Kiln

The capacity to heat things up and cool them down. This will be important for 3D Robot early on. Since one of the ways to use metals is casting as well as ceramic sintering and much more. Making a kiln is a very easy task and is one that 3D Robot will have a easy time to do. There is also heating things up outside of a kiln and that is a separate process.

A kiln is ultimately made up of two major parts

Insulation

Heating

There are many ways to accomplish those two goals and to different degrees of success or set of conditions.
