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.
For those looking for a fast 3D printing demo option, this is the best one I've found so far. When scaled down to 50% size with .35mm layers it only takes 10 minutes to print. Just within the attention span of elementary school age kids.
