Abstract

Wood-plastic composites (WPCs), combined with wood particles as filler and plastic as matrix material, is a kind of sustainable (if recyclable polymer is used) and environment-friendly material. Additive manufacturing (AM), as its high-precision and cost-saving characteristics, provides the possibility for the formation of WPCs with complex structure. Therefore, this study systematically described the techniques and recent progress of WPCs formed by AM, including the preparation of original WPCs, preprocessing of WPCs used in AM, several available AM processes for WPCs, as well as current applications and prospects. This research is expected to lay the foundation for the high-value application of WPCs.
