Abstract: A three dimensional printing system includes a build module, a powder storage module, a powder transport conduit, a vertical powder transport module, and a powder layering apparatus. The build module has a lateral side. The powder storage module is located at least partially below the build module. The powder storage module has a lateral side and defines an internal volume for holding powder. The powder transport conduit transports the powder to a lateral location that is laterally offset from the lateral side of the powder storage module. The vertical powder transport module is laterally offset from the lateral sides of the build module and the powder storage module and includes a lower end for receiving powder from the lateral location and an upper end having a laterally extending powder outlet. The powder layering apparatus receives the powder from the laterally extending powder outlet.

Abstract: A custom device and method for fabricating the custom device includes marking a body with reference points and/or other indicators. Multiple images of the body from multiple angles are then obtained. The images are used to determine the contours of the body and the other markings are located and used to design a brace having an inner surface that corresponds to the contours of the body. The custom modular brace is fabricated as multiple pieces that are releasably coupled together and sequentially removed as the patient heals.

Abstract: In an aspect of the disclosure, a three dimensional (3D) printing system includes a printhead and an ink supply subsystem. The printhead is for ejecting drops of phase change ink to define a three dimensional article of manufacture. The ink supply subsystem includes an ink tube, a helical resistor, a return conductor, and an outer tube. The ink tube has an inside surface for contacting and transporting the phase change ink and an outer tubular surface. The resistor is helically wound around the outer tubular surface of the ink tube. The return conductor is helically wound around the resistor and has a resistance that is lower than that of the resistor. The outer tube surrounds and protects the resistor and the return conductor and provides insulation to the heated ink transport component.

Abstract: A three dimensional printing system includes a resin vessel, a light engine, a movement mechanism, a fixture, and a controller. The resin vessel is for containing a photocurable resin and has a lower portion with a transparent sheet. The light engine is configured to selectively project radiation up through the transparent sheet and over a build plane. The fixture is coupled to the movement mechanism and has a lower face that faces the transparent sheet. The controller is configured to operate the light engine to solidify a particle trapping sheet proximate to the build plane thereby trapping particles that extend upwardly from the transparent sheet into the build plane.

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.

Abstract: Polymerizable liquids are described herein which, in some embodiments, can produce 3D printed articles of high resolution and desirable mechanical properties. In one aspect, a polymerizable liquid comprises an acrylate component, a polymeric additive, and a monomeric curing agent, wherein the acrylate component and monomeric curing agent are copolymerizable upon exposure to light. In being copolymerizable, the acrylate component and monomeric curing agent can form a copolymer. As described father herein, the monomeric curing agent can enable further reaction of the copolymer with one or more crosslinking species to link the copolymer with one more polymeric networks.

Abstract: A system for fabricating a three-dimensional article includes a fluid supply with binding agent, a printhead, a powder dispenser, and a controller. The fluid supply is for containing a binding agent. The controller is configured to (a) operate the fluid supply and/or the printhead to elevate a temperature of the binding agent to above 25 degrees Celsius, (b) operate the dispenser to dispose a layer of the powder at a build plane, (c) scan and operate the printhead to selectively jet the binding agent onto the layer of powder to bind a layer of the three-dimensional article, and (d) repeat operating the dispenser and scanning and operating the printhead to complete fabrication of the article. Jetting or not jetting the binding agent includes individually operating drop ejectors of the printhead using a voltage waveform. The waveform can include one or more of a non-ejecting pulse and an ejecting pulse.

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: Thermoplastic 3D objects are printed directly onto permeable materials with a high strength bond. The 3D object can be attached to the permeable material at one side where the bottom layer of the 3D object can be attached to the permeable material or alternatively, at an internal layer where portions of the 3D object are on opposite sides of the permeable material. In order to improve the adhesion of the 3D object to the permeable material, the bonding layer of the liquid thermoplastic material that is printed directly onto the permeable material can be deposited at modified 3D printer settings that can include a hotter than normal material deposition temperature. Additional build layers of the liquid thermoplastic material are printed on the bonding layer to complete the 3D objects.
