"SKIN"SKIN - IMPROVEMENT OF THE PERFORMANCE OF MATERIALS PROCESSED WITH ADDITIVE MANUFACTURE THROUGH POST-PROCESSES DESCRIPTIONThe additive manufacturing technologies that are being used most for the manufacture of products or tools are known as dust bed technologies, these technologies are characterized in that they distribute the material in powder format in an XY plane for later, a high energy source intensity, selectively melt the material of the corresponding layer, with this process, layer after layer is able to manufacture the pieces. Powder bed technologies have multiple advantages, which is why they have been strengthened as the most used for the manufacture of products. Among the most relevant in the market are the technologies SLM (metal), EBM (metal) and SLS (plastic). It has been shown that the surface finish obtained with additive manufacturing technologies is very rough, both in plastic and metal and this greatly limits industrial applications, being necessary to develop finishing processes adjusted to additive manufacturing. This project is the improvement of the surface quality of additive manufacturing parts in order to improve their mechanical performance, these processes will be developed industrially for metal fabricated parts manufactured in EBM and polymer technologies in SLS technology. In this way, it is intended to obtain wide spectrum surface improvement pathways that solve said limitation and further enhance the industrial use of additive manufacturing. OBJECTIVESThe SKIN project aims to develop postprocesses to improve the surface of parts manufactured using additive manufacturing technologies, both in plastic and metal, by improving process parameters from the same technology, design of chemical and mechanical processes by finishing with a characterization of the results obtained to be implemented in an optimized product design methodology. To achieve the general objective of the project, it will be necessary to achieve the following specific objectives: -Improvement of the EBM (metal) and SLS (plastic) process parameters that influence the surface quality of the parts (contour parameters and internal fusion ). -Improvement of surface quality through mechanical, chemical, electrochemical postprocesses or a combination of them. -Characterization of quality improvement through fatigue tests. -Development of a brazing welding process as well as establishing its geometric and surface conditions. -Application of the previous results in case studies that are optimized. -Validation of cases through product tests.
