Z Corp. (Burlington, Mass.) has developed the ZScanner 600, a portable 3-D laser scanner that provides high-resolution 3-D data capture for product design and reverse engineering. It features resolution down to 0.1 mm and XY accuracy up to 80 microns. The ZScanner captures data in one continuous scan rather than in numerous shots from fixed positions, eliminating post-processing time to integrate static shots into a cohesive scan. ZScan Lite software, included with the scanner, automatically produces an .stl file for import into a 3-D CAD software package or for output to a 3-D printer.  To begin a scan, the user "paints" the object with a projected laser crosshair. The surface is recorded by the ZScanner 600's binocular cameras. ZScan software generates a polygon mesh of the surface in real time. Because the scanner is self-orienting and part-referenced, it lets the user move the target object during scanning.
