Abstract: A method and system for a three dimensional printing system are described herein. In one example, the three dimensional printing system has a moveable carriage, an array of laser modules and a print controller. In this example, the moveable carriage has a print head arranged to selectively deposit a printing agent on to a layer of build material as the moveable carriage is moved relative to the layer of build material. The printing agent controls localized fusing of the build material on application of energy. The print controller is communicatively coupled to the array of laser modules and controls activation of individual laser modules of the array of laser modules so as to apply, selectively, energy to addressable sub-regions of the layer of build material on which printing agent has been deposited to control fusing together with the deposited printing agent.

Abstract: A printing unit comprises a movable carriage being movable along a path and having a plurality of energy emitters arranged in an array, a controller to control a supplied energy level of the emitters, and a sensor unit to measure an emitted energy level of each emitter, wherein the controller is to compare the measured energy level with a target energy level associated with the supplied energy level to obtain and to generate a matrix indicating a compensation value for each emitter based on the comparison result so as to calibrate the energy level of comparison result.
