Makerbot just unveiled a prototype of a new 3D scanner at SXSW, designed for the casual 3D printer users out there.  It’s fast, but what’s really key is that it produces water-tight models (no gaps in the surfaces) that are ready to scale and send to your printer.  At this point, details are sparse…stay tuned to this blog for updates or sign up for email updates directly from the source at Makerbot.
