Selective Separation Shaping (SSS) – Large-Scale Fabrication Potentials

Selective Separating Shaping is a new additive manufacturing technique which is capable of processing polymeric, metallic, ceramic and composites including cementitious materials. In earlier experiments the capabilities of SSS in making metallic and ceramic parts have been demonstrated. The focus of the research reported in this paper has been on exploration of capabilities of SSS for creation of large-scale cementitious composite parts. A prototype machine has been used to create specimens made of regular construction cement (lime based), Sorel cement (magnesia based) and gypsum based composites. The fabrication results, surface quality and flexural strength for these experiments are presented.
