Exploring the World of 3D Scanners and Scanning Technologies

In this blog, we delve into the various types of 3D scanners and scanning technologies, including a detailed look at industrial/CT scanning, and discuss why partnering with CADmore is a superior choice compared to purchasing your own scanner.

3D scanning technology has revolutionized various industries by providing precise and efficient methods to capture detailed representations of objects, environments, and even entire landscapes. With a range of scanning technologies available, choosing the right type can be crucial depending on the application. In this blog, we delve into the various types of 3D scanners and scanning technologies, including a detailed look at industrial/CT scanning, and discuss why partnering with CADmore is a superior choice compared to purchasing your own scanner.

Short Range 3D Scanners

Short-range 3D scanners are ideal for capturing small to medium-sized objects with high precision. These scanners typically use laser triangulation or structured light technology.

Laser-Based 3D Scanners

Laser-based 3D scanners employ a process called trigonometric triangulation to capture the 3D shape of objects. They project a laser line or multiple lines onto the object and measure the reflection with sensors positioned at a known distance from the laser source. These scanners are highly accurate and versatile, coming in handheld, arm-based, and CMM-based designs.


  • High accuracy and resolution
  • Effective on challenging surfaces (shiny or dark finishes)
  • Less sensitive to ambient light conditions
  • Portable and user-friendly

Structured Light 3D Scanners

Structured light scanners project a pattern of light onto the object and use sensors to capture the deformation of the pattern, which is then used to calculate the object's 3D shape. These scanners are also highly accurate and can be tripod-mounted or handheld.


  • Rapid data capture
  • High precision and resolution
  • Suitable for a variety of applications, from small objects to large areas

Medium and Long Range 3D Scannersartec-ray-ii-tripod

For larger objects such as buildings, vehicles, and industrial equipment, medium and long-range 3D scanners are essential. These scanners often use laser pulse-based (time-of-flight) or phase-shift technologies.

Laser Pulse-Based 3D Scanners

Laser pulse-based scanners calculate the distance to an object by measuring the time it takes for a laser pulse to travel to the object and back. This method is highly effective for scanning large areas quickly.


  • Capable of scanning large distances (up to 1000 meters)
  • Fast scanning times
  • Suitable for large-scale projects

Laser Phase-Shift 3D Scanners

These scanners modulate the power of the laser beam and compare the phase of the emitted and reflected light to calculate distances. While generally more accurate than pulse-based systems, they are best suited for medium-range applications.


  • High accuracy and resolution
  • Ideal for medium-sized objects
  • Efficient and quiet operation

Industrial/CT Scanning3D-CT-Scanner-Photo

Industrial computed tomography (CT) scanning is a powerful technology that uses X-rays to create detailed 3D models of objects, capturing both internal and external features. This technology is invaluable for applications requiring precise internal inspection, such as quality control, reverse engineering, and materials analysis.


  • Comprehensive internal and external scanning
  • High accuracy and resolution
  • Non-destructive testing
  • Suitable for complex and detailed inspections


Choosing the right 3D scanner depends on the specific requirements of your project, whether it involves scanning small objects with intricate details or large structures with high accuracy. By understanding the capabilities and benefits of each type of scanner, you can make an informed decision and leverage the power of 3D scanning to enhance your workflow.
