Resin modeling on SLA

3D printing is often used to create the first product. After that, a mold is removed from the product, and then production is done by casting. The subtlety is that the mold conveys all, even the smallest scratches, surface structure. The easiest way to get a high-quality glossy surface of printed 3D models is chemical polishing. The models in the photo show the result after and before chemical polishing.
