I'll concur partially on that.

My replicator clones are 220x150x150.
It's not really big enough.
The he3d k200 delta is 200x about 265.
And I have made one thing that needed to be cut into 4 to print on that (viking helmet).

The thing is, A large volume printer will still print small stuff as well as a smaller printer, but a smaller volume machine won't print the occasional large item.
