The Royal Netherlands Navy is 3D scanning all their ships

Marinebedrijf Koninklijke Marine, is the organization responsible for maintaining the

vessels of the Royal Netherlands Navy, and recently partnered with Artec 3D to 3D scan the country’s entire naval fleet, according to Naval Technology. The project is a massive undertaking, but once complete, it will dramatically speed up ship maintenance and replacement part fabrication. As some parts don’t have manufacturing blueprints or 3D CAD files available, these scans will not only serve as a reference library, but will also allow the navy to print components for ships like submarines or minehunters on demand. The organization is using two types of handheld Artec scanners: the Artec Eva and the Spider 3D. The scanners work by projecting light in a grid pattern onto an object. It then calculates the distance from the scanner to multiple points on the object by looking at distortions in the projected pattern. These points are then used as coordinates to create a 3D model of the object.                                                                                                  https://www.theverge.com/2017/10/1/16387528/royal-netherlands-navy-dutch-3d-scan-ships-artec
