Currently, there are many 3D scanners on the market with similar specifications. This makes it difficult to distinguish quality, especially when documents and advertisements often look the same. So how to recognize a high-quality 3D scanner?
Here are some simple tests that do not require special standard conditions, helping you to evaluate the actual capabilities of a 3D scanner and avoid parameters that are only theoretical on paper.
Shape deviation is the deviation from the ideal shape, such as a flat surface or a cylinder. This is an important criterion for evaluating the quality of a 3D scanner, because a high-quality scanner will record the shape closest to the actual value.
How to do it: Take a simple 3D cylindrical scan measurement to evaluate the scanner's raw data.
Result: If the outline of the cylinder is unclear, or you see the cylinder deformed into a mushroom shape, it indicates that the raw data may contain a lot of noise, reducing the accuracy of the 3D model.
The "mushroom" effect is easily seen when using a low-quality 3D scanner
Creaform's quality: As a pioneer in the field of handheld scanners, Creaform owns effective noise reduction technology, ensuring that the collected data is highly accurate without too much intervention from smoothing algorithms.
Evidence to support the claim: Cylindricality measured with Creaform’s MetraSCAN Black+™|Elite
Volumetric accuracy is the ability of a scanner to produce stable, consistent results over multiple measurements or between different users. A high-quality scanner will be able to repeat measurements with a small degree of error.
How to do it: Measure a part repeatedly with the same operator (repeatability) and with different operators (reproducibility). The results should be similar.
Result: If the difference between measurements is greater than an acceptable level (e.g., 30µm for a measurement 2m apart), this indicates that the scanner’s accuracy may not be as claimed.
The results are not as good as those obtained with a similarly priced 3D scanner (gray bar) compared to the volumetric accuracy measured by the Creaform HandySCAN Black+™|Elite (blue bar).
Creaform Quality: With over 20 years of experience, Creaform has continuously researched and developed to improve volumetric accuracy, ensuring the scanner is stable in real-world environments.
Thermal stability is how well a scanner maintains accuracy when operating under different temperature conditions. A high-quality scanner will be able to maintain accuracy over long periods of time and will not require frequent calibration.
How to do it: Use the scanner to measure a part, then measure again after 20 minutes, 1 hour, and 2 hours. Compare the results to see if there is a significant change.
Results: A high-quality scanner will maintain consistent results, while a poorer scanner may require frequent recalibration.

Creaform Quality: Since 2005, Creaform has been continuously developing solutions to control and optimize thermal stability, from mechanical design, optical structure to user calibration procedures.
By applying these simple tests, you will have a basis for evaluating and choosing a high-quality 3D scanner, ensuring that the specifications on paper truly reflect real-world performance.
