The rules are as follows: SCP-914 cannot create, nor destroy matter. It is limited to whatever is put into the machine. The 1:1 setting will only create something similar. The Rough setting only generates the raw material for the object, while Coarse assembles only the basic components of the object. Fine improves the object, while Very Fine greatly improves the object. There is one experimental settings Ultra Fine: chance of creating an object so advanced, beyond human understanding.
