Wenzel ScanTec has integrated the blue laser scanning sensor called the Blu-Scan into an industrial 3-D portable computer numeric control (CNC) laser scanner known as Mobile Scan3D for executing mobile scanning functions.
The laser scanning machine is deployed in reverse engineering and part surveillance evaluation. Since the device enables complete CNC automatic scanning, the precision of the desired information set is improved throughout the identical data achieved by a mobile arm, and it automatically generates designed and systematic data, lowering the next data cleanup process and processing time.
According to the company, this novel Blu-Scan sensor exhibits 50µm laser thickness than the earlier red laser sensor versions with higher resolution and more tolerance to surface matters. The Blu-Scan sensor is robust, supplies constant thickness of the laser line across the calibration zone and produces lower distortions due to its short-range wavelength, enhances focus and produces a fine projection line. Thus all these functionalities lead to extended data collection rates, resolution data and highly precise processed images.

The MobileScan3D is deployed for various purposes and an additional rotary table can be utilized to rotate the part and execute a full scan pass, facilitating all the scans in the identical coordinate system. The entire system is numerically computer controlled and the results are highly recurrent and are autonomous. Various sensors can be exchanged and can be activated rapidly without re-evaluating the system.
The rotary table supplies CNC motion in three axes and improves fast part scanning of the system. The scanning path can be tracked by the user and the CNC rotary table functions through angular increment, lowering the scanning period for a wide sequence of parts. The mobility and the speedy configuration permits easy scanning on location eliminating complex, time consuming effort exerted by the prevailing mobile arm scanning systems.
The time required to reach the scanning area for complete functionality is less than 10 min. The entire system is carried in two or three cases, upon the inclusion of the rotary table. All cases can be joined as a single unit for facilitating transportation and can be coupled to a portable trolley for further convenience. The joining wires are colored and the sensor configuration and installation can be done rapidly. The devise can be employed with a tripod for enhancing mobility or can be fixed on a support table.
The scanned ordered dataset is processed live into the data validation software. A 3-D computer-aided design (CAD) pattern can be created for output in IGES, STL, ASCII or STEP file formats.
The MobileScan3D is available with the company’s PointMaster V5 basic scanning module. Optional working modules can be included for reverse engineering or calibration of scan data with the nominal CAD information.
