MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
So I recently printed a Mk. IV Halo helmet and that was 60 hours of print time given the scale and all of the pieces. I used an Ultimaker Replicator 2+. I would think that the print time would be the same, if not more. So take that as you will.
