EOS launches an upgraded version of its metal 3D printer supporting aluminium material production

EOS is introducing upgraded version of its EOS M 300-4 metal additive manufacturing equipment with four 1kW lasers. The EOS M 300-4 1kW has been specifically designed to fulfil the production demands of many applications using aluminium and copper materials. These applications include the manufacturing of brackets, holders, antennas, and components related to e-mobility.

The M 300-4 system by EOS was introduced onto the market a few years ago and has been used by several companies, such as Material Solutions, Incodema3D, and Rennscot MFG. EOS has successfully included 1kW lasers into their quad-laser metal technology, resulting in a significant increase in productivity compared to the conventional M 300-4 model that employs four 400W lasers.

"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. The EOS M 300-4 1kW delivers power and productivity at the highest level of reliability to achieve the lowest cost-per-part in the industry," said Sebastian Becker, EOS Metal Systems Lead.

The four 1kW lasers work throughout a build volume of 300 x 300 x 400 mm and contribute to a build rate of 154 mm3/s, layer thickness of 80m, and relative density of 99.5 per cent. The newest EOS machine is also stated to have a tensile strength of 350 MPa, yield strength of 205 MPa, and elongation at a break of 3-5 per cent.

The EOS M 300-4 1kW, which will be commercially available in February 2024, is compatible with AlSi10Mg, copper, and copper alloys, with the material selection for the system to be increased based on client needs. To 'further enhance' the product offering, EOS is also provided the Volkmann PowTrex EOS Edition powder handling system, with additional information to be disclosed later in 2023. The EOS M 300-4 1kW will be shown and demonstrated at Formnext 2023 in Frankfurt, Germany, from November 7 to 10, in Hall 11.1, Booth D41.

“Additive manufacturing offers transformative potential, especially for products like aluminium cylinder heads that were traditionally made by diecasting. The speed and power of new AM platforms, like the EOS M 300-4 1kW, allow us to manufacture complex components, while ensuring enhanced design flexibility, weight reduction and readiness for future emission standards. To rival conventional methods, AM's cost-effectiveness is vital and systems like the EOS M 300-4 1kW offer the possibility to achieve this. Thus, our partnership with EOS aims to maximize productivity and push AM's competitive boundaries,” added Manja Franke, Chief Strategy Officer at AMEXCI, a leading AM company in the Nordics.
