Abstract

The goal of this research was to investigate the effect of MAPE as a compatibilizer on the morphological, mechanical, and physical properties of 3D printing filaments made from wood dust and recycled polypropylene (R-WoPPc). Four R-WoPPc filaments with MAPE loadings of 0%, 1%, 3%, and 5% by weight were produced and printed into 3D specimens. The morphology of R-WoPPc filament was studied, as well as the properties of printed specimens such as tensile properties, flexural properties, microstructure, and physical properties. The results revealed that 1% MAPE in R-WoPPc yielded the highest performance for the material's microstructure, tensile strength, water absorption, and flexural strength. Tensile strength improved by 74.07% compared to without MAPE addition and was the highest among all MAPE loadings. The MAPE strengthened the adhesion between recycled wood dust and recycled polypropylene matrix, resulting in improved R-WoPPc performance. Pure addition of filler and matrix causing pure properties or strength.
