Process Manufacture Rotor Radial Turbo-expander for Small Scale Organic Rankine Cycles Using Selective Laser Melting Machine

This paper discusses the manufacturing process of rotor radial turbo-expanders for small Organic Rankine Cycle systems using additive manufacturing machine Selective Laser Melting (SLM) machine. The process manufacturing consists of data preparation, build job process, and process finishing product. Data preparations are include material preparations, build data preparation using software 3D design Solidworks, support management with software magics and additive manufacturing software with Autofab for build job process on SLM machine. The results shows rotor with material Aluminum Silicon Powder (AlSi) can be made with either the appropriate geometry design within 5 hours with total cost for the whole processing is up to 11 milion IDR.
