Abstract
A printing machine for fabricating high performance 3D integrated composite structures. The machine includes a robot having a base portion, a robot arm and an end joint secured to the arm opposite to the base portion, at least one source of an extrudable material, and an end-effector mounted to the end joint. The end-effector includes at least one extruder module for extruding the extrudable material and a rotary assembly, where the extruder module includes a nozzle assembly for extruding heated material out of the end-effector. The extruder module is mounted to the rotary assembly and the rotary assembly is rotatable so as to rotate the nozzle assembly relative to the part without rotating the end-effector.
