Metrology vs. industrial 3D scanner – what are the differences?

Although both types of devices are used to digitize objects, their purpose and capabilities differ significantly. Understanding these differences is important when it comes to choosing the perfect solution for your needs.

• 3D metrology scanners: are the absolute top in terms of precision. Created for tasks where there is no room for error, they offer micrometer-level accuracy (down to 0.02 mm). They are indispensable in quality control and wherever certified measurement compliance is required, such as according to VDI/VDE 2634 standards. Models such as the FreeScan UE Pro guarantee consistent and repeatable results, desirable in the aerospace, automotive or armaments industries.
• Industrial 3D scanners: they feature versatility and robustness, making them ideal for dynamic manufacturing environments. While they still offer high accuracy, their main advantage is the flexibility of their applications – from reverse engineering and rapid prototyping to maintenance. You’ll find handheld, desktop and even hybrid models that combine different technologies to meet any challenge.

Applications of 3D scanners in industry

Industrial 3D scanners streamline work in many sectors, such as automotive, aerospace, foundry, heavy industry, railroads and R&D departments. The main application areas are:

• Quality control: quickly comparing manufactured parts with a CAD reference model to detect defects and deviations,
• Reverse engineering: reproducing technical documentation for parts that don’t have it, or creating CAD models for modifications and upgrades,
• Process optimization: analyzing the wear and tear of molds, tools or entire machines to plan maintenance and upkeep,
• Rapid prototyping: verifying the geometry and fit of prototypes before launching mass production.

Applications of 3D scanners in metrology

3D metrology scanners are essential where certified precision and full measurement traceability are required. Their applications include:

• advanced quality control: creating detailed measurement reports and color deviation maps that clearly indicate quality problems,
• precision reverse engineering: creating accurate CAD models with a full history of operations, ready for further editing and CAM processing,
• Research and development (R&D): analyzing deformation under load, studying the effect of temperature on object geometry, or verifying the results of numerical simulations.

Metrology or industrial 3D scanner – which one to choose?

Choosing the right device may seem complicated, but just focus on a few important aspects.

1. Determine your goal. Is certified accuracy for quality control or speed and mobility for field work most important to you?
2. Pay attention to the technology. Laser scanners (e.g., in the FreeScan series) are great for glossy and dark surfaces, while structured light (e.g., in 3D professional scanners) offers high resolution and color scanning.
3. Match the device to the object. Are you scanning small, intricate details, or large dimensions like the body of a car? The choice between desktop and handheld depends on this, as well as the need to use the photogrammetry function, which reduces errors with large objects. It’s worth considering whether a hobby 3D scanner will simply suffice for a given object.
4. Don’t forget about software and support. Good software is half the battle. Make sure it is intuitive and offers the features you need. At CadXpert, we provide not only the hardware, but also professional training on how to use it so you can get the most out of your new device.
