3D optical scanning is in principle the transfer of a physical object into computer data by means of a 3D scanner. In comparison with contact measuring systems the optical scanner picks up the whole surface at a time. After scanning it creates a computer model of the scanned object and this enables its subsequent export to various data formats. Further function of the optical scanner is comparison of the physical object with the CAD theoretical model and evaluation of shape and position deviations.
The system of 3D scanning in Evektor is supplemented by technology of 3D printing and technology of vacuum casting which are known as Rapid Prototyping. These technologies are used for fast production of fully functional parts with properties close to the real product and they can even replace it.
The technology of Rapid Prototyping along with 3D scanning can be successfully applied at reconstruction of parts, e.g. by means of Reverse Engineering method.
