Abstract
Poly (lactic acid) (PLA) is amongst the preferable materials used in 3D printing
because of its unique properties such as good appearance, higher transparency, less
toxicity and low thermal expansion that help reduce the internal stresses caused during
cooling. However, PLA is brittle and has low toughness and thermal resistance that
affect its printability and restricts its industrial applications. Therefore, in this study,
PLA is blending with various content of Polybutylene adipate terephthalate (PBAT) at
20, 50 and 80 wt.% in a twin-screw extruder. The tensile, thermal, morphology and
rheological behaviour of PLA/PBAT filaments were characterized. Then, the most
promising and balance properties of PLA/PBAT (80 wt.% PLA: 20 wt.% PBAT) was
subjected to reinforced with 10 wt.% Empty Fruit Bunch (EFB) and the biodegradation
of PLA/PBAT and PLA/PBAT/EFB were investigated. After that, the selected
PLA/PBAT and PLA/PBAT/EFB filaments were printed using a Fused Deposition
Modeling (FDM) 3D printing machine and the performance of PLA/PBAT and
PLA/PBAT/EFB were compare between the 3D printing and compression moulding
techniques. The physical, mechanical, thermal and morphology properties of
PLA/PBAT and PLA/PBAT/EFB were characterized.
