I'm new to 3D printing but have been using this resin with an Anycubic Photon. Prints have been exceptional using the mfg resin and I especially like using the Grey for D&D minis as it shows the incredible detail obtainable from the printer/resin combo. The price is very reasonable for a product of consistent quality. I filter and store unused resin from printing back in the bottle and haven't had any issues despite exposure of a day or two outside the container. Grey is my goto but I've tried a couple of other colors with similar results. Anycubic resins will be my primary print media. I wear gloves and a mask while working with the product but haven't had any reaction to either the smell or physical contact when it has occurred.
