ADDITIVE FABRICATION OF SINTERABLE METALLIC PARTS VIA APPLICATION OF DIRECTED ENERGY
Publication/Patent Number: US2020298475A1 Publication Date: 2020-09-24 Application Number: 16/824,987 Filing Date: 2020-03-20 Inventor: Myerberg, Jonah Samuel   Hart, Anastasios John   Assignee: Desktop Metal, Inc.   IPC: B29C64/153 Abstract: According to some aspects, techniques are provided for fabricating sinterable metallic parts through the application of directed energy to a build material. In particular, applying energy to a build material comprising a polymer mixed with a metal powder may cause the polymer to form a cohesive structure with the metal powder. As a result, the polymer acts as a “glue” to produce a metallic green part without local melting of the metal. The green part may subsequently be sintered to remove the polymer and produce a fully dense metal part. Optionally, a step of debinding may also be performed prior to, or simultaneously with, sintering.
