Abstract
A printing head () for a 3-D printing device is disclosed that 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 said 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 3-D articles printed in this manner. A printing apparatus including the printing head, a printing method and an article printed in accordance with the printing method are also disclosed.
