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.

选择性激光烧结（SLS）是使用激光融化金属或聚合物粉末融化的最重要的热融合添加剂制造（AM）工艺，而尼龙PA12碱基粉末占多聚合物SLS市场的95％。采用SLS的障碍之一是处理不插入式粉末的过程成本和处置成本，该粉末被认为是一种微型塑料，其潜力通常会对水生生物造成环境伤害，并积累在河流和土壤中。 AM Autreaux在寻找可以接受这种浪费的垃圾填埋场时遇到困难。丢弃的SLS粉末代表了一笔巨大的成本，并且使用它的方法是融合沉积制造丝的生产；尽管可行，但没有一个商业可用，也不可以启用封闭的制造系统。 Rapid Powders Ltd已确定并证明了解决此问题的可行性，并通过资金与其财团合作伙伴Euriscus Ltd和Lancaster University寻求资金来建立其技术和商业可行性。
