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.
