3D scanning is the process of digitally gathering an object’s surface data to determine its shape, enabling users to either replicate the part by reverse-engineering it, or inspect it through dimensional analysis.
To achieve this, operators use scanners that employ lasers, light, or sensors to detect the surface of the object being scanned and assigns data points to that surface. Those data points ultimately recreate the object. Depending on the type of laser, light, or sensor used, the level of detail and efficiency of making the scan can differ.
