Industrial 3D printing company EOS has added a new machine to its EOS M 290 family, the EOS M 290 1kW.

Designed with serial production in mind, this new Laser Powder Bed Fusion (LPBF) metal additive manufacturing (AM) platform can meet the specific needs of copper and copper alloys that are often difficult to process for applications heat exchangers and inductors.

As a matter of fact, the machine’s launch comes along EOS Copper CuCp and EOS Copper CuCrZr materials which are already qualified for the platform. Other materials will be developed later on in 2024.

One early adopter of the technology was GBZ Mannheim GmbH & Co.KG, a specialized manufacturer of inductors and other highly engineered components to the automotive industry.

Additive manufacturing and the new one-kilowatt technology allow us to design and manufacture copper inductor applications that are more capable, durable and now produced in one piece with no soldering points,” said Thomas Corell, managing director at GBZ Mannheim. “The core elements of inductor applications are now integrated in a single build, and the results are much higher optimization of the cooling channels, lower power consumption during the product lifecycle, and we are seeing great reproducibility on the production-side of things.”


Main features of the 3D printer include:

  • Build volume: 250 x 250 x 325 mm (9.85 x 9.85 x 12.8in)
  • Powerful: One (1) 1,000-Watt laser
  • Productive: A volume rate of up to 55.4 (cm³/h)
  • Scanning speed: up to 7.0 m/s (23 ft./sec)
  • Focus diameter: ~ 90 µm

Already available for purchase, the EOS M 290 1kW can be used across the space, energy, and mobility/transportation industries.
