Sustainable 3d printed sparkle and hide structure

Abstract

The invention provides a method for producing a 3D item by means of fused deposition modelling, the method comprising: a 3D printing stage comprising layer-wise 3D printable material, to provide the 3D item comprising 3D printed material, wherein the 3D item comprises a plurality of layers of 3D printed material, wherein: (a) the method comprises generating a stack comprising n layers of 3D printed material on top of each other by depositing 3D printable material along n printing paths (APn), wherein the n printing paths (APn) and printing conditions are selected such that the stack comprises stack sections and stack modulations; (b) for the stack sections applies: (i) an nth layer is configured on an (n−1)th layer and/or (ii) the (n−1)th layer is configured on an (n−2)th layer; (c) for (at least part of) the stack modulations applies: an nth layer is partly configured on an (n−1)th layer and partly on an (n−2)th layer, and the (n−1)th layer is partly configured between the nth layer and the (n−2)th layer; and (d) n>3, and the 3D printable material comprises a light transmissive material.
