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.

Abstract: A 3D printing machine for fabricating high performance 3D integrated composite structures, where the machine includes a robot having a base portion, a robot arm and a rotatable connector secured to the arm opposite to the base portion, at least one source of an extrudable material, and an end-effector mounted to the rotatable connector and including at least one extruder module for extruding the extrudable material. The extruder module includes a nozzle assembly for extruding heated material out of the end-effector, and the end-effector is rotatable relative to the structure by the rotatable connector so that the nozzle assembly can be oriented normal to the part in different orientations without significantly changing a pose of the robot.

Abstract: A system for fabricating a composite part using a 3D printing machine. The system includes means for forming the part by depositing consecutive part layers each including rows of filaments made of a part material from the machine, where depositing each part layer includes non-sequentially depositing one set of a plurality of filaments so that a gap is formed between the filaments and then depositing any number of additional sets of filaments so that each adjacent pair of filaments in each additional set of filaments are non-sequentially deposited.

Abstract: A method for fabricating a composite part using a 3D printing machine. The method includes forming a support structure by depositing consecutive support structure layers including rows of filaments made of a support structure material from the machine on a build plate, smoothing out a top surface of the support structure after it is formed, and forming the part by depositing consecutive part layers including rows of filaments made of a part material from the machine on the support structure.
