Abstract:
A three-dimensional printing system includes a build platform, a movement mechanism, a coating module, a consolidation module, and a controller. The controller is configured to (1) operate the movement mechanism and the coating module to deposit a new powder layer over an upper surface of the build platform or powder, (2) operate the consolidation module to selectively consolidate the new powder layer, and (3) repeat (1) and (2) until a three-dimensional article is fabricated from a plurality of layers. Step (1) includes, at least one of the plurality of layers (a) operate the movement mechanism and the coating module to deposit a first sublayer of powder having a thickness T1 over the upper surface, and (b) operate the movement mechanism and the coating module to deposit a second sublayer of powder having at thickness T2 over the first sublayer of powder. T2 is less than 20% of T1.
