Abstract

The mechanical strength and surface quality of 3D-printed polymer composites depend much on the optimization of Fused Deposition Modeling (FDM) parameters. The influence of alumina content on the tensile strength, ductility and surface roughness of polylactic acid (PLA) composites reinforced with alumina (Al2O3) is investigated in this work. The PLA-Alumina composites were made using an FDM printer have mechanical qualities according to ASTM criteria. The finish quality was assessed by means of surface roughness measures. Tensile strength and surface finish are found to be much improved by alumina addition, therefore rendering the material
more appropriate for technical use. The results offer understanding of how FDM process factors may be used to customize the mechanical performance and aesthetic quality of PLA-based composites for various industrial uses
