Abstract: A three dimensional printer includes a vessel, a light engine, a fixture, a movement mechanism, a sensor, and a controller. The vessel is for containing a liquid photocurable resin and includes a transparent sheet defining a lower surface through which the resin can be illuminated. The light engine is disposed and configured to selectively illuminate the resin through the transparent sheet. The fixture is for supporting a three dimensional article of manufacture having a lower face immersed in the resin in facing relation with the transparent sheet. The movement mechanism is configured for controllably translating the fixture to adjust a vertical height of the lower face above the transparent sheet. The sensor is configured to monitor a transient displacement of the transparent sheet during the translation.

Abstract: A three-dimensional printing system includes a print engine, a storage subsystem, and a controller. The print engine includes a resin vessel having a lower side with a transparent sheet, a light engine that defines a build field above the transparent sheet, and a motorized carriage for holding a support tray with a lower surface above the resin vessel. The storage subsystem is configured to store support trays. The controller is configured to: receive a build order including a plurality of incoming files individually defining a three-dimensional article to be fabricated, process and determine breakage-related risk factors for the processed files, define a build plan for at least some of the plurality of processed files based at least partly upon the determined risk factors, and operate the print engine and the storage subsystem to build and store three-dimensional articles according to the defined build plan.

Abstract: A system for manufacturing a three-dimensional article includes a resin vessel, a light engine, a support scaffold, and a positioning actuator. The resin vessel includes an opening closed by a transparent sheet with opposed upper and lower surfaces. The light engine is disposed below the transparent sheet and is configured to transmit or project radiation up through the transparent sheet for selectively curing layers of the resin over a build plane. The support scaffold includes at least one ridge having an upper surface that contacts the lower surface of the transparent sheet to reduce an unsupported width. At a first lateral position the scaffold blocks the radiation from reaching a first blocked region of the build plane. The positioning actuator is configured to laterally move the scaffold from the first position to a second position to allow radiation to reach the first blocked region of the build plane.

Abstract: A three dimensional printing system includes a print engine, a storage system, and a controller. The controller is configured to (1) receive a build order defining a plurality of three dimensional articles to be manufactured, (2) allocate partitions for receiving the plurality of the three dimensional articles within the storage system, (3) operate the print engine to fabricate the three dimensional articles, and (4) transfer the three dimensional articles to the partitions as they are built.
