Fast Curing Standard 3D Printer ResinSUNLU standard 3D resin will fast cure when it absorbs 395-405nm UV light from a resin printer(or resin curing machine), suitable for most 2K/4K/6K/8K resin 3D printers(LCD/DLP/SLA). Low Shrinkage and High PrecisionDuring the resin R & D, SUNLU engineers focus on how to reduce resin volume shrinkage during curing to ensure high precision and good stability.
