The resin or synthetic resin is a liquid plastic that cures under UV light. Stereolithography 3D printers use these materials. A solid model can be created by curing photosensitive resin with light or a laser. The 3D printer exposes the liquid resin at the desired locations, curing it. As a result of this technique, components with high surface quality and detail can be produced.
One of the advantages of resin is that it has several material properties. This way, you can choose the resin that best fits your needs.
