Abstract

A printing head for a 3-D printing device comprises a nozzle arranged to print a layer of a printing material on a receiving surface, and a texturing member arranged to texture the layer or the receiving surface during printing of the layer. The nozzle comprises an outlet including the texturing member, and the outlet is shaped to form protrusions extending from a main surface of the layer for interlocking with a subsequent layer. The texturing member ensures that contacting layers formed with the printing head exhibit improved adhesion due to the increased contact surface area between the layers. This yields stronger printed 3-D articles. A printing apparatus including the printing head, a printing method and an article printed in accordance with the printing method are also disclosed.
