The Smart3D laser-scanning package from PERCEPTRON is described as a "productivity breakthrough" for reverse engineering and modeling, with fully integrated automatic rotary table and intuitive programming software. A simple, teach-and-repeat process allows scanning of repetitive parts using the ‘Auto Rescan’ feature. The accuracy of the acquired dataset is significantly enhanced over equivalent data acquired using manually operated scanning systems.
Smart3D automatically provides 3D polygonized models for reverse engineering, 3D printing, or graphical web content. The Smart3D system also can be used to verify production parts against nominal part geometry data.
Smart3D incorporates Perceptron’s patented Helix "smart" scanning sensor technology, which is used widely in the global automotive industry for in-process laser scanning of car bodies for dimensional stability and gap and flush measurement. Helix incorporates MEMS technology and offers the world’s first programmable laser scanner, whereby the laser line quantity, density and scanning volume are fully user programmable, negating the necessity to physically move the laser scanner over the part.
All scanning motion is contained within the Helix smart scanning sensor itself, dramatically improving quality of scanned data while maintaining a volumetric accuracy down to 50 microns. The Helix configurable line density allows for scan line intervals programmable down to 0.1mm. Combining the features of programmable scanning volume, and line number and density for specific regions of interest on highly detailed complex parts allows for true scanning optimization.
The use of a coherent laser light source in the Helix provides a larger dynamic range allowing scanning of multiple colors and finishes. The dynamic range has been extended further by the incorporation of adjustable laser power control and dynamic auto laser intensity.
The Smart3D system is supplied with a fully integrated automatic rotary table that allows for 360-degree scanning of parts without the need for targets or best fit alignment. The overall scanning volume is 200x225x225 mm, which is compatible with the volume of most 3D printers.
From arrival at a scanning location, the portable Smart3D system can be fully operational in less than 15 minutes. The complete Smart3D system is easily transported in purpose-designed rugged equipment cases providing a truly portable solution. Smart3D can be used with a tripod for maximum portability or can be fixture mounted for the more demanding environment.
The scanned dataset is streamed real-time into the accompanying Scanworks® Studio data collection software with automatic full 3D STL model creation. The software comes with a complete package of tools to refine and enhance the completed scan project; the generated STL model can also be used with all major third-party point cloud and 3D printing software.
