Effect of printing parameter on mechanical properties cPLA/Fe2O3 composites using FDM.

Fused Deposition Modelling (FDM) is an additive-manufacturing techniques which used to fabricate thermoplastics. Polylactic acid (PLA) was chosen for this study due to its cost benefits and widely explore due to its biodegradable properties [1], [2], [3]. Due to limited resources to investigate the mechanical properties of CPLA/Fe₂O₃. This paper aimed to study the mechanical properties of CPLA/Fe₂O₃ prepared through 3D printing. The samples were fabricated using Fused Deposition Modelling (FDM) with an addition of powder dispenser as a filler distribution. Different infill densities (100%, 90%, 80%) and different infill patterns (Concentric, Grid, ZigZag) were used as the printing parameters. Tensile testing was conducted to investigate the mechanical properties of CPLA/Fe₂O₃. The tensile strength of CPLA/Fe₂O₃ of 100% infill density was the highest compared to 90% and 80%.
