The Michigan furniture industry produces >150 tons/day of wood-based waste, which can be upcycled into a wood polymer composite (WPC). This study investigates the viability of using furniture waste as a feedstock for 3-D printer filament to produce furniture components. The process involves: grinding/milling board scraps made of both LDF/MDF/LDF and melamine/particleboard/paper impregnated with phenolic resins; pre-mixing wood-based powder with the biopolymer poly lactic acid (PLA), extruding twice through open-source recyclebots to fabricate homogeneous 3-D printable WPC filament, and printing with open source FFF-based 3-D printers. The results indicate there is a significant opportunity for waste-based composite WPCs to be used as 3-D printing filament.
