3D Laser Scanning
3D Laser Scanning is used primarily where very complex parts are required to be reproduced. Items such as moulds, turbine blades with complex aerofoils and geometries are typical examples.
Other items such as the impeller shown in the picture which have variable angled vanes are also typical of the type of items ideally suited to 3D Laser Scanning. The scanning process collects 18,000 points per sq. inch which would be impossible to collect manually.
The scanning is so accurate that it will reproduce every surface imperfection in extreme detail. Since these fine imperfections are not desirable in the finished product, additional software is used to recreate the final surface required. With this type of equipment, the possibilities are limitless!
