I love 3D printers, but this is the third one I've seen this week in addition to MakerBot and Form 1. I'm really not understanding what the differentiator is after seeing the video except a slight change in price.
It is interesting to see competition to the MakerBot, since $2k is still a bit high, and if the PandaBot's "calibration-free" design works as well as they claim, the ease-of-use factor is still a big thing to exploit.
If it has even moderately good print quality, a commercial, fully-assembled FDM printer for under $1000 is an interesting prospect.
The basic thought was to get it to a point that we could provide it to designers and university students with little to no engineering experience and they could start printing their 3d models right away. Hence, the heavy emphasis on self-calibration and ease-of-use.
The price range just works because we also designed it from the start to be a manufactured product, so we get an economy of scale very quickly as more people pick it up.
You can see print quality examples on ponoko, Derek swung by our office to see it close up in action yesterday: http://blog.ponoko.com/2012/10/04/pandabot-3d-printer-launch...
I'm running product at Panda Robotics.
