INSERTING INHIBITOR TO CREATE PART BOUNDARY ISOLATION DURING 3D PRINTING

摘要

A 3D printing system may print a desired 3D object. A fusible powder may fuse when subjected to a fusing condition. A deposition system may deposit portions of the fusible powder on a substrate. A fusing system may apply the fusing condition to the deposited fusible powder. Inhibitor material may not fuse when subjected to the fusing condition. An insertion system may insert a portion of the inhibitor material between portions of the deposited fusible powder after having been deposited by the deposition system, but before being fused by the fusing system, so as to form a boundary that defines at least a portion of a surface of the desired 3D object.

1. A 3D printing system for printing a desired 3D object comprising:
a fusible powder that fuses when subjected to a fusing condition; a deposition system that deposits portions of the fusible powder on a substrate; a fusing system that applies the fusing condition to the deposited fusible powder; inhibitor material that does not fuse when subjected to the fusing condition; and an insertion system that inserts a portion of the inhibitor material between portions of the deposited fusible powder after having been deposited by the deposition system but before being fused by the fusing system so as to form a boundary that defines at least a portion of a surface of the desired 3D object.
