Abstract: The present invention relates to a three-dimensional bioprinter for printing and/or patterning a single type or multiple types of cells into different geometrical arrangements and other three-dimensional structures, such as tissues. The bioprinter comprises multiple heads that can each be loaded with a different cartridge containing a biomaterial or biological material such as cells in a solution or cells in a hydrogel. Each bioprinter head and cartridge has the ability to heat or cool using Peltier technology. The bioprinter also has the ability to auto calibrate on a bed plate configured to accept a petri dish or microtiter plate.

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.

Abstract: A method of manufacturing a three dimensional article includes forming the three-dimensional article with three-dimensional printing, processing the three-dimensional article to remove support material ink, illuminating the three-dimensional article with electromagnetic radiation, inspecting the three dimensional article for photoluminescence that is responsive to the illumination, and verifying whether the support material has been sufficiently removed based upon the inspection. The support material ink includes a phosphor component that phosphorescently emits light in response to the illumination.

Abstract: Disclosed are systems and methods for a bioprinter capable of printing an object having biological components. In some embodiments, the bioprinter includes a modular print bed having a recessed area configured to receive a variable insert and a printer head positioned above the modular print bed. In some embodiments, the printer head has a cartridge for receiving and holding a biomaterial, and an extruder configured to extrude biomaterials from the cartridge onto a portion of the variable insert. The variable insert may include functional elements (e.g., heating, cooling, photocuring) and/or receiving elements (e.g., well plates).

Abstract: A three-dimensional printing system for solidifying a photocurable resin in a layer-by-layer manner at a build plane includes a scan module, a transparent plate, a sensor, and a controller. The scan module is configured to scan the light beam along two axes to address the build plane. The transparent plate is positioned in the optical path between the scan module and the build plane. The transparent plate has at least one reflective feature in the optical path. The sensor is mounted above the glass plate and is positioned to receive light reflected from the reflective feature. The controller is configured to operate the scan module to scan the light beam across the build plane, receive a signal from the sensor when the light beam impinges upon the reflective feature, and analyze the signal to verify a proper alignment of the light beam to the build plane.

Abstract: In one aspect, inks for use with a three-dimensional (3D) printing system are described herein. In some embodiments, an ink described herein comprises 10-70 wt. % cyclopolymerizable monomer, based on the total weight of the ink. The cyclopolymerizable monomer comprises a first ethenyl or ethynyl moiety and a second ethenyl or ethynyl moiety. Additionally, the α-carbon of the first ethenyl or ethynyl moiety and the α-carbon of the second ethenyl or ethynyl moiety have a 1,5-, 1,6-, 1,7-, or 1,8-relationship.

Abstract: A three dimensional printing system for manufacturing a three dimensional article includes a movement mechanism, a support tray, a resin vessel, a light engine, a sensor, and a controller. The support tray is mounted to the movement mechanism and has a lower surface for supporting the three dimensional article. The resin vessel includes a transparent sheet defining a lower bound for resin contained therein. The light engine projects pixelated light through the transparent sheet and to a build plane. The controller is configured to (a) receive a start indication for a build process, (b) operate the sensor, (c) determine if polymerized build material is in a flag region from the sensor signal, and (d) if polymerized build material is determined to be in the flag region, halt the build process.

Abstract: A system for manufacturing a three-dimensional article includes a resin vessel, a vertical movement mechanism, and a light engine. The resin vessel includes a lower opening closed by a transparent sheet. The vertical movement mechanism is for positioning a support tray which supports the three-dimensional article. The light engine is disposed below the transparent sheet and is configured to selectively harden layers of resin over a build plane above the transparent sheet. The light engine includes a light bar coupled to a lateral movement mechanism. The light bar includes an array of light emitting devices and a device for impinging upon the transparent sheet. The impingement maintains a proper operating distance H between the transparent sheet and the build plane.

Abstract: A three-dimensional printing system includes a build vessel, a plate, a vertical movement mechanism coupled to the plate, a powder coater, an energy source, and a controller. The build vessel includes one or a plurality of vertical chamber walls. The vertical chamber wall(s) laterally enclose a build chamber and have inward facing surfaces that collectively define a lateral extent or width of the build chamber. The build vessel includes a lip that defines an upper surface of the build vessel. The lip extends inwardly from the inward facing surfaces to define an opening having a lateral extent that is smaller than the lateral extent of the build chamber. The plate has an upper surface and a lateral extent that is larger than the lateral extent of the opening. The plate laterally overlaps with the lip.
