Featuring four, one kilowatt lasers to deliver the power, performance and reliability needed to maximize production of aluminum and copper applications

EOS, leading supplier of responsible manufacturing solutions, is launching the newest member of the EOS M 300 family, the EOS M 300-4 1kW. This new metal additive manufacturing (AM) system boasts four powerful, one kilowatt lasers to meet the demanding production requirements of aluminum and copper 3D printed applications, such as aluminum brackets, holders, antennas, heat exchangers; and copper or copper alloy heat exchangers, inductors, e-mobility components, and more.

“The EOS M 300-4 has already proven to be a highly productive AM machine for our customers, but we need to meet the growing market demand of challenging materials like Copper and high productivity processes,” said Sebatian Becker, EOS Metal Systems Lead. “The EOS M 300-4 1kW delivers the power and productivity at the highest level of reliability, needed to achieve the lowest cost-per-part in the industry.”

The EOS M 300-4 1kW features:

• A build volume of 300x300x400mm (11.8x11.8x 15.8in)
• Four (4) one kilowatt lasers
• Reliable 2-axis scanning units for maximized build efficiency
• The best cost per volume (example: AlSi10Mg)
  • ​Layer thickness: 80 µm​
  • Build rate: 4 x 38.5 mm³/s = 154 mm³/s (555 cm³/h)​
  • Minimum relative density: 99.5 %, tensile strength: 350 MPa, yield strength: 205 MPa, elongation at break:3-5 %

At launch, the EOS M 300-4 1kW is ideal for applications in aviation, energy, government and defense, and mobility/transportation industries that leverage AlSi10Mg, CuCP and CuCrZr. Beginning in 2024, the system material portfolio expands and will also include Nickel base alloys, Titanium, Cobalt Chrome, Steels and StainlessSteels, and the new high-strength and anodizable Aluminum Alloy Al5X1 – the latter material also being launched at Formnext 2023.
