Basics
- A metal casting technique where a plastic foam (such as polystyrene) object cut to resemble tje desired object 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 foam. 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
- Is simlilar to Lost PLA Casting
