This is a simple suggestion for a new type of machine. it combines materials of the same type into bigger blocks, thus reducing the amount of items a player has to store and also would reduce overall lag for player bases that do like storing tens of thousands of studs of every material out there.
Function:
1: Player has the usual selector interface for output shape
2: Secondary interface shows what material is already present in the machine.
3: Player inserts 2 pieces of material inside the machine. If material is the same it gets combined. If material is not the same both pieces are then ejected from the machine with no changes done to them except the shape which the machine is set to.
