An extended cost analysis method for complex lightweight aircraft components manufactured with selective laser melting

Abstract Current research has shown that the costs of manufacturing parts by selective laser melting (SLM) process are higher than production using conventional techniques. This paper aims to extend a cost analysis method for metallic based on CAD data including hot isostatic pressing as heat treatment in SLM technique. The proposed includes all pre- and post-processing steps linked allows determination aggregated per part. A case study consisting lightweight aircraft wing rib with Internet Things capabilities whose weight is around 96% less be necessary other studies presented. results show main driver build cost, which major contributor machining followed material cost. can applied components within an box.
