Additive Design & Technologies. Study and design of the necessary supports used for Additive Manufacturing processes through a new innovative methodology, which exploits topology optimization in order to reduce the material used, to make supports, and component deformations due to thermal stress and to improve in terms of timing the process execution. Additive Manufacturing (AM) is a process of building parts by joining material layer by layer from a three-dimensional CAD file, as opposed to subtractive manufacturing techniques (such as turning, milling and so on) . One of the principles of the AM is that the model generated as CAD can be produced bypassing the process planning.
