    摘要: A method of providing a configuration of a system of interference filters with a visible color shifting effect, includes: a hue matching step of identifying a configuration of a first interference filter including two first metal layers and a first spacer layer therebetween, and a configuration of a second interference filter including two second metal layers and a second spacer layer therebetween, wherein the first and second filters match in hue at the first viewing angle, and the mismatch in hue at the second angle; and a lightness adjustment step which may include modifying the layer material or the layer thickness of one of the metal layers; wherein a difference in lightness at the first viewing angle between the first and second modified filters is less that a difference in lightness at the first viewing angle between the first and second filters.

    摘要: 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
