VIDEO: Handheld Scanners Bring Metrology to the Shop Floor

Creaform showcases non-contact, lightweight and portable metrology scanning device.

Metrology has historically been about touching a part with gantry or bridge-type coordinate measuring machines. However, in the new, non-contact world there are other, easier ways to do it.

The Handyscan 3D from Creaform, for instance, is one example of a portable, non-contact scanner.

“Basically, with our Handyscan 3D we can capture both the reflection of the laser line with its two cameras, but the target is also laid out to scan and dynamically track the part,” said Francois Pare, account manager at Creaform.

Point targets laid out across a part can be placed randomly to assist the Handyscan in creating a more accurate part.

The scanner collects up to half a million points per second along the laser line. Collected data can be processed through CAM software apps to generate mesh files in standard formats for sharing and quality inspection.

The scanner is only limited by transparent materials, such as some plastics and glass. Powders or paints of any color or shade can be used to correct this issue.

“As the scanner is handheld, we can scan the part easily, as if we were spray painting the part,” Pare continued. “At the same time, the part can move. We don’t need a rigid setup to do this. What we want for this device is to bring metrology to the shop floor.”

As an optical device, the Handyscan 3D is not disturbed by vibration.

“Basic training takes only a couple of hours. With the Handyscan 3D, anyone can start scanning parts anywhere.”
