The M100 works by turning powdered cobalt-chrome, stainless steel or titanium raw material into a variety of complex parts. It uses a powerful laser and steerable mirrors to precisely trace the item under construction out of a bed of powdered raw material. The laser's beam selectively melts the metal particles in the shape of the object, and the molten metal solidifies to form the item one thin layer at a time. After each layer solidifies, the M 100 begins the next one by lowering the circular build stage and laying down a new layer of raw material.

At 200 watts, the ytterbium laser has a focus spot of 5 microns and builds the object in precise 30-micron slices. One thing to be aware of with this printer is that the M 100 requires the use of a nitrogen- or argon-inert atmosphere in order to build objects. The system needs 60 pounds per square inch of gas pressure available from either individual tanks or a building-wide gas delivery system.
