3D quality inspection benefits from optical and contact metrology. Laser scanning has come a long way over the last few years. Fueled by advances in information technology and the continuing march toward Industry 4.0, the devices have become more accurate and more affordable, capable of gathering millions of data points much more quickly and easily. The process has become steadily more intuitive, requiring minimal training, and the software has continued to enable more functionality and improve existing processes. Compared with contact metrology, laser scanning is undoubtedly faster, more portable and capable of gathering a much greater volume of data points in a single pass. But there are unique use cases for each kind of metrology. A 2016 article on Engineering.com referred to a poll that found users of laser scanning technology valued it for accuracy, speed and portability. Other advantages include colour capture/high definition resolution, cost and ease of use.
