Aesub Transparent from Aesub is a new scan spray that temporarily mattes glossy surfaces with a transparent film. This enables optical scanners to capture not only the surface contours but also the color values of the measured object at the same time. As traditional scanning sprays produce a white coating, capturing color information was not possible when using previous spray variants.
Aesub Transparent does not contain any pigments and is also free from titanium dioxide, which is hazardous to health. The spray creates a layer thickness of approximately 8 to 15 µm. The coating evaporates after approximately four hours with no cleaning required, according to the company. Similar to the other sublimating Aesub scanning sprays, Aesub Transparent can be applied directly on spot of scanning.
One of Aesub Transparent’s applications is in 3D scanning when the color information of an object needs to be capture alongside the dimension and contour. Especially in reverse engineering of complex parts with extensive color information, Aesub Transparent significantly simplifies and accelerates the scanning process, the company says.
Reference points, such as the Aesub Dots, also adhere to the transparent layer from the spray and can be easily removed again after scanning.
