Structural stability of Polylactide rope drums with a hybrid Gyroid-spokes infill structure, manufactured through fused filament fabrication

Abstract: Additive manufacturing (AM) offers greater design freedom than conventional manufacturing processes. AM allows for components with complex infill structures of e. g. triply periodic-minimal surfaces (TPMS) that lead to significant weight reduction. Nevertheless, AM is mainly used in specialised engineering branches such as aerospace and medical engineering. This is due to high system cost and the high energy costs of the machines used, which utilise selective laser sintering (SLS), laser powder bed fusion (LPBF), or stereolithography (SLA). Fused filament fabrication (FFF) can offer cheaper and more energy-efficient machines. A series of tensile tests with FFF rope drum bodies made from polylactide (PLA) aims to investigate the stability of FFF machine elements. The test specimens possess a novel, hybrid infill structure comprised of straight spokes and a TPMS-gyroid surface. Compared to previous investigations, the specific breaking force – relative to the test specimens’ weight –.... https://www.bibliothek.tu-chemnitz.de/ojs/index.php/innoTRAC/article/view/516
