how does a blue light 3d scanner work?

A blue light 3D scanner works by means of structured light technology to capture the geometry of objects with high precision. It projects a series of blue light patterns onto a surface, and then a camera captures the deformation of these patterns. From these deformations, it calculates the shape and dimensions of the object. It is very effective in the scanning of small to medium-sized objects, accuracy level might be within 0.1 mm. For instance, the blue light 3D scanner scans up to 0.03 mm and thus happens to be very ideal for high precision applications, including automotive design and the preservation of cultural heritage.

The light source used is normally in the blue spectrum, since among the different colors, blue has a shorter wavelength, giving detailed and sharp images of the object being scanned. Indeed, studies have indicated that up to 30% higher accuracy can be achieved with blue light scanning technology compared to using other colors, such as red or green, especially in high-detail scanning applications. Companies like Revopoint have taken this technology to build scanners capable of capturing details both in bright and dim environments without loss of quality in scanning. One of the strong points of blue light 3D scanning compared with traditional contact methods is that it’s really faster. It is contactless, which really cuts down on how long it takes to get the data correctly. Objects can be scanned in as little as 30 seconds, while older methods like laser scanning or photogrammetry take several minutes to hours, depending on the object’s complexity. This speed and efficiency have made blue light 3D scanners popular among industries like medical device manufacturing, where precise models of complex parts are often needed quickly for prototyping.

Besides, blue light 3D scanners are highly valued for their versatility. The ability to work with a wide range of materials, from shiny metals to rough surfaces, without special treatment or coating, sets them apart. For instance, aerospace engineers would make use of this technology in the inspection of intricate components with tight tolerances, such as turbine blades, even when they are small, say about 5 cm in size, but with very detailed structures that require extremely high accuracy.

Until recently, structured light scanning was done on a smaller scale because of the high costs involved in the purchase of equipment. Advances in technology and manufacturing, however, have shrunk the price of blue light 3d scanner by up to 50% over the last decade, within reach of small businesses and independent engineers who need quality 3D data without breaking the bank. In fact, it has been reported by the industry of 3d scanning that the adoption of blue light scanners has grown 40% in the last five years due to huge improvements in affordability and functionality.

With blue light 3D scanning being an ever-improving technology, applications may start ranging from educational usages to mass production. Inasmuch as this is capable of scanning in seconds and giving perfect 3D models, this technique would certainly serve industries depending on precision and speed effectively.
