Here's a little more detail: https://www.theverge.com/circuitbreaker/2017/4/26/15440744/desktop-metal-studio-printer-3d-printing-manufacturers https://www.theverge.com/circuitbreaker/2017/4/26/15440744/d... The important thing to remember is that the 3D printing doesn't generate the final part, the plastic binder in the filament has to be burned out and then the part has to "densify", e.g. the actual sintering where the metal particles fuse together creates the final material properties of the part. The final part will be a lot smaller than the thing coming out of the 3D printer, controlling uniform shrinkage is probably a lot of the secret sauce.
