Accuracy is measured in distance - a bound on the maximum distance from any scanned point to the true surface. Manufacturer accuracy ratings should be taken with many grains of salt.

Makerbot is claiming +/- 2mm. In comparison, high-end laser scanners claim accuracy in the tens of microns, 50-100x better than MakerBot.

12 minutes is a slow capture time for small parts like that.

$1400 is cheaper than any good 3D scanner on the market, by far. The only competition is a Kinect, which costs much less but doesn't have enough detail for small parts yet.
