The objective of this work is to implement a constraint in a topology optimization problem, in order to produce designs that are ready to be 3D printed without the need of supportive structures. There are several motivations to study this, some of the most important ones are to make the 3D printing process shorter and to avoid the need of post printing processes like removing the supportive structure. These together make the whole process more economical. The basis of the project are  and , and this work will try to replicate their findings. In order to prevent future researchers to commit the same mistakes as we did in the beginning and save them time, we will share some of the main problems that were found during the research process. That is why we have divided the research in two phases: phase one, just trying to detect the boundary elements of fixed final designs, and phase two, implementing the overhang constraint in the topology optimization code.
