Additive Manufacturing/3D printing of polymer composite has progressed significantly in last 2 years, as has the feasibility of using AM for production parts. With innovations in hardware, print speed has increased by 10x. New printers have come on-line with the capability to print engineering and high performance polymers. To successfully implement AM parts for Aerospace, Oil & Gas and Automotive industries, there is a need for multifunctional composite (composites with high strength and tailored electrical conductivities) and a good understanding of the effect of process parameters on component level properties. In traditional polymer processes. Like injection molding, it has been observed that process parameters such as injection speed, melt temperature, and mold temperature have a significant impact on a part’s electrical conductivity. This presentation will focus on studying the effect of 3D printing (FDM) process parameters on the final part’s properties. The parameters that will be evaluated are extrusion temperature, print speed, bed temperature and nozzle size.
