1. A method for manufacturing a 3D item by means of fused deposition modeling, the method comprising layer-wise depositing a 3D printable material with particles embedded therein,
wherein the 3D printable material comprises a continuous phase of a thermoplastic polymeric material,
wherein the particles comprise a crosslinked polymeric material,
wherein at least part of the total number of the particles have a first dimension (L1) selected from the range of 0.2-100 μm, the first dimension (L1) being a length or a diameter,
wherein the 3D printable material and the particles comprise a light transmissive material, and
wherein the light transmissive material of the particles has an index of refraction selected from the range of 1.2-1.8.
