Insufficient scan quality when scanning metal abutments with 3Shape lab scanners

Common issues with scan quality 

When scanning produced abutments as dies, in some cases the user can experience a low quality scan result - scan surface looks bumpy, lacks smoothness, or has holes:

Affected scanner models and software versions: any model, any version.

Possible cause: the scanned object is shiny/glossy and causes reflections during scanning.

Solution: in order to achieve a proper quality of scan result all reflective (metal, glossy plastic) parts should be sprayed with scan spray; if the object has translucent parts or very contrasting colors, scan spray may also be required. 

Important guidelines

1. The object must be thoroughly sprayed in order to cover all reflective parts. 
2. Please see below examples of insufficient spraying that may still lead to uneven scan surface:

3. The scan spray layer must be smooth and even, as the scan spray creates an additional layer on top of the object surface and will be scanned together with the object.
