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.
How does 3D printer resin work? In contrast to the solid filament spools that FDM uses, a 3D printer resin is a liquid solution. This liquid is basically composed of a mixture of different monomers and oligomers – short chains made mostly of carbon atoms and a few functional groups
