This paper presents Polymer Matrix Composite (PMC) as feedstock used in Fused Deposition Modeling (FDM) machine. This study discussed the development of a new polymer matrix composite (PMC) material for use in injection molding machine. The material consists of copper powder filled in an acrylonitrile butadiene styrene (ABS), binder and surfactant material. In this study, the effect of copper powder was investigated as a filler material in polymer matrix composite and ABS was chosen as a matrix material. The detailed formulations of mixing ratio with various combinations of the new PMC are investigated experimentally. Based on the result obtained, it was found that, the weight percentage increment of copper filler affected the viscosity, temperature, velocity, melt flow index and surface tension.
