Presentation Title Spatial Architecture of Copper Fillers in Additively Manufactured PLA-matrix Composite

Abstract Scope The fused deposition modeling (FDM) process was utilized as a platform to customize the spatial architecture of copper fillers in the 3-D structure of the PLA matrix. Prior to the extrusion process in FDM, the surface of the PLA filament was knurled to make grooves, which were selectively filled with copper powders. Monolayer samples were manufactured with a layer height of 0.6 mm, and a width of 25 mm. The PMC was devised to have a 20 mm length at the middle of samples with 90 mm length. The samples were subjected to uniaxial tensile tests to assess their fracture energy. For all samples, the fracture was brittle at the interface between the layers. The samples with PMC sections showed inferior fracture strength in comparison with pure PLA samples. This result was attributed to the formation of voids at the interface between copper powders and the PLA matrix.
