Abstract
As know Polylactic acid (PLA) is a popular and widely used thermoplastic material used in fused filament fabrication (FDM) due to its biodegradability and biocompatibility. As PLA was identified as a brittle material, reinforcement was used to enhance the properties of the PLA. This paper aims to study the effect of using various kenaf volume ratios on the tensile properties of the 2003D PLA filament for 3D printing. The study began by extruding 2003D grade PLA pellet from Ingeo NatureWorks into a single filament extruder machine with an extrusion temperature of 190 °C and a screw rate of 7 rpm. The 90° raster angle of line infill pattern with 100 % infill density were used for the 3D printing specimens. Mechanical test standards such as ASTM D638, was used for tensile testing to analyse the quality of the extruded PLA single filament. As result, the with kenaf fibre loading of 15 % shows the optimum tensile properties among the filler loading, hence it is proven that the tensile properties of the was indeed being enhanced by the additional of the kenaf fibre as reinforcement.
