Q. What are the material properties of a laser-deposited alloy? DMD produces pure, fully dense metal with density, physical and mechanical properties that equal or exceed those of conventionally quenched and tempered wrought alloys. Q. What is the accuracy of the DMD process? DMD fabricates the work piece to near-net shape and leaves 0.007″-0.010″ excess material prior for final finishing. Final finish is achieved through conventional polishing or EDM. Q. What is the surface roughness of the metal surface? The typical roughness of the laser-deposited surface is Rt of 150 – 200 microns and Ra of 10-25 microns. Q. What is the
