wow, thanks for the extensive answer Aardvark!
I used to have a printrbot a few years back and everything broke down on that machine. (it was a good company but it was the early days of 3D printing and they didn't solve all the problems in time, they are now out of business)
In a youtube video I dug up after I posted the question it said pretty much the same thing.

Yes, a second printer is unavoidable I think!
I make naturalistic human figures. 3D printing allows me to preview the various details before sending a file to the foundry. For every real life statue I make, I usually print at least 5-6 scale models and partial prints of challenging areas
