摘要： A three-dimensional (3D) printing system includes a print engine chassis, a build box, a vertical movement mechanism, a powder dispensing module, a consolidation module, and a controller. The print engine chassis defines a build chamber configured to receive and support the build box. The build box includes a build plate upon which the 3D article is fabricated. The vertical movement mechanism includes a plurality of actuators configured to collectively provide precise positioning of the build plate. The controller is configured to (1) operate the vertical movement mechanism including operating the plurality of actuators to position an upper surface of the 3D article generally proximate and parallel to a build plane, (2) operate the powder dispensing module to dispense a new layer of powder over the upper surface, and (3) operate the consolidation module to selectively consolidate the new layer of powder.

摘要： A three-dimensional printing system for fabricating a three-dimensional article includes a motorized build platform, a dispensing module, a pulsed light source, an imaging module, a movement mechanism, and a controller. The imaging module receives radiation from the pulsed light source and includes a two-dimensional mirror array. The movement mechanism imparts lateral motion between the imaging module and the build platform. The controller is configured to operate the motorized build platform and the dispensing module to form a layer of build material at a build plane, operate the movement mechanism to laterally scan the imaging module over the build plane, operate the pulsed light source to generate a sequence of radiation pulses that illuminate the mirror array, and operate the mirror array to selectively image the build material.

摘要： A three-dimensional (3D) printing system includes a vessel, a coating subsystem, a calibration block, and a controller. The vessel is configured to contain a photocurable resin having a resin upper surface. The coating subsystem includes a coater module including a coater blade, a lateral movement mechanism coupled to the coater module, a sensor mounted to the coater module, and a vertical actuator system. The calibration block has a calibration surface. The controller is configured to operate the lateral movement mechanism to position the coater blade over the calibration block, operate the vertical actuator system to lower the coater blade into engagement with the calibration surface of the calibration block, operate the sensor to measure a distance to the calibration block, and store the distance as indicative of a vertical position of a lower edge of the coater blade.

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.

In some embodiments, an ink described herein comprises up to 80 wt. % oligomeric curable material; up to 80 wt. % monomeric curable material; up to 10 wt. % photoinitiator; up to 1 wt. % non-curable absorber material; and up to 10 wt. % one or more additional components, based on the total weight of the ink, and wherein the total amount of the foregoing components is equal to 100 wt. %. Additionally, the photoinitiator is operable to initiate curing of the oligomeric curable material and/or the monomeric curable material when the photoinitiator is exposed to incident curing radiation having a peak wavelength λ. Moreover, the ink has a penetration depth (Dp), a critical energy (Ec), and a print through depth (DPT) at the wavelength λ of less than or equal to 2×Dp.

摘要： A three-dimensional printing system includes a resin vessel containing resin, an imaging bar, a movement mechanism coupled to the imaging bar, and a controller. The imaging bar includes an arrangement of light emitting devices that selectively emit radiation from an exit surface of the imaging bar to define a build plane in the resin. The exit surface of the imaging bar is preferably less than 10 millimeters from the build plane. The controller is configured to scan the imaging bar along a scan axis and, concurrent with scanning, operate the imaging bar to selectively image a layer of resin at the build plane.

摘要： A system for manufacturing a three-dimensional (3D) article includes a controller. The controller is configured to (A) receive a solid model defining the 3D article having an unsupported (downward facing) surface and (B) define a support structure for the unsupported surface. The support structure includes (1) a lower support beam, (2) a node body, and (3) at least three branches. The node body is defined at an upper end of the lower support beam. The node body has an upper surface that is generally in facing relation with the unsupported surface. The at least three branches extend with a diverging geometry away from the upper surface of the node body and to the unsupported surface. The branches are individually defined by a vertical sequence of contour scan patterns.

摘要： A three-dimensional printing system includes a resin vessel, a build tray, a movement mechanism, a sensor, a light engine, and a controller. The resin vessel is configured to contain photocurable (radiation curable) resin and includes a transparent sheet. The transparent sheet has an upper surface that defines a lower bound for the photocurable resin. The build tray has a lower surface configured to support the 3D article. A lower face is defined by either the build tray or the 3D article. The sensor is configured to output a signal indicative of a vertical position of the transparent sheet. The light engine is configured to image a build plane that is proximate to the upper surface of the transparent sheet. The controller is configured to control motion of the movement mechanism based upon analyzing a signal from the sensor including determining a maximum deflection of the transparent sheet during motion.
