In 2019, AMEXCI conducted a pre-study about polymer surface treatments aiming at providing an overview of technology trends, maturity of manufacturers and technologies, material capabilities as well as main challenges. Following the know-how put together in the pre-study, in 2020, an extensive study on different surface finishing technologies, i.e., blasting, tumbling, chemical dipping, and vapor smoothing, was performed to evaluate different suppliers/technologies as well as the effect on various commodity polymer benchmark samples, e.g., PA12 (MJF and SLS printed), Onyx, ABS.
