AMCM: 2 models

AMCM is part of the EOS group, based in Starnberg near Munich, and builds customized laser powder bed fusion (LPBF) systems for metal. Its machines start from the EOS M 290 and M 400 platforms, which AMCM adapts in build volume, laser power, wavelength, gas flow or process monitoring for a specific application. The two catalog models are the M 290 FLX, an M 290 in flexible configuration, for example for higher laser power or alternative wavelengths suited to copper alloys, and the M 4K, which extends the build height considerably for tall components such as rocket engine chambers. Users are concentrated in space propulsion, aerospace, energy and research.

Used AMCM systems are rare, because production numbers are small and most machines were bought for a defined part family. Listings usually result from the end of a program, a restructuring or capacity reductions at service providers. Both models are current and have no announced successor; the M 4K has been delivered in several configurations featuring one or four lasers, so the exact build must be verified case by case.

The first step in any purchase is documenting the machine's special equipment, since spare parts and parameter sets are tied to that configuration. The software environment is the EOS stack (EOSPRINT, EOSTATE), parameters are editable, and powder can be sourced from any supplier. Check laser operating hours, optics, protective glass, the filter unit and the recirculation system, and go through the maintenance records. Operation requires argon or nitrogen, compressed air, a 400 V three-phase supply and ATEX-compliant powder handling; for the M 4K, floor loading and ceiling height also matter. Below you will find the technical data of both AMCM models in our catalog, and which of them are currently available used.
