With continuous advances in optical inspection technology yielding 3D scanners that are today capable of stunning speed and accuracy, a growing number of companies are including this technology in their first article inspection (FAI) procedures.
What started as a project to investigate the accuracy and reproducibility of reverse engineering a product using computed tomography (CT) and additive manufacturing with 3D printing technology has helped to establish some guidelines and processes for the future of high-quality “3D copying.”
The American Society for Nondestructive Testing (ASNT), which facilitates the largest organized society for nondestructive testing professionals, currently lists fourteen viable NDT inspection methods that can be used today.
Many new industries are employing 3D scanning not only to create 3D models of parts or products for reverse engineering but also to explore the composition and rapid production of ready-to-use parts via 3D printing.
The most accurate CT scanning systems are built like a CMM with an X-ray probe.
