Abstract

The main benefits of using additive manufacturing (AM) processes are in the ability to manufacture components with a high degree of geometric complexity without this leading to a considerable increase in the time and the final cost of the part when compared to traditional manufacturing methods. In this way, the designer has more freedom to materialize structures inside the component, recesses and freeform surfaces without the need for additional processes, molds or specific tooling. In addition, the AM processes associated with mathematical methods such as Topological Optimization allow the fabrication of components with the topology (distribution of one or more materials in the part domain) and the properties of one or more materials of a given functional component to the detriment of a specific objective and its constraints. This project aims to implement a overhang angle constraint for additive manufacturing to help designers avoid the use of material to works as support in additive manufacturing. (AU)
