Abstract:
A method for fabricating a composite part using a 3D printing machine. The method includes forming the part by depositing an alternating sequence of first part layers including rows of filaments made of a first part material and depositing second part layers including rows of filaments made of a second part material, where the second part material is different than the first part material and provides adhesion between the first part layers.
