Eplus3D, a manufacturer of industrial metal additive manufacturing systems, Rosswag Engineering, the additive manufacturing division of German metal processing company Rosswag GmbH, and qualloy, a supplier and marketplace for metal powders used in additive manufacturing, have signed a memorandum of understanding to jointly advance next-generation metal additive manufacturing systems and supply chains. As part of the agreement, Rosswag Engineering will invest in an EP-M550 MPBF system from Eplus3D with a 550 × 550 × 450 mm build envelope and eight lasers. The machine will be installed at the German firm’s new additive manufacturing facility, which is currently under construction, and will be available from June 2026 for customer-specific testing, validation, and application development.
This investment marks a further step in the engineering division’s strategy to expand its industrial additive manufacturing capabilities toward larger and more complex components. The collaboration combines the system maker’s large-scale industrial metal PBF platforms, Rosswag’s expertise in metal processing, heat treatment, machining, testing, and qualification, and qualloy’s metal powders designed for those systems. Joint work will cover material qualification and parameter development, with the powder supplier acting as a supply chain facilitator and Rosswag contributing qualification and testing expertise according to industry standards for components produced on the LPBF platforms.
qualloy metal powder designed for the systems will be systematically qualified at the company’s Innovation Center in Korntal-Münchingen. Following qualification, those materials will be made available to users of the machine maker’s systems through its online shop with validated process parameters and powder specifications. The companies stated that the aim is to validate industrial-grade process performance and develop user-ready applications and benchmarking capability within an integrated manufacturing ecosystem.
Applications for the new system include energy machinery, pressure-bearing components, heat exchangers, and broader industrial use. These fields require reliable, validated manufacturing processes and benefit from the design freedom and scalability of large-format metal 3D printing. “By combining our large-scale, industrial LPBF systems with Rosswag’s application expertise and qualloy’s material excellence, we are creating a fully integrated ecosystem that significantly lowers the barrier for true serial additive manufacturing. This collaboration is not just about technology, but about delivering validated, production-ready solutions with great part pricing that enable our customers to scale with confidence,” said Enis Jost, Deputy General Manager, Eplus3D Tech GmbH.
“The EP-M550 combines a compact machine design with very high productivity and a large build envelope. This is an important step toward larger and functionally optimized LPBF components. It allows us to begin closing the gap between today’s additively manufactured parts and complex large-scale forged and machined components. Combined with our integrated process chain, we are well positioned to bring additive manufacturing into industrial-scale applications,” said Dr.-Ing. Sven Donisi, CEO, Rosswag GmbH. “We’re excited to partner with Eplus3D to develop a qualified powder line for their systems. With validated, high-quality and cost-efficient materials, we provide customers with an optimally matched material and process setup to drive industrial additive manufacturing toward scalable serial production,” added Yannik Wilkens, CEO, qualloy GmbH. Rosswag Engineering supports industrial customers in developing and validating high-performance components across more than 50 materials.
The three companies will present the collaboration at Rapid.Tech 3D in Erfurt, Germany, from May 5 to 7, 2026. Eplus3D will exhibit at booth 2-316, while qualloy and Rosswag will exhibit at booth 2-228.
Eplus3D’s expansion push meets the demands of scale
Eplus3D’s recent growth has been tied to large-format, multi-laser metal powder bed fusion systems aimed at industries that need large, complex metal parts. Last year, the manufacturer said it had delivered more than 100 “super-meter” metal LPBF systems worldwide, including nearly 40 machines with X, Y, and Z axes each measuring more than one meter. That portfolio includes platforms such as the EP-M2050, EP-M1550, and EP-M1250, and has already been used in demanding projects including a 1.3-meter single-piece rocket thruster developed with LEAP 71.
That expansion has also exposed the constraints around scaling. Eplus3D withdrew its planned IPO on Shanghai’s STAR Market after seeking to raise RMB 1.2045 billion for capacity expansion, equipment industrialization, a new R&D center, and a larger global service network. Financial disclosures showed revenue rising from RMB 247 million in 2022 to RMB 471 million in 2024, but accounts receivable also climbed to RMB 216.73 million by the end of 2024, equal to 46.04% of annual revenue. At the same time, the company disclosed continued dependence on imported core components such as lasers and galvanometers. Those pressures help explain why the new partnership is centered not on machine sales alone, but on qualification, powder supply, testing, and process validation.
