摘要：

Biomass-derived polymers have been rapidly developed for alleviating excessive fossil-fuel-based plastic consumption, as green manufacturing is required due to many environmental issues. Here, using a recently developed biopolymer, bio-based polycarbonate (bio PC), we demonstrated the processability of filament-feedstock extrusion and extrusion-type 3D printing. Under a set of optimal process conditions, the as-printed bio PC products showed superior tensile strength compared to other commercial polymers. We also confirmed the environmentally friendly characteristics of the thermoplastic processes of bio PC by measuring hazardous emissions during 3D printing. Finally, considering sterilization of the as-printed consumer products, we tested the resistive properties of bio PC parts against heat and UV. Collectively, the good 3D printability, low gas and particle emission, and decent durability of the bio PC material indicate great potential applications for indoor home manufacturing of various consumer products.
