A method for applying a 2d pattern onto a 3d object

Abstract

The present invention relates to a method for producing a 3D item (1) by means of fused deposition modelling, the method comprising the step of: a) layer-wise depositing a first 3D printable material (4) and a second 3D printable material (5) to provide the 3D item (1) comprising a layer stack (2) having an exposed surface (3), wherein the first 3D printable material (4) has a first polarity and a first porosity; wherein the second 3D printable material (5) has a second polarity and a second porosity; the first polarity being different from the second polarity and/or the first porosity being different from the second porosity; wherein the first 3D printable material (4) forms a first surface portion (4′) of the exposed surface (3) of the layer stack (2), and the second 3D printable material (5) forms a second surface portion (5′) of the exposed surface (3) of the layer stack (2); wherein the method further comprises the step of: b) applying a coating (7) on the second surface portion (5′) of the exposed surface (3) of the layer stack (2).
