3D Scanning Automotive Body in White (BIW) with FreeScan Trak Pro2

April 26, 2024

This article elaborates on 3D scanning an automotive body in white (BIW) with SHINING 3D’s FreeScan Trak Pro2. It emphasizes the significance and advantages of this technology in automotive manufacturing.

What is Body in White?

Body in White” (BIW) refers to the stage in automotive manufacturing where a car’s sheet metal components are assembled but not yet painted or trimmed. It represents the structural shell of the vehicle before adding the final components. Body in white plays a fundamental and critical role in automobile manufacturing because it directly affects the vehicle’s quality, safety, and design.

Firstly, by performing accurate 3D scanning of the body in white, automakers can ensure the fit between the body in white and individual components and improve the assembly quality of the entire vehicle.

Moreover, by comparing 3D scanning data with design drawings, automotive designers can identify design defects in time for adjustment and optimization, thus improving the performance and quality of the vehicle.

In addition, the automotive manufacturing industry has been digitally transformed. The digital model of the car body created by 3D scanning technology can support subsequent digital production and process optimization, thus reducing production costs and increasing production efficiency. Meanwhile, product quality and brand competitiveness can also be improved.
