« After testing several systems in complex procedures, we decided on the HandySCAN 3D scanner based on our decision criteria. We are still confident that we made the right decision today.
TÜV AUSTRIA AUTOMOTIVE GMBH is an accredited technical service provider specializing in the testing, inspection and approval of vehicles and components, as well as electro-mobile and automated driving systems. The company advises its customers on all relevant fleet issues, with an emphasis on the economical and ecological use of new driving technologies. Since 2018, the company has been using a HandySCAN 3D scanner in its workshop for its services.
Why invest in a new measurement system?
Today, most companies have measurement systems, or use services to measure components or whole objects. In the past, TÜV AUSTRIA AUTOMOTIVE has already used portable devices to measure the contours of brake linings on a vehicle. However, it was necessary to attach these devices to the vehicle with several adapters. By digitizing the required contour with the measuring tip, a point cloud was created and the contour was displayed in a 2D file in the AutoCAD program. Since traditional measuring devices were custom-made products, they could only be used for very precise applications. As a result, the company’s measurement capabilities were very limited. In addition, it was usually necessary to manufacture replacement parts that were very difficult to obtain and at a significant cost.
The challenge was to find a low-cost 3D measurement system that would also help the company expand its advanced inspection services in the future. The purchase was also influenced by additional criteria such as a visible improvement in the quality and traceability of measurements, as well as a reduction in errors. In addition, the new system had to be easy to handle, reduce the effort required to perform measurements and improve efficiency and user satisfaction. These many requirements had to be understood within a new, modern and scalable measurement system.
The choice of HandySCAN 3D
After three years of evaluating numerous systems and after TÜV AUSTRIA AUTOMOTIVE provided an overview of the measurement technologies available on the market, the HandySCAN 3D, Creaform’s portable 3D scanner, was chosen.
The HandySCAN 3D met the basic requirements for its suitability for applications in the areas of quality control, competitive product analysis, temperature control, transfer from 3D scanning to CAD, finite element analysis and reverse engineering. Mobility, flexibility of use and ergonomics were also factors in the investment decision. Thanks to the laser technology of the HandySCAN 3D, it is possible to use it outdoors in sunlight, as well as to digitize glossy surfaces without using additional white powder. The preparation of the 3D data, the quality of the data and the support provided by Creaform (e.g. the replacement of the devices in case of failure) also facilitated the decision. The accuracy of the 3D scanner played a decisive role for our future services.
Areas of application
The HandySCAN 3D is used in conjunction with VXelements and Geomagic Design X software for the most diverse measurement tasks performed by TÜV AUSTRIA AUTOMOTIVE, mainly in the workshop. In addition to measuring the circumferential distance in the wheel arch at the end stop, the 3D scanner can also be used to measure rims, floors, cases, RDKS sensors, engine compartments and gaps when replacing components. In the future, the 3D scanner can also be used to assess hail damage to body parts.
After testing several systems in complex procedures, we decided on the HandySCAN 3D scanner based on our decision criteria. Even today, we are still certain that we made the right decision, » says Dipl.-Wirt Friedrich Fleischer. The purchase of the HandySCAN 3D has already paid for itself within a short period of time. Previously, two employees had to operate the measuring system, whereas only one is now required with the 3D scanner. The FMECA analysis has shown that the use of the 3D scanner has considerably reduced the risks. Data can be more easily traced and verified, which means that most of the costs associated with direct and indirect errors can be avoided in the future.
