3D scanning for high-precision measurement

Scanning

3D Scanning for Ceramics 3D Printing

In 3D scanning, the surface of an object is optically analyzed with high precision in order to generate and measure data on its shape and surface properties. The collected data can then be used to construct digital 3D models, for reverse engineering or for quality control.

If a real model is to be 3D printed without CAD data, 3D scanning is an effective way to digitize the model.
In addition, 3D scanning can be used for quality control when traditional measurement tools reach their limits.
The shrinkage and possible warpage in the firing of a 3D printed part can also be determined by scanning the part before and after firing and comparing the CAD data.

Procedure

How does the scanning process work?

WZR currently uses a strip projection scanner consisting of a beamer, two cameras and a turntable.
The object to be examined is placed on the turntable. The beamer illuminates the object with strip patterns of different sizes. These patterns are captured by the cameras and read out by a corresponding software. In addition, the object is irradiated with color in order to register textures and coloration of the surface. After all stripe patterns have been projected, the turntable continues to rotate automatically and the scanning process for the next section of the object is started.
