Laser scanning can be used to record a three-dimensional computer model of an object, often for CAD modelling, but also for part inspection or defect monitoring. A laser is used to take spot measurements in three dimensional space of an object. This can be done using a handheld or mounted scanner that revolves around the object while it is stationary. Once scanned, a computer file is created that can be used for 3D printing, further CAD work, or other digital steps.
