Patent number: 11325314Abstract: 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.Type: GrantFiled: December 18, 2019Date of Patent: May 10, 2022Assignee: 3D Systems, Inc.Inventor: Winthrop Childers

Patent number: 11059219Abstract: 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.Type: GrantFiled: July 26, 2019Date of Patent: July 13, 2021Assignee: 3D Systems, Inc.Inventor: Winthrop Childers

Patent number: 10800153Abstract: A three-dimensional object may be generated. First and second agent distributors may be to respectively selectively deliver a binder agent and a coalescing agent onto portions of a layer of build material. A controller may be to control the first and second agent distributors to respectively selectively deliver the binder agent and the coalescing agent onto respective first and second portions of the layer in patterns derived from data representing a slice of the three-dimensional object to be generated.

Patent number: 10576685Abstract: A three-dimensional (3D) printing method includes applying a build material, including: a plurality of first reactive particles; a plurality of second reactive particles, the first and second reactive particles to react with each other upon contact there with; and a coating on i) the plurality of first reactive particles; or ii) the plurality of second reactive particles; or iii) both i) and ii). The coating is to isolate the plurality of first reactive from the plurality of second reactive particles. A fluid is selectively applied on a portion of the build material, the fluid disrupting the coating on the portion of the build material to render the first and second reactive particles in the portion of the build material in contact with each other. The contact initiates mutual reacting and fusing between the first and second reactive particles.Type: GrantFiled: April 30, 2015Date of Patent: March 3, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ali Emamjomeh, Keshava A.
