Abstract
A method for fabricating a composite part using a 3D printing machine. The method includes forming the part by depositing a plurality of part layers in a consecutive manner on top of each other where each layer is deposited by laying down rows of filaments made of a thermoplastic composite material. Reinforcing Z-pins are then inserted through the part layers to provide reinforcement of the part in the Z-direction. A plurality of additional part layers are deposited in a consecutive manner on top of each other on the part layers including the reinforcing Z-pins where each additional part layer is also deposited by laying down rows of filaments made of a thermoplastic composite material. Reinforcing Z-pins are also inserted through the additional part layers to provide reinforcement of the part in the Z-direction.
