摘要： 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.
