LASER HEATING CONTROL MECHANISM, LASER HEATING CONTROL METHOD, LASER HEATING CONTROL PROGRAM, AND THREE-DIMENSIONAL SHAPING APPARATUS

摘要

A laser heating control mechanism according to this invention is a mechanism that performs proper adjustment of preheating or postheating by a simple operation in three-dimensional shaping. The laser heating control mechanism is a laser heating control mechanism for preheating or postheating a heating target object. The laser heating control mechanism includes an optical fiber that transmits a laser beam and radiates the laser beam from an opening end face, a collimation optical system that fucuses the laser beam radiated from the opening end face onto the heating target object, and an irradiation range adjustment mechanism that adjusts the distance between the opening end face and the collimation optical system along the irradiation axis of the laser beam so as to irradiate the heating target object with the laser beam at a predetermined beam diameter.
