Therefore, the mechanical performance of this new technology can have a huge impact on the component’s life. Hence, a fourth axis is added to an existing Fused Filament Fabrication printer and a customized slicing strategy is used. To meet the high demands of mechanical strength, a symmetrical layer stack-up with an alternating variation of the inclination angle is printed onto the fourth axis. Each tube consists of eight layers in total. Starting from α = 15° fiber angle [+15,-15,0,0] S up to α = 75° fiber angle with a 15° angle increase. Each layer has a height of t 1 = 0.125 mm thickness adding up to a tube wall thickness of t w = 1 mm. These tubes are test ed under quasi static axial loading conditions in a universal testing machine. © 2020 The Authors. Published by ELSEVIER B.V.
