Evanescent Matting Spray for 3D Scanning

No cleaning is required.

SPRAY | SCAN | DONE

Even with state-of-the-art scanners, it is necessary to apply the matting spray in several application cases:

a) Transparent parts

Since we are dealing with optical technologies, the light must be reflected from the surface into the scanner's sensor. In the case of a transparent surface, however, the light will pass through the surface instead of being reflected by it. As a result, the scanner is unable to capture the surface structure.

b) Reflective parts

In case of reflective parts, such as a mirror, the light beams will be reflected in a focused way instead of diffused. This means that the chance of a beam hitting the scanner reflector is greatly reduced and the scanner will only capture a fraction of the reflected light beams.

c) Deep cavities

When the object to be scanned has deep cavities, the scanner receives a reflection from the cavity walls at the bottom. This causes disturbances in the light pattern that manifest themselves in the scan as "artifacts" or incorrect data.

d) High quality and precision

When quality and accuracy are important, you could apply the spray to remove color differences, reflection differences, texture, etc. as much as possible.

Using the spray creates a matt white coating that reduces reflections and other inhomogeneities and thus provides a perfect scanning condition.

In general, matting sprays used in 3D metrology for anti-reflective coating can be classified into the following two product groups:

Permanent sprays

• the surface remains white after scanning
• required cleaning or disposal of the scanned object

Vanishing sprays

• the coating evaporates automatically
• no cleanup required after scanning
• no contamination from pigments of laboratories, sensors, environments, scanners and users

AESUB blue - strengths

AESUB blue is an evanescent scanning spray, developed by scanning experts. The spray evaporates within a few hours, which means there is no need to clean up after scanning. Unlike traditional sprays, AESUB blue does not contain pigments and therefore avoids pigment contamination of sensitive areas, such as laboratories and production sites, equipment and users. AESUB blue can therefore be applied directly, at the scanning point, without any expensive transportation to avoid the aforementioned pigment contamination in sensitive areas. Overall, AESUB blue significantly increases efficiency and productivity in digitization processes.

The features of AESUB blue are:

• evanescence
• time and cost saving: no subsequent cleaning is necessary
• layer thickness of ~8-15 μm
• Pigment-free: The spray powder does not damage the sensitive scanning technical equipment
• consistent, homogeneous coating and dry to the touch
• The reference points (markers) stick to the lining
• Optimized material compatibility
• excellent scannability
