Longtime rapid prototyping professional Mike Durham has started a 3-D scanning service bureau called Absolute Geometries (Pflugerville, TX) in the Austin, TX area that specializes in computer-aided inspection for the injection molding, casting and RP industries, and reverse engineering services.

After extensive research, the company selected the Faro Laser Scanarm V3 scanning and touches probe hardware system, and Rapidform XOS and XOV software. Scanning services are offered at Absolute Geometries facilities or at the customer’s site.

Because of Durham’s experience in rapid prototyping, the company offers what they call "RP Equipment Optimization". Utilizing 3-D laser scanning and Rapidform Verifier software, Absolute Geometries scans the rapid prototype model and overlays the scan data with the original STL file. The result is a 3-D color interactive model showing the deviation between the model and the file. Every surface of the part is measured, not just selected points as with a CMM.

The process helps to determine not only where the model might be out of tolerance, but also the reason why. With simple measurements, it is difficult to determine the reason for the out-of-tolerance dimension. With this process it is easy to see if the problem is a localized issue such as curling, warp, or scanner calibration or a more general problem such as beam compensation, shrink, or Z offset.
