Accuracy, with no doubt, is the essential requirement when you are going to purchase a 3d scanner. Each EinScan 3d scanner was factory-tested and achieved, at least, the listed accuracy from the technical specification.

0.04 mm (Fixed)

0.05~0.1mm (under the projected view in hand held mode)


EinScan provides two ways to verify and assure accuracy.

1.Factory tested accuracy according to VDI/VDE 2634 standards.

The scanner accuracy from the technical specification are tested,  which complies with VDI/VDE 2634 standards.

The tested model:

EinScan Pro 2X Plus


Test method:

The reference object (a set of certificated ceramic ball bar) is scanned in suggested 7 different positions according to 2634 Part 3 standards, and measured sphere spacing error, which defines the length in between the centers of two spheres and compares it to the calibrated length, so as the define the deviation.

(Proposed set-up for the error of length)

(Ceramic ball bar)

Artifact information:
Calibrated nominal dimensions:
Sphere spacing: 100.2623mm
Diameter left sphere: 38.0806mm
Diameter right sphere: 38.0833mm

Ball bar was calibrated by Shenzhen Academy of Metrology & Quality Inspection


Test result:

Sphere spacing errors of single measuring volume

2.Customer Calibration

Besides factory tested guarantee of accuracy, each EinScan is also coming with a calibration set, so users can do manually calibration themselves to ensure high accuracy. This customer calibration is not required daily often. Only when you have accuracy concerns, when the misalign or tracking lost is happened very often or after a long distance transportation.

EinScan is also able to scan by markers alignment to assure repeatability and better accuracy. Align by feature, texture are also available under different scan mode when accuracy comes secondary.

Work with EinScan, it will bring you a professional 3D scanning experience for high quality 3d modeling.
