technology in their daily work, which aligns with the reality of many European factories with limited engineering resources.
Defense and maintenance: 3D printing enters the military field
Another area where industrial 3D printing is starting to gain traction is in the defense and maintenance of military assetsEuropean armed forces have long been analyzing how additive manufacturing can reduce dependence on long supply chains and enable local production of critical spare parts.
In Spain, the company Meltio —based in Linares (Jaén— has specialized in technologies of 3D printing in metal geared towards repair and manufacturing of parts for demanding applications. The company has collaborated with the Army in the production of stainless steel spare parts for armored vehicles, and with the Air Force and Space Force in the repair of jet engine components using titanium and copper alloys.
The goal, for both manufacturers and the armed forces, is to bring 3D printing as close as possible to the point of use: forward bases, ships, remote environments, or mobile logistics facilitiesIn these scenarios, being able to print a metal part on demand can make the difference between keeping an operating system running or leaving it out of service for weeks waiting for a traditional replacement part.
This evolution fits with a broader vision where industrial 3D printing is not only used for prototyping, but also for extend the lifespan of equipment, facilitate maintenance, and adapt existing platforms to new needs. The Spanish experience with solutions like Meltio's reinforces the idea that additive manufacturing can become a standard tool within European military logistics in the coming years.
Overall, the combination of More accessible metal systems, production-oriented polymer platforms, software that automates design, and applications in critical sectors such as defense It paints a picture in which industrial 3D printing ceases to be a niche technology and becomes a common resource in factories, laboratories and maintenance centers in Spain and the rest of Europe, with a growing impact on costs, response times and production flexibility.
