Selective inhibition sintering: Advancements & systematic research approaches for the process development

SIS system is a new emerging Rapid Prototyping (RP) technique. Commercial rapid prototyping process like STL and electron beam melting produces the parts by infusion of laser energy. But in SIS process, parts are built by fusion of polymer powder particles in the part’s body and preventing joining powder particles at the part boundary. Fundamental of SIS processes were investigated by several researchers. The polymer based SIS process has numerous advantages over the existing RP techniques. This paper discusses the major factor encounter in the development of polymer based SIS process, material selection, optimization of various input parameters, software and hardware design and development, fanatical path generation, application of response surface methodology which has led to optimum performance, factors affecting surface quality, strength of part and dimensional accuracy. © Research India Publications.
