Method for manufacturing a 3D item (1) by means of fused deposition modeling, the method comprising layer-wise depositing (during a printing stage) 3D printable material (201), to provide the 3D item (1) comprising 3D printed material (202), wherein the 3D printable material (201) comprises a continuous phase of a thermoplastic polymeric material and particles (410) embedded therein, wherein the particles (410) comprise a crosslinked polymeric material and wherein the particles (410) have a first dimension (LI) selected from the range of 0.2-100 micron. The 3D printable material (202) and the particles (410) comprise a light transmissive material, and the light transmissive material of the particles (410) has an index of refraction selected from the range of 1.2-1.8
