Why and how are 3D printed parts coated?
Today, 3D printed components made in the most diverse materials are increasingly widespread, thanks to the possibilities offered by this fast, inexpensive, and waste-free production technology conceived for prototyping or manufacturing parts with complex geometries. However, even these parts are subject to wear, corrosion, and harsh environmental conditions that can compromise their aesthetic and functional characteristics. Therefore, they must be protected with a surface coating. In this article, we analyse why and how plastic and metal 3D components are coated.
