Printhead for a 3d printer and a method for filling a printhead

Abstract

The invention relates to a printhead (100) for a 3D printer, comprising an actuator device (110) which is arranged in a housing (1) of the printhead (100) for actuating a piston (3), a supply device (2) for a printable material (10), a flange (5) which is arranged on the housing (1) and the supply device (2) and which comprises a cooling device (50), a nozzle head (6) with heating elements (61, 63) in order to convert the material (10) from a solid phase (10) to a liquid phase (12), and a nozzle (8) for discharging the liquid phase (12) of the material (10) out of the nozzle head (6). According to the invention, the solid phase (10) of the material has granulate particles (10) and the supply device (2) has a blowing device (25) for releasing the granulate particles (10) from one another. The invention additionally relates to a method (210) for filling a printhead (100), wherein a heatable cavity (40) of the printhead (100) is filled with printable material (10) by means of the supply device (2).
