Desktop Metal

How it works

1. PRINT
For each layer, the printer spreads metal powder across the build bed, and precisely jets a binding agent to bond loose powder and define part geometry. Layer by layer, metal powder and binder is deposited until the entire build volume is packed with bound parts and surrounding loose powder.

 

 

2. DEPOWDER
Once an entire build is complete, the build box is removed and placed in a powder station for bulk and fine depowdering—with the help of a hand-held air pick. Loose powder is removed from the parts and recovered via a built-in powder recycling system with powder sieving.

3. SINTER
Depowdered parts are placed onto trays in a shop-safe, high-throughput furnace for batch sintering. With an external gas hookup and temperatures reaching 1400ºC, the Shop System furnace is able to deliver quality and reliable sintering in a shop-friendly format.
