RENDER: Regenerated Laser Sinter Powders

选择性激光烧结（SLS）是最重要的热融合增材制造（AM）工艺，利用激光将金属或聚合物粉末层相互熔化，尼龙PA12基粉占据聚合物SLS市场的95%。采用SLS的一个障碍是处理未烧结粉末的成本和处理成本，这些粉末被认为是微塑料，有可能对水生生物造成环境危害，并在河流和土壤中积累。AM各局在寻找可接受这些废物的堆填区方面遇到困难。废弃的SLS粉末代表着巨大的成本，利用它的方法主要集中在生产熔融沉积制造细丝；虽然可行，但没有一种是商业上可用的，也无法实现封闭的制造系统。快速粉末有限公司已经确定并展示了解决这一问题的可行性，并寻求通过拨款资助，与合作伙伴Euriscus有限公司和兰开斯特大学一起建立其技术和商业可行性。

Selective Laser Sintering (SLS) is the most important thermal fusion additive manufacturing (AM) process utilising lasers to melt layers of metal or polymer powder on to each other and Nylon PA12 base powders occupy 95% of the polymer SLS market. One of the barriers to the adoption of SLS is the process cost and cost of disposal of waste un-sintered powder that's considered a microplastic having the potential to cause environmental harm generally to aquatic living organisms and to accumulate in rivers and soils. AM bureaux are experiencing difficulties in finding landfill sites that will accept this waste. Discarded SLS powder represents a significant cost and approaches to utilise it have focused on the production of fused deposition manufacturing filaments; and although feasible, none are commercially available nor enable a closed manufacturing system. Rapid Powders Ltd has identified and shown the feasibility of a solution to this problem and seeks through grant funding to establish its technical and commercial viability together with its consortium partners Euriscus Ltd and Lancaster University.
