This thesis explores the mechanical properties of hemp fiber reinforced polylactic acid (PLA) composites. Fused filament fabrication (FFF) was used to compare the performance of three different weight percentages of hemp fiber reinforced PLA against PLA and acrylonitrile butadiene styrene (ABS). It was found that as the weight percentage of hemp increased in PLA, the tensile strength decreased and Young's modulus generally increased. The higher weight percent (5 and 10%) hemp fiber reinforced PLA was found to have a significantly higher Young's modulus than PLA but more research needs to be done to measure other mechanical properties to determine appropriate applications of this plastic composite.Key Words: Plastics, 3D Printing, FDM, Hemp, Sustainabilit
