    Abstract: A three dimensional printing system includes a vertical support, a support plate, a resin vessel, a fluid spill containment vessel, and a light engine. The support plate is affixed to the vertical support at a proximal end. The support plate has an inner surface defining a first central opening. The resin vessel is supported above the support plate and has an inner edges surrounding a second central opening. The resin vessel includes a transparent sheet that closes the second central opening. The fluid spill containment vessel is supported below the support plate and includes a transparent window. The light engine is supported below the fluid spill containment vessel. The first central opening, the second central opening, and the window laterally overlap to provide an optical path whereby the light engine can project light upwardly to a build plane in the resin vessel.

    Abstract: A three dimensional printing system includes a support plate, a resin vessel, and one or more mechanical features. The support plate includes a ridge surrounding a first central opening. The resin vessel includes a vessel body defining an inner edge surrounding a second central opening and a transparent sheet that closes the central opening to define a lower bound for a body of resin to be contained within the resin vessel. The one or more mechanical features are configured to align and secure the resin vessel relative to the support plate whereby the ridge engages a lower surface of the transparent sheet to tension the transparent sheet and the ridge is laterally recessed inwardly relative to the inner edge of the vessel body.

    Abstract: A three dimensional printing system includes a vertical support, a support plate, a resin vessel, a resin handling module, a latch, and an interface mechanism. The support plate has a proximal end affixed to the vertical support and extends along a first lateral axis to a distal end. The resin vessel is supported by the support plate and includes a vessel body and a transparent sheet. The vessel body has a latch feature formed therein. The resin handling module includes a fluid outlet for dispensing resin into the resin vessel. The interface mechanism is configured to move the latch into engagement with the latch feature and to move the resin handling module from a non-operating position to an operating position whereby the fluid outlet is operably positioned over a portion of the resin vessel.

    Abstract: A three dimensional printing system includes a vertical support, a support plate, a resin vessel, a carriage, and a support fixture. The support plate has a proximal end affixed to the vertical support and extends along a first lateral axis to a distal end. The resin vessel is supported by the support plate and has a rear side that is proximate to the proximal end of the support plate. The resin fluid outlet is supported over the rear side of the resin vessel. The carriage is configured to be translated vertically along the vertical support. A pair of fixture receiving arms extend from the carriage along the first lateral axis from a proximal to a distal end. The fixture receiving arms are spaced apart along a second lateral axis that is perpendicular to the first lateral axis. The support fixture is supported by the two fixture receiving arms.

    Abstract: A three dimensional printing system includes a resin vessel, a light engine, and a fluid spill containment vessel. The resin vessel is for containing resin and has a transparent sheet on a lower side that provides a lower bound for the resin. The light engine is disposed below the resin vessel for projecting pixelated light up through the transparent sheet. The fluid spill containment vessel is disposed between the resin vessel and the light engine to capture resin that spills from the resin vessel. The fluid spill containment vessel includes a housing for containing the spilled resin, a transparent window for allowing the pixelated light to project up through the fluid spill containment vessel and to the transparent sheet, and a fluid barrier wall surrounding at least part of the clear window and configured to reduce an amount of spilled resin required to occlude the pixelated light.

    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.
