Abstract (en)
[origin: WO2022195027A1] The invention relates to a method (200) for providing a printable melt (12) for operating a printhead (100) for a 3D printer. According to the invention, the method (200) has the following steps: - filling (210) a cavity (40) with printable material (10) using a supply device (2), - closing (220) an opening cross-section (21) of a piston bushing (4) by advancing a piston (3) from a starting position (3a) in the direction of a nozzle (8) of the printhead (100), - converting (230) the material from a solid phase (10) to a liquid phase (12) via a plastic phase (11), - solidifying (240) the material (10, 11, 12), - ascertaining (250) a spring constant of the liquid phase (12), and - preparing (260) the liquid phase (12) for a printing process. The invention also relates to a printhead (100) for a 3D printer for carrying out the method (200) according to the invention.
