Additive Manufacturing (AM) has made it possible to manufacture parts whose shape complexity was unfeasible with other traditional methods by depositing material layer-wise. However, this planar layer-wise deposition strategy can be restrictive for the part's properties. However, the anisotropic behaviour can also be embraced and used as an advantage. Therefore, in this thesis a different method is implemented: the Stress-Aligned Printing method (SA), in which print-paths are oriented along the principal stress directions of a part's load case. To implement this method, a new 5-axis 3D printer was developed. An algorithm that converts results from a Topology- and Anistropy- optimization (TAO) to G-code was created. In a case study for a jet engine bracket, an improvement of 156% in ultimate tensile strength was found, while the weight was reduced from 41 g to 20 g. ... Read more
