The Form Studio 1 Resin Tank and the Resin Tank Pro are both designed for use with the Form Studio 1 printer, but they differ in their compatibility. The standard tank is optimized for printing with Alpha Resins, Flexible 80A Resin V2, and True Cast Resin, while the Pro tank is compatible with Tough 1500 Resin V2 and any material that requires Open Material Mode on Form Studio 1.
