Easy lost PLA metal casting How to turn a 3d print into metal

Welcome to Robinson Foundry. In this video I will be using the lost PLA shell method to turn a 3d print into an awesome solid aluminum casting. I started by printing the model on my 3d printer and then coated it with joint compound. I then buried the shell in sand and sodium silicate and poured in the molten aluminum. This vaporized the PLA and leaving behind an awesome casting.
