Abstract

Polycarbonate (PC) is emerging as one of the fastest-growing engineering plastics, but its potential for its application in a circular economy requires further investigation. This research explores the technical feasibility, carbon footprint, and economic impact of recycling injection moulding PC waste via fused deposition modelling (FDM) at a biotechnology manufacturer plant in the UK. The results show that recycling moulded PC scrap using FDM yields 3D printed parts with 88–98 % of virgin PC mechanical properties, produces nearly 70 % less carbon footprint, and saves up to 88 % of costs than utilizing virgin PC material.

通过增材制造回收聚碳酸酯的可持续性

聚碳酸酯（PC）正在成为发展最快的工程塑料之一，但其在循环经济中的应用潜力有待进一步研究。本研究探讨了技术可行性，碳足迹，并通过熔融沉积建模（FDM）在英国的生物技术制造商工厂回收注塑PC废料的经济影响。结果表明，使用FDM回收成型PC废料产生的3D打印部件具有原始PC机械性能的88 - 98%，产生的碳足迹减少了近70%，并且比使用原始PC材料节省了高达88%的成本。
