The paper is presenting studies and experiments on 3D printing of composite parts. The novelty of the printing process used is that the parts are printed using continuous reinforced fibers in a plastic matrix. Printing with continuous fiber reinforcement offers a few advantages compared to conventional processes as following: short manufacturing time, high strength, and low part weight. The internal structure of the model can be designed according to the part loads and the continuous fiber is disposed only in the layers where it is necessary. In this experimental research, an industrial part was studied and different possibilities of designing the internal structure were analyzed.
