subject: The Use Of 3d Scanners In The Automotive Industry [print this page] The newest models of these scanners feature technology that was un-dreamed of just a few years ago. For example, the dark surface mode function of this instrument allows for the measurement of objects with reflectance as low as 2.5% without the use of special darkrooms or spraying of the object. The result is the industrys highest level of low reflectance performance.
Through the dark mode function, extremely low reflectance surfaces (i.e., dark objects) can be measured and analyzed without having to be sprayed. Inaccuracies in measurement caused by uneven thickness of the layer that has been sprayed are eliminated.
Youll find 3D scanner technology at work on a variety of tasks within the auto industry including designing aftermarket parts, manufacturing, simulation, quality control, inspection, prototyping and reverse engineering.
The top of the line scanners have editing software that lets technicians use a motorized platform to rotate the scanning object 360 degrees. The scanner reads data at intervals of 60 degrees and then creates a perfect digital replica. Its easy to see why 3D scanners are used in the auto industry: many parts in a vehicle can cause serious injury or death if they break or are incorrectly designed. Scanners solve this problem with their amazingly high level of accuracy.
Because of the technology in these scanners, manufacturers can replicate virtually any part from a uniquely designed screw all the way up to the entire vehicle itself. This function is particularly useful in various prototyping and reverse engineering tasks.
Perfection is critically important in the auto manufacturing field. Technicians must have clear and accurate geometrical knowledge of the part theyre working on. The versatility of 3D scanners allows them to see every nuance of a part from every possible angle. These scanners operate quickly and results are always uniform.
3D scanners are available in various sizes. Some are small and easy to hold, others are large, heavy duty models. The accuracy they provide is unparalleled in the measuring industry: 40 m and a 1.31 million-pixel sensor.
In summary, scanners give designers, engineers and manufacturers the ability to see and understand every angle, curve and corner of virtually any vehicle part. Without this technology, it would be a guessing game. Simple photography would produce far less than desirable results. Careful hand drawing would never do in an industry where accuracy is so critical. Much of the safety we enjoy in our vehicles can be attributed to 3D scanners.
