Mechanical characterization and numerical modeling of laser-sintered TPE lattice structures

Abstract Additive Manufacturing provides the opportunity to produce tailored and complex structures economically. The use of lattice in combination with a thermoplastic elastomer enables generation configurable properties by varying cell parameters. Since there is only little knowledge about producibility made TPE laser sintering process resulting mechanical properties, different kinds are investigated within this work. type, size strut thickness these varied analyzed. Within experimental characterization Dodecahedron-cell static cyclic compression tests sandwich focused. material exhibits hyperelastic plastic also Mullins-Effect. For later design real structures, numerical methods helps reduce time costs. preceding investigations used develop concept for modeling structures. Graphic abstract
