The primary advantage of non-contact 3D scanning is that it captures millions of data points in only a few minutes. And because the entire surface of your part gets inspected, it reduces the chances that errors will show up later during the assembly process.
But to be practical in today’s manufacturing environment, and also provide competitive advantage for your business, a 3D scanner must be able to measure any type of surface – shiny, complex, colored, textured or dark – while delivering both fast AND accurate measurements. And if these three simultaneous requirements can be delivered in an automated solution, you will have a competitive advantage that is difficult to beat.
Unfortunately, most 3D scanners excel in two of the three desired areas. For example, a scanner can be both accurate and fast, but only on surfaces that are not complex or reflective. Or a scanner might be accurate and also capable of handling difficult surfaces, but only after time-intensive setup routines or laborious adjustments to the data acquisition process.
And sadly there are a number of systems that fail to deliver on several of the necessary criteria: they are slow because they require alignment targets and/or powder coating of a reflective part, plus their narrow field of view leads to creep in global accuracy, which is also degraded by the powder coating.
Fortunately, the Metronic 20/20 Laser Scanner was designed from the ground up to meet all four performance requirements: fast, accurate measurement of any surface (including complex parts that are highly reflective) combined with a high level of automation. So it is true….you can have it all in 3D metrology, if you select the right system.
