Abstract

The main purpose of this study is to investigate the effect of various loadings of maleic anhydride grafted polypropylene (MAPP) on mechanical, physical, and morphological characteristics of filament and 3D printed wood dust/recycled polypropylene composite (r-WoPPc) specimens. The r-WoPPc filaments were produced with MAPP loadings of 0%, 1%, 3%, and 5%, respectively. Wood dust, MAPP and recycled polypropylene were hot pressed, crushed and extruded using single extruder to produced r-WoPPc filament and printed into 3D printed specimens. R-WoPPc filament morphology was examined, and the 3D printed specimens were studied on tensile strength, flexural strength, water absorption properties and morphological. The results indicate that among all MAPP loadings, the addition of 5% MAPP into r-WoPPc was the best. Compared with before MAPP addition, it was enhanced by 39.468%. The MAPP reinforced the bond between recycled wood dust and recycled polypropylene matrix, therefore improved the strength of r-WoPPc.
