Evaporating matting spray for 3D scanning

No cleaning required.

SPRAY | SCAN | DONE

Even with state-of-the-art scanners, matting spray needs to be applied in several application cases:

a) Transparent parts

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

b) Reflective parts

In the case of reflective parts, such as a mirror, light beams will be reflected in a focused rather than diffuse manner. This means that the chance of a beam hitting the scanner's reflector is significantly 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 which appear in the scan as "artifacts" or incorrect data.

d) High quality and precision

When quality and accuracy are important, you might apply the spray to remove as many color differences, reflection differences, textures, etc. as possible.

Using the spray creates an opaque 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-glare coating can be classified into the following two product groups:

Permanent sprays

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

Evaporating sprays

• the coating evaporates automatically
• no cleaning required after scanning
• no pigment contamination of laboratories, sensors, environments, scanners, and users

AESUB blue - strengths

AESUB blue is an evaporating scanning spray, developed by scanning experts. The spray evaporates within a few hours, meaning no cleaning is required after scanning. Unlike traditional sprays, AESUB blue contains no pigments and therefore avoids pigment contamination of sensitive areas, such as laboratories and production sites, equipment, and users. It is therefore possible to apply AESUB blue directly, at the point of scanning, without any costly transport to avoid the aforementioned pigment contamination in sensitive areas. Overall, AESUB blue significantly increases efficiency and productivity in digitalization processes.

The features of AESUB blue are:

• evanescence
• time and cost saving: no subsequent cleaning is required
• layer thickness of ~ 8-15 μm
• pigment-free: the spray dust does not damage sensitive technical scanning equipment
• consistent, homogeneous, and dry-to-the-touch coating
• reference points (markers) stick to the coating
• optimized material compatibility
• excellent scanability
