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.

Your Slicer should estimate the print time, which will give you a 'ballpark' idea - Often times that estimate is low as they don't typically account for retraction speeds, etc.
