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 think it's going to be higher than 1kg. Just the housing and LP/HP shafts weigh in at around 600 grams of PLA for me, and that doesn't include the probably 220g of support material (some of it was unnecessary in hindsight).
I suspect I'll be pushing around 2kg once all the fan/turbines/stators are printed.
