Clear Castable UV resin is specially formulated to provide high definition moulds. It will leave almost no ash when burnt and create gas evenly as the temperature is increased, avoiding any pressure build up within the casting. It will capture all the details with a very dry surface to provide the ideal finish to your investment mould. Castable UV 3D resin for use with Laser Printers. Resin successfully tested with SLA 3D printers CTC, Formlabs 1 and 2 using their standard resin settings.
