CAN CANNON PELLET CASTING MOLD

HAD SOME SMOOTH ON PMC-770 SHORE 70A TWO PART URETHANE RUBBER AT WORK AND DECIDED TO CREATE A BOLT TOGETHER MOLD FOR CASTING A FEW PELLETS FOR THE CAN CANNON. I MANAGED TO SQUEEK OUT 3 OF THEM. THEY ALL CAME OUT FLAWLESSLY. I HAD CONCERNS OVER THE INCLUDED RELEASE COMPOUND NOT WORKING AND OR DESTROYING THE PLA USED IN THE PRINT AND THANKFULLY IT WORKED PERFECTLY WITH NO ILL EFFECTS. IT MAY BE POSSIBLE TO CAST A VARIETY OF MATERIALS SO LONG AS THE RELEASE AGENT(S) WORK AND DO NOT DAMAGE THE MOLD.
