We have a small(emergency) and medium 3D printer, will there be a big 3D printer? Or is the replicator the big 3D printer, in terms of what it does I would say yes.

If that were the case, it would have to use minerals and electricity and not parts. It would nice to see some animation, like nanites inside the glass tube on top of the replicator that drain as the blueprint is being built.

If there is a large 3D printer coming, I would like to see that there is enough storage space for a stack of each part and a queue spot for each part. And a checkbox for not conveying parts to storage containers.
