It is a fantastic way to make detailed metal objects. It turns a liquid metal into a solid, precise part.This method is very old but also very modern. It has been used for thousands of years. Artisans used it to create statues and jewelry. Today, factories use it for high-tech parts. The basic idea is simple. You create a wax copy of the part you want.
