Abstract
A method comprising receiving a first 3D toolpath defining a fill material curved shell, receiving first 2D toolpaths defining support material flat shells, receiving a second 3D toolpath defining a long fiber composite material curved shell, the long fiber composite material including a filament having a matrix embedding fibers having a length longer than two times a diameter of the filament, actuating a fill material deposition head to trace the first 3D toolpath to deposit the fill material curved shell non-parallel to a printing substrate, actuating a support material deposition head to trace the first 2D toolpaths to deposit support material in a succession of substantially flat shells, and actuating a long fiber deposition head to trace the second 3D toolpath non-parallel to the printing substrate to deposit the long fiber composite material curved shell to enclose at least a portion of the fill material curved shell.
