What is Bound Metal Deposition (BMD)?
Bound Metal Deposition (BMD) is an extrusion-based metal additive manufacturing (AM) process where metal components are constructed by extrusion of a powder-filled thermoplastic media. Bound metal rods—metal powder held together by wax and polymer binder—are heated and extruded onto the build plate, shaping a part layer-by-layer. Once printed, the binder is removed via the debind process, and then sintered—causing the metal particles to densify. Prevalent metal AM technologies involve melting powder or wire feedstock using [...]
