    摘要: A three dimensional printing system includes a light engine having a spatial light modulator for curing individual layers of a photocure resin to form a three dimensional article of manufacture. The light engine is configured to: (1) receive a slice image that defines an array of energy values for curing a layer, (2) process the slice image to define an image frame compatible with the spatial light modulator, (3) receive an on signal, (4) activate the first light source in response to the on signal; (5) repeatedly send the first defined image frame to the first spatial light modulator during a defined cure time for the single layer of resin; (6) receive an off signal; (7) deactivate the first light source in response to the off signal; and (8) repeat steps (1)-(7) until the three dimensional article of manufacture is formed.

    摘要: 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.

    摘要: A three dimensional (3D) printer generates 3D articles of manufacture through the selective hardening of light curable liquid resins. The 3D printer includes a vessel, a fixture, a movement mechanism, a light engine, a controllable pressure source, and a controller. The vessel contains light curable resin with a bottom portion including a transparent sheet. The light engine selectively illuminates a lower face of a 3D article of manufacture being formed through the transparent sheet. The fixture and movement mechanism selectively translate the lower face up and down which generates a varying pressure of the resin against a top surface of the transparent sheet. The controllable pressure source applies a gas pressure to a bottom surface of the transparent sheet to offset the varying pressure of the resin.

    摘要: 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.
