Dimensional Measurement, Inc. (DMI) offers a variety of vision inspection and non contact inspection services, which are useful in measuring free-form parts and become necessary when measuring flexible or fragile parts. Depending upon the part submitted and the required data output, we can utilize the equipment that best suits your application – or combine our capabilities to produce the desired final result. These services include:
- 3D Laser Scanning
- Reverse Engineering Services

Faro Laser Scanner
3D Laser Scanning or Laser Digitizing utilizes a beam of laser light to capture the physical shape of the subject part, and produces a digital image, or point cloud. Laser digitizing is among the most versatile non contact inspection services because it is highly portable, suitable for a wide range of part sizes, and capable of obtaining a
large amount of data. Laser Scanning can also be used in tandem with DMI’s contact CMM measurement methods to create reverse engineering solutions that neither measurement method can provide on its own. DMI’s 3D laser scanning services can be performed either at our facility in Wixom, Michigan, or our metrologists can come to your
facility, which is exceptionally helpful for large or sensitive parts.
- Laser Scanning created Color Map
The 3D Laser scanning process can provide either 3D or 2D (cross section) results to compare scanned parts to their CAD models. A 3D comparison provides a color map of the CAD model displaying deviations between the 3D model and the physical part. A 2D comparison provides a whisker plot and deviations shown by both color and length of the whisker. Both provide a very complete picture of the
part’s condition.
