    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.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: A support fixture is provided for forming a three dimensional article of manufacture onto a lower build surface thereof. The formation occurs in a resin vessel containing photocurable resin. The resin vessel includes a transparent sheet that forms a lower bound for the resin. The support fixture includes a lower planar portion, an upper portion, and a side wall coupling the lower planar portion to the upper portion. The lower planar portion defines a dense array of small openings that minimize a fluid drag of lateral resin motion when the lower build surface is proximate to the transparent sheet. The upper portion is for providing alignment and support within the three dimensional printing system. A plurality of large openings formed along the side wall that individually have a cross sectional area that is equal to a combined cross sectional area of a plurality of the small openings.

    摘要: The invention is directed to systems and methods for detailing a graphical 3D solid model displayed to a user. An example system includes a graphical user interface device (e.g., joystick, keyboard, stylus, roller ball, touch screen, tablet, etc.) configured to receive input from a user and transmit the input to a computer including a Central Processing Unit (CPU) and/or a Graphics Processing Unit (GPU), a memory for use with the computer, and a video display configured to graphically display the detailed 3D solid model to the user.
