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.
I find that each printer, and each slicing program seems to have different requirements depending on the settings you select. One print I did (of a different design), the slicer said would take 1hr 15 minutes, but the printer reported 1 hr 25 minutes on completion. Something this small shouldn't take all that long, or use a lot of filament.
