4 Key Benefits of Using 3D Scanning for Dimensional Measurement and Reverse Engineering

May 4, 2018 | < 1 min read

The manufacturing industry is experiencing a surge in productivity which is leading to an ever increasing need to verify that the parts being produced meet the specified requirements. When timelines are critical and tolerances are growing ever tighter, it is imperative that the quality process involved in reinforcing the part’s requirements consistently adds value to manufacturing. The parts manufactured today have increasingly demanding measurements, and are outgrowing the traditional systems used to measure or reverse engineer them. 3D scanning is a cost-effective solution that brings accuracy and versatility to the evolving landscape of the metrology industry.

4 Key Benefits of 3D Scanning

  1. Coverage – In just a matter of minutes, 3D scanners can collect and measure millions of data points on the surface of an object. This efficiency was not possible before the technology was introduced, which is why it has seen such explosive growth in such a short period of time.
  2. Speed – Manual measurement takes a long time and is limited by the amount of data that can be practically collected. 3D scanning offers a fast way to automatically collect millions of data points at the speed of light. This reduces the time it would take to traditionally produce CAD models of prototypes or 2D drawings for reverse engineering. By increasing the rate of surface data acquisition, 3D scanning brings unparalleled speed to the inspection process.
  3. Accuracy – As the technology has improved, the accuracy of 3D scanning has increased over time. Currently, modern scanners provide a high degree of accuracy which is only expected to improve as the ability to collect more and better data points increases.
  4. Cost – The price of 3D scanning is competitive with other dimensional measurement technologies, especially when you factor in the time savings. Many 3D scanners are also easier to use, which helps to maintain lower training costs.

The type of 3D scanning used will be dependent on the part’s surface characteristics such as reflectivity, transparency, and roughness. In some cases, structured light scanning is not an appropriate method because diffraction and reflection can affect the measurements. The best way to decide which type of scanning makes the most sense for your application is to work with a qualified 3D scanning provider that has extensive experience with multiple scanning technologies.
