Abstract: A three dimensional printing system includes a resin vessel, a light engine, a movement mechanism, a fixture, and a controller. The resin vessel is for containing a photocurable resin and has a lower portion with a transparent sheet. The light engine is configured to selectively project radiation up through the transparent sheet and over a build plane. The fixture is coupled to the movement mechanism and has a lower face that faces the transparent sheet. The controller is configured to operate the light engine to solidify a particle trapping sheet proximate to the build plane thereby trapping particles that extend upwardly from the transparent sheet into the build plane.

Abstract: A three dimensional printing system includes a print engine, a fluid processing station, a fixture, a transport mechanism, and a controller. The fluid processing station includes a fluid injector port coupled to a fluid source. The fixture has a lower portion with a lower face and a first fluid conduit coupled to the lower face. The controller is configured to: (a) Operate the print engine to form a three dimensional article of manufacture onto the lower face and thereby defining an internal cavity and an inlet port that couples the internal cavity to the first fluid conduit of the fixture. (c) Transfer the fixture to the fluid processing station. (d) Couple the fluid injector port of the fluid processing station to the first fluid conduit of the fixture. (e) Operate the fluid source to inject fluid out of the fluid injector port and into the internal cavity.
