The successful development of fused deposition modeling (FDM) printing has stimulated significant market demand for colored poly(lactic acid) (PLA) filaments. However, dye- or pigment-based PLA filaments were susceptible to fading and toxicity risks. Hence, structurally urgently need be developed their ecofriendliness sustainability. Herein, we draw inspiration from the disordered structure fruit wax, which exhibits selective light scattering on surface blueberries. We utilize ZnS spheres supporting Mie covered granules, thereby endowing them with structural color. Structurally granules transformed into a uniform wire diameter homogeneous color through hot-melt extrusion method, used as materials FDM printing. fabricated 3D printed object an adjustable vivid color, demonstrating excellent resistance acids, alkalis, impacts, well recyclability, significantly enhances its potential applications.
