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.
