When full of balls and glaze this Royal Doulton ball mix weighs about 80 lbs. If efforts to pour it out don't cause a hernia the slurry ends up spilling everywhere as the balls come out with it! Trying to stop the balls with my hand ends up spilling even more. The answer was to 3D print a spout and a ball retainer. The bar and screw that normally hold the lid on work well to hold this in place. For multiple batches of the same glaze, it can now be poured right from the rack, no need to carry it to our sink. And not a drop spills. In the upper right picture, I had to change the filament midway, from green to black. It was easy to draw this in Fusion 360. I first printed the ring and flange to be sure of a good fit into the rim. A rubber band stretched around the flange provides a very good seal with the jar.
Standard 3D printing technology (not printing with clay itself) is very useful to potters and ceramic industry in making objects that assist and enable production.
A method of grinding particles in ceramic powders and slurries. A porcelain, metal or rubber vessel filled with pebbles tumbles and particles are ground between colliding pebbles.
