Biopolymers in additive manufacturing

Additive manufacturing provides the on-demand fabrication of tailor-made polymeric products. Despite the promise it holds, serious environmental challenges remain related to materials and energy use. A circular pathway requires the utilization of 3D printing filaments, inks, and resins based on renewable resources, which are biodegradable or otherwise recyclable after use. In this chapter, recent advances in both natural and synthesized biopolymers used in additive manufacturing are addressed, focusing on material design, printability, and potential applications.
