Abstract: Systems and methods for the dispensing of liquid, and automated layering of liquid hydrogel patterns are disclosed. In some embodiments, the systems and methods described herein may utilize a bioprinter having a brush that is configured to pattern a collagen layer. In some embodiments, the bioprinter may be used to make layered bioprinted materials. In some embodiments, the systems and methods described herein may include a bioprinter having an atomizer needle that is configured to dispense liquid in an automated way. In some embodiments, the disclosed systems and methods may provide modified surfaces upon which materials may be printed using a three-dimensional (3D) bioprinter. In one embodiment, a modified surface may be formed of polydimethylsiloxane (PDMS), silicones and the like.

Abstract: Disclosed is a bioextruder assembly capable of “retro-fit” an existing three-dimensional (3D) printer such that it is capable of printing biomaterials. The bioextruder assembly may be modular, self-contained, and configured as “plug-and-play” unit. In some embodiments, the bioextruder assembly may be configured for use in zero-gravity environments such as space and configured to engage with existing 3D printers in space. In some embodiments the bioextruder assembly includes an extruder configured to extrude bio-materials stored in a syringe that is coupled to the extruder, and a converter. The converter may include an electromechanical coupling component that couples the converter to a three-dimensional printer system, and a motor configured to actuate the extrusion of bio-materials stored in the syringe based on signals received from the three-dimensional printing system via the electromechanical coupling component.

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: 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).
