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 have seen ultimakers "eject" parts at the 3d printing event in eindhoven.
Ejecting is pushing the printed object out by hitting it with the nozzle. At first glance this seems like a bad idea for the nozzle but it works for the ulitmaker people.
