Abstract: Systems, apparatus and methods of additively manufacturing objects are disclosed. Specifically, provided herein are methods of heating objects having a particle-based support at least partially surrounding the object during portions of stages of the heating. Additionally, systems, apparatus, and methods for removing the particle-based support during heating, such that the object can continue heating to form a final part. Systems, apparatus, and methods for distributing the particle-based support to shore the objects through heating are disclosed. Systems, apparatus, and methods for removing the particle-based support are also disclosed herein.

Abstract: Method of manufacturing a metal matrix composite part and ceramic preform assembly for use in the method. The method includes forming a ceramic preform using 3D printing, sintering the ceramic preform to form a sintered preform, introducing a liquid metal into the sintered preform to form the metal matrix composite part. The ceramic preform may be part of a ceramic preform assembly includes at least one ceramic preform and an infiltrant reservoir connected to the ceramic preform. The method may also include forming the ceramic preform assembly using 3D printing.

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.

Abstract: A 3D printing apparatus and method includes a piezo actuator that reciprocates a tappet. The reciprocation of the tappet generates pressure within a chamber filled with molten print material. The generated pressure causes the molten print material to be extruded through a nozzle coupled to the chamber. The piezo actuator is controlled to switchably provide continuous extrusion of print material or extrusion of discrete droplets of print material.
