1. A method of formfree printing a three-dimensional object in layers with at least one printing material, the method comprising:
outputting printing material in at least one printing material string in string-shape via at least one printing head;
receiving, via a printing platen, at least one printing material string output by the at least one printing head;
providing a rod-shaped heating device movably arranged over the printing platen, wherein the rod-shaped heating device has a length of the same or higher than the width of the printing platen;
controlling the rod-shaped heating device, via a heat controller, to emit a heat irradiation directed to the printing platen to heat the at least one printing material string to a reaction temperature to trigger a chemical reaction of the at least one printing material of the at least one printing material string;
providing at least one motor coupled to the rod-shaped heating device to move it over the printing platen; and
controlling the at least one motor, via a motor controller, to move the rod-shaped heating device over the printing platen to harden the at least one printing material string printed on the printing platen.
