3D scan
Instead of creating a 3D model with the aid of a CAD program, a three-dimensional scan of the object can be made. The scanner scans the object completely and converts the scanning points obtained in the process into a data model suitable for 3D printing (polygonization). This optical recording method is suitable, in particular, for large and/or immovable objects such as buildings or for very complex items because of the extremely high surface accuracy.
