In line with our files on 3D printing processes, we will be starting today with a new series dedicated to the different techniques of 3D digitization. While the origin of the first 3D scanners dates back to the 1960s, this first portion will be focused on one of the simplest scanning technologies: laser triangulation.
The birth of 3D scanners goes back to the work of the National Research Council Canada, one of the first laboratories that developed a 3D digitization technique based on laser triangulation in 1978.
By definition, a 3D scanner is used to obtain a “digital image” of a physical object. To acquire this digital replica, there are different methods to record the object, which is then analyzed and reprocessed on a computer in order to determine its general shape.

NewsHow 3D Printing Will Change Manufacturing3D printing is a special type of digital fabrication called additive manufacturing. The difference between additive manufacturing and traditional techniques is that objects are created layer-by-layer, so there is minimal loss of material. This creates a potential for a more&helli
