Comprehensive characterization of 3D‐printed bamboo/poly(lactic acid) bio composites

Abstract

AbstractIn recent years, the use of additive manufacturing technologies especially fused deposition modeling (FDM), 3D printing, have been raised popularity. Poly(lactic acid) (PLA) is one of the most widely used materials in FDM because it is suitable for biodegradation due to environmental problems. Therefore, to improve the properties of PLA and extend its lifespan, the material to be added to its structure must be of natural origin. In this study, mechanical, thermal, thermo‐mechanical, tribological, and morphological properties of composite materials manufactured using bamboo filled PLA filament by FDM method were investigated. The thermal properties of the samples were investigated by differential scanning calorimeter analysis, thermomechanical properties by dynamic mechanical thermal analysis, mechanical properties by tensile and three‐point bending test, and surface hardness by Shore D test. Since there are few studies in the literature examining the effects of 3D printing parameters on tribological properties, in this study, various layer thicknesses, top/bottom pattern, specimen face, and build plate surface type on the wear behavior were examined. Worn surfaces and fractured surfaces were investigated by SEM.
