Abstract

The advancement of technology in 3D printing has made possible a change in structural engineering. In terms of construction, new geometries that were previously either solid or had a high layer thickness can be used to fill structural designs, thus providing energy, cost and mass savings.
In this final degree project, it is intended to show a wide range of designs applicable to geometries with structural functions, as well as their manufacture using the Fused Deposition Modeling (FDM) technique in Additive Manufacturing with the Ultem 9085 material. In addition It is equipped with comparative graphs to be able to decide the best geometry according to the application to which it is intended.
To achieve the main objective of the study, a search for recent scientific research will be carried out in the field of geometry design and tests thereof using different Additive Manufacturing methods. Next, it will be shown how the studied designs have been created and the programs used to create structural cubes that contain the geometries that will be exposed. Once designed, the cubes will be prepared for manufacturing using FDM in two styles: Solid and Sparse, in such a way that more material is saved. Finally, a post-processing of most of the printed cubes will be carried out, where the support material generated in the printing will be removed.
From the data extracted from these procedures, the profitability of the geometries can be determined in mechanical terms such as the weight of a geometry or in economic terms with respect to the manufacturing method.
