Green light has been found to be more accurate than the blue spectrum for three-dimensional (3D) scanning, according to German developer and manufacturer of 3D systems, Breuckmann. 

The company introduced blue light into its scanning systems in 2004, and was one of the first in the world to do so. Further research and development has led to the use of a green light system, which was introduced to the industry at the 2011 Euromold exhibition. 

Green light, according to Breuckmann, allows more accurate customization of the 3D data acquisition process to meet individual project requirements Breuckmann, which started producing 3D scanners a quarter of a century back, says 3D scanning systems have “become powerful and reliable partners in the tooling and mould making industry, beginning from the creation of the inaugural prototype all the way to the stage of mass production”. 

The contact-free scanning process generates highly precise digital data even of very fragile and easily deformable objects within a matter of a few seconds for further processing. 3D has also become an integral quality inspection tool which is used whenever small components or minute deviations have to be measured to the highest level of accuracy. Another advantage of 3D is that it measures the entire object, rather than individual points which tactile systems rely on.

3D scanning systems can be tailor-made to the needs of the customer. The exact performance spectrum of the system is determined by the customer by choosing from a variety of configuration options. Scanners are configured to suit individual project requirements, with module-based configuration providing both hardware and software flexibility. Low-noise CCD cameras using high-quality lenses at various resolution levels ensure accuracy and high data quality. Optical 3D systems are also able to measure high-gloss surfaces, according to Breuckmann. 

Its naviSCAN 3D enables RPS-alignment of already processed and high-glossy reference points. From the very first measurement acquisition, the scan data generated by the naviSCAN 3D can be compared online against the existing CAD data. Large components, such as doors, can also be scanned. Breuckmann’s stereoSCAN 3Dcan scan areas of up to one square meter per shot. With the help of the navigation target mounted on the back of the scanner, scans are stitched together seamlessly, and without any need of user interaction. The navigation target allows complete freedom for any movement and position of the scanner. During the scan sequence, the system monitors and corrects for any movement of the scanner or component. The electro-optics navigation system has been developed by Norwegian company Metronor.
