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.
But now take care of our environment and yourself, it is Epoxy, and dangerous for our environment, especially our water environment, so do not rinse your "water-based resin" print under the tap, it is toxic to our aquatic environment and there is micro plastic out in with the water. Rinse it in bucket of water and recycle this rinse water several times, then run it to the recycling site, which then takes care of it. Then we protect our environment.
