There are numerous 3D scanners available. Some of these can scan a complex object very rapidly. Most use a laser. Google "3D scanner"I have another question, is there any kind of camera or a machine that read the 3D dimensions of a product and enter this dimensions automatic to the CNC Milling Machine???
A few people have built mechanical scanners using a mill and a touch probe to actually feed a probe in until it touches the object. The laser scanners are fast, this process is very slow.
