A Fabricator can be used as a Project Table, but much easier to use. Groups of adjacent fabricators can be used to make an autocrafting system. Also the Fabricator can suck items from an adjacent (next to) inventory such as a chest or another Fabricator. Additionally, when attached to an Item IO block on a tank, the Fabricator can pull from that tank. By placing a bucket in the Item IO and leaving it white, the Fabricator will pull the filled bucket from the tank, use it in the recipe, and place it back in the tank to be filled again.
