Resin or synthetic resin are UV-curing liquid plastics. These materials are used in stereolithography 3D printers. The photosensitive resin can be cured by laser or light and thus transformed into a solid model. The liquid resin is exposed at the desired locations with the 3D printer, curing the resin. This technique makes it possible to produce components with high surface quality and level of detail.
Resin has the advantage that it has several material properties. So you can use the right Resin for every need.
