Lost PLA Casting

Basics

- A metal casting technique where a PLA (or other low tem thermoplastic) 3D Print is placed in greensand, then metal is poured through a spout leading to the buried 3D Print. The metal the melts and burnes out the plastic. This leaves a clean (hopefully) metal cast

- Is more easily repeatible than origional object to green sand empty cavity casting, but is still not a "permanent mold"

- Can introduce some more problems than origional object to green sand empty cavity casting due to the plastic not melting/burning completely, or this process causing the metal to cool to quickly
