RENDER: Regenerated Laser Sinter Powders

选择性激光烧结(SLS)是最重要的热融合添加剂制造(AM)工艺，利用激光将金属或聚合物粉末熔化在彼此之间，尼龙PA12基粉占据了聚合物SLS市场的95%。采用SLS的障碍之一是处理废弃的未烧结粉末的工艺成本和成本，这种粉末被认为是一种微塑料，可能会对水生生物造成环境危害，并积累在河流和土壤中。AM各局在寻找可接收这些废物的堆填区方面遇到困难。废弃的SLS粉末成本很高，利用它的方法主要集中在熔融沉积制造长丝的生产上；虽然可行，但没有一种方法可以在商业上获得，也不能实现封闭的制造系统。Rapid Powders有限公司已经确定并展示了解决这一问题的可行性，并寻求通过赠款资金与其财团合作伙伴Euriscus Ltd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.
