    Abstract: A 3D printing assembly, system, and method for 3D printing a biomaterial may include a robotic arm end effector and a barrel clamp assembly. The robotic arm end effector is configured to move along one or more axes of movement for 3D printing. The barrel clamp assembly is distally coupled to the robotic arm end effector and includes a barrel clamp arm and a barrel clamp. The barrel clamp arm includes a top end coupled to the robotic arm end effector and a bottom end opposite to the top end. The bottom end is angled forward with respect to the top end. The barrel clamp is coupled to the bottom end of the barrel clamp arm and is configured to receive and clamp against a distal end of a printing syringe barrel for 3D printing.

    Abstract: Systems and methods for a robotic fabrication and assembly platform providing a plurality of printable materials for fabrication of a three-dimensional object are provided. A method includes activating a pneumatic actuator to extend a quick-change turret from a pneumatic seal. The method may insert a plurality of barrels into the quick-change turret. The method may also align one of the plurality of barrels with a pneumatic seal in the quick-change turret. The method may also disengage the pneumatic actuator to seat the aligned barrel onto the pneumatic seal and print a three-dimensional object. The method may further halt the printing of the three-dimensional object prior to completion and engage the pneumatic actuator to extend the quick-change turret from the pneumatic seal.

    Abstract: A 3D printing tool and assembly for dispensing multiple materials includes a barrel holder assembly having at least two barrel orifices extending from a top end of the barrel holder assembly through to a bottom end of the barrel holder assembly, where at least one of the at least two barrel orifices is oriented at an angle from the vertical. A method for operating the 3D printing tool includes positioning a first material distribution barrel within a first barrel orifice, where a first barrel tip is disposed at a first end of the first material distribution barrel. The method further includes dispensing building material from the first material distribution barrel when the first material distribution barrel is substantially vertically oriented and a second material distribution barrel is oriented at an angle from the vertical.
