1 DIRECT METAL DEPOSITION ( Manufacturing at the Speed of Light) Steve Krar With new technologies evolving almost every week, it was just a matter of time before someone would experiment by blending a number of technologies to come up with something new. POM, Inc., (Precision Optical Manufacturing) of Auburn Hills MI combined CAD, CAM, lasers, sensors, and powder metallurgy to develop the Direct Metal Deposition (DMD) process. It might well be the PUT-ON tool many of us wished we had after making machining errors during our early years in the trade. Direct Metal Deposition (DMD) DMD is a form of rapid tooling process that makes parts and molds from metal powder that is melted by a laser, and then solidified in place. This process closely resembles conventional rapid prototyping processes (material processed by laser under computer control) but differs in that metal powder, and even tool steel, can be melted rather than plastic polymers. DMD allows the production or reconfiguration of parts, molds and dies that are made out of the actual end material, such as tool steel or aluminum. It always produces a new part or part reconfiguration directly from a CAD drawing. DMD is the blending of five common technologies: lasers, computer-aided design (CAD), computer-aided manufacturing (CAM), sensors, and powder metallurgy. The resulting
