High Precision and Low Shrinkage】Designed for reducing volume shrinkage during the photocuring process, ELEGOO 3d printer resin 8k has significantly lower volumetric shrinkage and significantly higher accuracy than others, which brings smooth surface with great resolution for print model. Print times vary a lot depending on what printer you have, especially if you have a monochrome screen which had normal exposure times of around 2-3 seconds. To dispose of water washable resin and the contaminated water, take the container and cure it with a UV light or by leaving it in the sun.
