3D printing, also known as additive manufacturing, is the construction of a three-dimensional object from a CAD model or digital 3D model. This technology is utilized in many industries such as aerospace and medical equipment. With ever more stringent quality standards and high-quality demands from customers, printed components are to be inspected to monitor production quality. This is because any deviation in the printed design can degrade the integrity of the final product.
To implement a fast and effective way to analyze and trace deviations in prints, blue laser scanners are used that enable the comparison between printed components with the computer-aided design. The objects are moved past the scanners with a traversing unit so that a 3D image is produced from the laser profiles. These images are then compared with the CAD data by an expert system. This way, inaccuracies are detected immediately, ensuring high-quality production.
