1. A temperature control system for additive manufacturing, the system comprising:
a cladding device configured to fuse a material and form a cladding layer, the cladding device comprising a first energy source configured to direct an energy beam toward the material for fusing at least a portion of the material to form the cladding layer;
a micro-forging device coupled to the cladding device for forging the cladding layer;
a detecting device configured to detect a first internal effect parameter of the cladding layer at a forging position where the cladding layer is forged by the micro-forging device, wherein the first internal effect parameter includes at least one of a stress or a strain of the cladding layer;
a control module configured to receive the first internal effect parameter detected by the detecting device, and calculate a first calculated temperature at the forging position based on the first internal effect parameter; and
an adjusting module coupled to at least one of the first energy source and the micro-forging device and configured to receive the first calculated temperature and to adjust the at least one of the first energy source and the micro-forging device to make the first calculated temperature at the forging position fall within a desired temperature range if the first calculated temperature does not fall within the desired temperature range.
