Additive manufacturing process for forming a metal part using ceramic support and bodies formed thereby

Abstract

A method of manufacturing a part formed of metal, a method of determining a ceramic support structure for the metal part, and an un-sintered metal part including the ceramic support. The method of manufacturing the part includes forming a metal part and forming a ceramic support by depositing a ceramic composite material in a pattern to form ceramic print layers. The ceramic support supports a supportable portion of the metal part. The method of determining the ceramic support structure for the metal part includes determining, (i) a composition of a ceramic filament used to produce the ceramic support or (ii) a geometry of an infill of the ceramic support such that the ceramic support has a strength sufficient to support the supportable portion prior to sintering and is deformable to allow the supportable portion to undergo geometric changes during sintering.
