  • Printing head assembly for a 3D printer and a 3D printer with this assembly
    Patent number: 12415314
    Abstract: A 3D printer printing head assembly comprises a printing head carrier and a printing head, which comprises at least two printing units implemented such that they are mutually offset in the print plane. Each printing unit comprises an extruder, filament feeder, cooling mechanism, and nozzle. The printing units at a mutual spacing are adapted for simultaneous printing in different, mutually offset print planes. This assembly therefore allows for printing in multiple planes simultaneously. Furthermore, the object of the invention is a 3D printer with this assembly.
