Temperature control system for additive manufacturing and method for same

A temperature control method for additive manufacturing, the method comprising:

• a) directing an energy beam of a first energy source toward a material and fusing at least a portion of the material to form a cladding layer;
• b) forging the cladding layer with a micro-forging device;
• c) detecting an amplitude of the micro-forging device that is forging the cladding layer and determining a strain of a forging position based on the amplitude;
• d) calculating a first calculated temperature at the forging position based on the strain and a strain versus temperature curve;
• e) determining whether the first calculated temperature at the forging position falls within a desired temperature range, if yes, executing steps g) to i), if not, executing steps f) to i);
• f) adjusting the first energy source and the micro-forging device to make the first calculated temperature at the forging position fall within the desired temperature range;
• g) detecting an axial load of a main axis of a cladding device applied by the micro-forging device and determining a stress at the forging position based on the axial load;
• h) calculating a second calculated temperature at the forging position based on the stress and a stress versus temperature curve;
• and
• i) determining whether the second calculated temperature at the forging position falls within the desired temperature range, if yes, adjusting end, if not, updating the strain versus temperature versus curve and the stress versus temperature curve based on an adaptive algorithm and processing back to step c).
