Abstract
Polylactic acid (PLA) filament is affordable yet can be consider costly for research purposes. A lot of prototype need to be printed for testing or evaluation in a project. This study focusing on recyclability of PLA that widely used in 3D-printing. A filament extruder had been fabricated to extrude the recycled PLA filament. A set of five specimens was printed from each PLA and recycled PLA filament using fused deposition modelling (FDM) 3D printing process. The objective of this study is to investigate the mechanical properties of 3D-printed part using original PLA and recycled PLA filament. The experiment using ASTM D638 type IV standard of procedure to evaluate the tensile strength properties. Comparison is made on the PLA of original and recycled to see if the recycled PLA having large difference or not. The final result shows that the recycled PLA specimens differ within 3%-30% in term of tensile properties. The obtained result shows that recycled PLA filament can be used in 3D-printing process.
