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.
