Abstract: A method of additive manufacturing of an object may include directing laser energy from a laser to a region for material deposition, extruding material using an extruder at the region of material deposition, sensing temperature within the region of the material deposition, and electronically controlling the laser energy using the temperature so as to sufficiently heat the region for material deposition prior to extruding the material to increase strength of the object. The method may include hardening or freezing extruded material through cooling in real-time.
