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: A material for producing a three-dimensionally printed part including a metal material and at least one sintering aid in an amount effective to give the three-dimensionally printed part a density of between about 90% and about 100% after sintering is disclosed. A method of printing a three-dimensional part including selecting a metal material, incorporating at least one sintering aid into the metal material to form a print material, and printing the three-dimensional part is also disclosed. A method of producing a sintered metal part including providing a metal material for the sintered metal part incorporating boron as a first sintering aid, incorporating phosphorus as a second sintering aid, forming the metal part in a predetermined form the metal material, and heating the formed metal part to a sintering temperature is also disclosed. Three-dimensionally printed parts are also disclosed.
