AESUB: Upgrading the Quality of Industrial 3D Scanning

For all those who value precision and attention to detail when it comes to 3D scanning, the use of a spray is essential. Spraying the object with a special spray before the scanning process ensures a clean and matte surface, which not only improves the scan quality, but also enables the scan for some products in the first place. The spray is absolutely necessary for transparent or reflective objects, as the light from the scanner reflects from the surface back to the scanner. But using a spray also offers added value for other objects and has a significant effect on the quality. Significant differences are particularly evident in the precision, as the spray supports the scanner in recognizing possible differences in color, reflection or texture and thereby reducing heterogeneities.

The growing range of such sprays includes the products offered by the German manufacturer, AESUB. The Dortmund company has specialized in the development of sprays for 3D scanning. In addition to traditional, pigment-containing sprays, the manufacturer also offers volatile solutions, which have already received multiple awards. In the meantime, AESUB has been able to build up a global, growing sales network with more than 50 partners who sell the products. To find out more about the company, its products and visions, we talked to AESUB’s founder, Friedrich Schlott.

3DN: Can you introduce yourself and your connection to additive manufacturing?

In addition to my professional start in development at BMW, I now have more than 20 years of experience in the field of optical measurement technology. Before I founded AESUB around three years ago, I had already managed a measurement services company for several years. Today I see that additive manufacturing and optical metrology have been moving towards each other, especially in recent years.

Many processes start with optical digitization and then use the result for additive manufacturing. On the other hand, the printed component is often 3D scanned to validate the printed geometry. We regularly print the scan data of various components and are always impressed by the results of the printed 3D component and the process itself.
