Patent number: 11273597Abstract: A printer unit (100) for a 3D-printing apparatus for deposition of a printing material, as well as a method of 3D printing, is provided. The printer unit comprises a printer head (105) comprising a nozzle (110). The printer head is resiliently suspended in the printer unit in a vertical direction by at least one resilient means (120), allowing a vertical movement of the printer head during deposition of the printing material.
