Beschreibung
Zusammenfassung:	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. The suspended printer head in its equilibrium is positionable above the underlying material at a vertical distance (Δz1) before deposition. During deposition of printing material, the at least one resilient means is configured to become biased by a vertical force (F3) on the nozzle from the printing material on the underlying material, such that the printer head moves from its equilibrium into a position at a desired vertical distance (Δz1) from the underlying material.
