Abstract
An additive manufacturing device calibration system and method. In laser control systems, such as the laser control systems used for SL and SLS 3D printers, the laser beam is moved to a location by applying a control value. Often the control value and the location of the laser beam are in different spaces. One calibration system and method involves the input of a number of control values and their corresponding laser beam locations, and the adjusting of the parameters of a mapping function such that the control values generated by applying the mapping function to the input laser beam locations best matches the corresponding input control values.
