Abstract
Despite the great potential of 3D printing technologies coupled with nanotechnologies, just few studies are present in the scientific literature. Application of nanocomposites materials for 3D printing in the field of cultural heritage restoration, is a promising approach to obtain novel and functionalized materials for the artworks element to be recreated. In this context, the present work aims to study innovative nanocomposites materials suitable for the considered application. A commercial PLA filament was additivated with SiC, SiO2 and TiO2 nanoparticles, synthetized by CO2 laser pyrolysis. Nanocomposite filaments were produced by a co-rotating twin-screw extruder and specimens were produced by 3D printing and analysed against their mechanical and hydrophobic properties by means of tensile tests and water absorption and contact angle measurements, respectively.
