Abstract: A three-dimensional printing system for fabricating a three-dimensional article includes a resin vessel, a motorized build plate, an imaging bar, and a movement mechanism. The resin vessel is for containing a photocurable resin, the photocurable resin having an upper resin surface. The motorized build plate is for supporting the three-dimensional article in the photocurable resin. The imaging bar includes a plurality of light emitting devices arranged along a transverse axis for emitting light generally downwardly and a transparent sheet disposed below the plurality of light emitting devices. The transparent sheet has a lower surface to contact the resin and define a build plane below the upper surface of the resin. The movement mechanism is for imparting movement of the imaging bar along a scan axis.

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 fixture, and a controller. The print engine further includes a vessel, a light engine, and a movement mechanism. The vessel is for containing a photocurable resin and has a lower portion with a transparent sheet defining a lower surface of the vessel. The light engine is configured to project radiation up through the transparent sheet over a lateral build plane which defines a maximum addressable lateral range of the light engine. The fixture has a lower face that faces downwardly. The controller is configured to: (1) position the lower face of the fixture at the build plane, and (2) operate the light engine and movement mechanism to solidify a particle trapping sheet proximate to the transparent sheet and substantially spanning the build plane and to thereby trap particles that are present along the build plane.
