3D printing has become a more accessible medium for artists, with affordable desktop printers and online services available. However, the quality of 3D prints can lack detail and definition, making post-print finishing techniques, such as painting, a desirable option. Golden Artist Colors has explored the use of their paints on various 3D printing materials, including PLA, PETG, PA12, ABS, and TPU. Their tests have shown that acrylic and oil paints can be used on these materials, with some surfaces requiring primers for good adhesion (Source ID: 2, 3). Additionally, varnishing or top-coating 3D prints can help protect them from UV light, heat, and moisture (Source ID: 5). Golden Artist Colors' products, such as their acrylics and varnishes, can be used to enhance and preserve 3D printed artwork.
