4. Case Studies for Better Scanning

Scanning Results for Objects That Are Difficult to Scan

These are some examples of scans of difficult materials. (The plated object was specially scanned for experimental purposes only. Avoid

highly reflective objects because of danger of eye injury.)

Choosing the Scanning Mode

This example involves using the two scanning modes to scan an object that has cavities and a complex shape. Plane scanning is suited to

objects like this.

Rotary Scan Plane Scan

* In these cases, applying a white surfacer (primer) or the like may yield good results.
