Abstract
A method and device for scanning, in connection with the production of a three-dimensional body, an outer contour of a rotating model with a scanning device operating at a scanning angle relative to the rotational axis of the model includes rotatably supporting the model such that the contour to be scanned on the model has a preparation line exposed to the angled scanning device; applying the scanning device towards a surface situated on the model below the preparation line; scanning the contour with the scanning device while simultaneously rotating the model and vertically moving at least one of the scanning device and the model with respect to each other during the contour scanning.

A method for scanning, in connection with the production of a three-dimensional body, an outer contour of a rotating model with a scanning device operating at a scanning angle relative to the rotational axis of the model, said method comprising the steps of:
- rotatably supporting the model such that the contour to be scanned on the model has a preparation line exposed to the angled scanning device;
- applying the scanning device towards a surface situated on the model below the preparation line;
- scanning said contour with the scanning device while simultaneously rotating said model and vertically moving at least one of the scanning device and the model with respect to each other during said contour scanning.
A scanning device used in the production of a three dimensional body for scanning an outer contour of a rotating model comprising a scanning member operating at a scanning angle relative to the rotation axis of the model, means for adjusting the scanning member with respect to a surface of the model situated below the preparation line, means for activating rotation of the model, means for activating the scanning member for contour scanning, and means for effecting simultaneous vertical displacement movement between the scanning member and the model during the scanning.
