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.
