Mechanical Properties of Cellular Structures with Schwartz Primitive Topology

Abstract : Cellular structures with triply periodic minimal surface (TPMS) topology are studied in current research work. Previously, it was shown that materials with TPMS topology have a potential as a lightweight material in energy-absorbing systems that can be used in various applications such as protective layer landing pods of spacecraft. In this work Schwartz primitive structure was chosen to study the influence of scale factor, unit number on mechanical properties. Samples were made by selective laser sintering process of polyamide powder and tested on Walter+bai ag LFM − 400 kN machine.
