The space industry has developed an interest in converting some of its production from traditional manufacturing to metal additive manufacturing. This may prove beneficial to the space industry due to their generally low production volumes, and their need to minimize product mass. Unfortunately, the transition from traditional to additive manufacturing can be difficult, and requires designers to take heed of a new set of constraints. To aid the designers this thesis project has aimed to create a software which automatically alters the geometry of 3D STL-models. These alterations reduce the need for support structures, resulting in an easier to print model. A prototype software was created which can handle simple geometries, but struggles when the model complexity increases. Two main problems were encountered: difficulty to handle overhang surfaces that point directly down, and unintended software behavior which caused issues in high complexity models. These issues could not be resolved during the course of this project, but could likely be overcome in the future. Thus, this thesis project resulted in the creation of a proof of concept, in the form of a software prototype.
