Q: What are the advantages of 3D scanning versus CMM?

Speed, efficiency, accuracy, versatility and totality. Most easily handled objects can be scanned in an hour or less. Millions of points are captured with each shot or pass of the sensor making it easy to collect points all over the object with similar accuracy to that of a CMM. Compared to recording hundreds of points in a matter of hours with a CMM. Laser and light 3D scanners are not confined to a stage size, they are portable and can move around any sized object.
