Abstract

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 colored PLA filaments urgently need to be developed for their ecofriendliness and sustainability. Herein, we draw inspiration from the disordered structure of the fruit wax, which exhibits selective light scattering on the surface of blueberries. We utilize ZnS spheres supporting Mie scattering covered PLA granules, thereby endowing them with structural color. Structurally colored PLA granules were transformed into PLA filaments with a uniform wire diameter and homogeneous structural color through the hot-melt extrusion method, which were used as materials for FDM printing. The fabricated 3D printed object exhibits an adjustable and vivid structural color, demonstrating excellent resistance to acids, alkalis, and impacts, as well as recyclability, which significantly enhances its potential applications.

期刊介绍： ACS Applied Materials & Interfaces is a leading interdisciplinary journal that brings together chemists, engineers, physicists, and biologists to explore the development and utilization of newly-discovered materials and interfacial processes for specific applications. Our journal has experienced remarkable growth since its establishment in 2009, both in terms of the number of articles published and the impact of the research showcased. We are proud to foster a truly global community, with the majority of published articles originating from outside the United States, reflecting the rapid growth of applied research worldwide.
