Abstract: A printer head (100) for a 3D-printing apparatus, comprising a nozzle (110) arranged to deposit at least one filament (120) of a printing material in a direction (D) of movement of the printer head along an axis (A). The printer head further comprises at least one element (130) arranged adjacent said nozzle, wherein the at least one element further being arranged downstream of said nozzle with respect to the direction (D) and arranged at a distance (d) perpendicular to the axis (A). The at least one element is configured to be brought into abutting contact with at least one longitudinal side of the at least one filament during deposition of the at least one filament and configured to flatten at least a portion of the longitudinal side of the at least one filament.
