Abstract
A printer unit () 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 () comprising a nozzle (). The printer head is resiliently suspended in the printer unit in a vertical direction by at least one resilient means (), 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 (Δz) before deposition. During deposition of printing material, the at least one resilient means is configured to become biased by a vertical force (F) 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 (Δz) from the underlying material.
