Hexagon’s Manufacturing Intelligence division introduces two new handheld 3D scanners, the Atlascan Max and Marvelscan, that are suited for measuring parts in a wide range of inspection environments where metrology has not traditionally been used, including applications in automotive, rail, industrial equipment and general manufacturing, as well as heritage and restoration projects outside of manufacturing. The 3D scanners are suited for handheld and automated quality inspection applications, and for a wide range of reverse engineering needs.

“Today, manufacturing and engineering teams recognize the value of up-to-date 3D scans throughout the product lifecycle. This means almost anyone might need to perform a metrology-grade scan of a part regardless of their location,” said Pirmin Bitzi, General Manager for Portable Measuring Devices at Hexagon. “Our first handheld 3D scanners enable customers to digitalise parts without worrying about fixturing or environmental conditions, and Marvelscan’s cutting-edge, integrated photogrammetry system aligns to reference targets without the need for stickering. Wireless and ergonomic, these scanners provide a seamless, instant scanning experience, from the shop floor to the shipyard.”

Atlascan Max and Marvelscan users can adapt workflows on-the-fly using ergonomic, thumb-operated controls that streamline 3D scanning processes in confined spaces and rugged or outdoor environments. Eliminating the need to access a control PC during measurement, this multimode scanning enables different feature types and surface needs to be measured efficiently. For example, users can scan open surfaces with Standard mode, then quickly switch to Fine mode with the on-device controls for higher resolution on intricate features. The data collected under these different modes are automatically combined into a single, workable point cloud.

The devices also eliminate the need to fixture parts prior to measurement, which contributes to time savings and allows greater measurement flexibility. The scanners and parts can be moved freely during measurement, reducing the time it takes to capture complete part data without negatively affecting inspection results. For further productivity gains, the common and time-consuming task of measuring multiple holes and slots is made easier with a hole-flash capture mode that enables instant data capture of multiple holes and slots in the same shot.

The Marvelscan raises the bar for 3D scanning productivity higher with the built-in photogrammetry that offers targetless scanning functionality. This is suitable for scanning large parts and repetitive parts without the time-consuming task of place targets on the part itself. This photogrammetry function also enhances scanning accuracy for large, delicate parts.

The handheld technology has capabilities for completely wireless measurement with battery-powered autonomy-a first in the metrology-grade handheld scanner market-putting the measurement system fully in the hands of the user without being tied to a PC or power source. When combined with their large measurement standoff distance, this makes the devices ideal for integration within automated inspection processes mounted on industrial robots or cobots.
