Patent ID: 10780654

Abstract:
The invention provides a method for 3D printing a 3D item (1), the method comprising depositing during a printing stage 3D printable material (201), to provide the 3D item (1) comprising 3D printed material (202), wherein the printing stage comprises: —3D printing a first 3D printable material (201a) to provide a first 3D printed material (202a), the first 3D printable material (201a) comprising a cross-linkable material; —creating a relief structure (610) in the first 3D printed material (202a) with a tool (630); and —3D printing a second 3D printable material (201b) to provide a second 3D printed material (202b), to provide a stack (620) of (i) 3D printed material (202) comprising the first 3D printed material comprising the relief structure (610), and (ii) the second 3D printed material (202b), wherein the method further comprises: —cross-linking at least part of the first 3D printed material (202a) comprising the relief structure (610) before depositing the second 3D printable material (202b).
