- Abstract
Polyamide 12 (PA12) is currently one of the most used polymers in the additive manufacturing industry in its various technologies. In Selective Laser Sintering (SLS), the purity of the material allows obtaining good quality parts. However, it is not clear an appropriate reuse of the material due to degradation in its quality during the process. Hence, users prefer not to reuse it and it is arranged as waste. In this paper, a comparison of PA12 powders virgin and waste is reported, analyzing if there is any change in its morphological, chemical, and crystalline characteristics. Then, a micrographic analysis is performed using SEM-EDS, structural analysis of functional groups by FTIR, and crystalline through XRD (X-Ray Diffraction). As a result, it was obtained that the particle size for residue quality is larger than the virgin. On the other hand, FTIR and XRD analyses showed the presence of the same functional groups in virgin PA12 and residue and similar crystalline properties in both substances. It concludes with a recommendation for how to reuse the polymer considering strategies for increasing particle size.
