The application of thin films as coating on several surfaces has been one of the major factors responsible for technological advances. Additive Manufacturing is used to define a set of technologies that have the building of 3D physic prototypes as a common characteristic. In this work we have studied the properties of Polyamide 12 samples obtained by rapid prototyping after coating with different metal transitions by sol-gel methodology. The sols were prepared with silicon, vanadium, titanium, or aluminum alkoxide. Thermal analysis revealed an increase in the decomposition temperature of the materials, which was attributed to the coating. Differences in the morphology of the films were detected by scanning electron microscopy, which depended on sol composition. The Raman spectra confirmed interaction between the coating and nylon substrate. The prepared materials exhibited new properties, such as higher thermal stability, while maintaining its initial characteristics, like low density, thereby promoting new potential applications.
