EOS’ M 290 1kW metal printer, part of the EOS M 290 family, is specifically designed for copper and copper alloy 3D printed applications. This metal additive manufacturing (AM) platform was designed with serial production in mind, as a variant of its robust industry standard, but equipped with a 1 kW laser to handle challenging copper applications.

The EOS M 290 1kW was developed by EOS’ AMCM group to support the and manufacturing of copper inductor applications and is well suited for a wide range of industries, including , and mobility/transportation. These industries typically leverage copper and copper alloys, where the challenge of 3D printing copper applications (like heat exchangers and inductors) is overcome with the powerful laser and other technologies and materials working in tandem. At launch, EOS Copper CuCp and EOS Copper CuCrZr materials are fully qualified on the system, and additional materials will be added to the machine compatibility portfolio later in 2024.

The high beam quality of the 1kW laser spot and the detailed resolution are well suited for producing highly complex components that require high intensity. With the 1,000 watts made available through this system, it is specialized for processing copper applications.

The EOS 290 1kW features a build volume of 250 × 250 × 325 mm (9.85 × 9.85 × 12.8"). It has a powerful 1,000-W laser with a volume rate of up to 55.4 (cm³/hr.), a scanning speed up to 7.0 m/sec. (23 ft./sec.) and a focus diameter of approximately 90 µm.
