Abstract
(DE)
Ein Druckkopf (100) zur Herstellung 3 -dimensionaler Formkörper in einem 3D-Drucker, mindestens aufweisend eine Zuführeinheit (300) für ein Filament (200), eine Aufschmelzeinheit (400) zum Aufschmelzen des Filaments (200) und eine Druckkopfdüse (500), zeichnet sich dadurch aus, dass die Zuführeinheit (300) und die Aufschmelzeinheit (400) eingerichtet sind, um ein asymmetrisches Filament (200) mit einem Aspektverhältnis von ≥ 1,5 und ≤ 1000 zu verarbeiten und dass zwischen der Zuführeinheit (300) und der Aufschmelzeinheit (400) eine Kühleinheit (600) angeordnet ist, durch welche hindurch das Filament (200) zur Aufschmelzeinheit (400) geführt wird.
(EN)
The invention relates to a print head (100) for producing 3-dimensional shaped bodies in a 3D printer, at least having a feeder unit (300) for a filament (200), a melting unit (400) for melting the filament (200) and a print head nozzle (500), characterized in that the feeder unit (300) and the melting unit (400) are designed to process an asymmetrical filament (200) having an aspect ratio of ≥ 1.5 and ≤ 1000 and in that a cooling unit (600) is arranged between the feeder unit (300) and the melting unit (400), through which cooling unit the filament (200) is guided to the melting unit (400).
