Assembler

Overview
A machine used to craft advanced items automatically.

Website Description
"A constructor, but more! Capable of creating more complex parts out of more and more complex parts! A lot of complexity in such a deceptively small building!" -FISCIT Introduction.

Used to Craft
1. Rotor + Stator = Motor

Speculation
The Assembler, as described, is likely a more advanced version of the Constructor. It's capable of creating more complex products from more complex input materials, perhaps objects such as advanced circuits or computers. Due to this higher level of complexity, the machine will likely cost more to craft.
