Abstract
Nature combines different materials in a single structure to achieve functions that no single material could accomplish alone, an approach that inspires efforts to build synthetic systems with precisely tailored properties. Vat photopolymerization (VPP) enables fast, high-resolution 3D printing, but most printed parts still use only one material. This Outlook highlights emerging strategies for single-vat multimaterial VPP, where light selectively activates different chemical reactions to build complex structures with multiple materials. Key advances will depend on expanding resin chemistry beyond standard acrylates, improving reaction selectivity, and using grayscale and multiwavelength light control to define where and how materials form. Standardized mechanical, thermal, and interface testing methods are essential for ensuring reliable results. With advances in chemistry, optics, and data-driven design, multimaterial VPP could unlock transformative applications in medicine, manufacturing, and aerospace.
Stimuli-selective resins offer key opportunities for fast, high-resolution multimaterial 3D printing. This Outlook highlights advances needed in chemistry, processing, and characterization.
期刊介绍:
ACS Central Science publishes significant primary reports on research in chemistry and allied fields where chemical approaches are pivotal. As the first fully open-access journal by the American Chemical Society, it covers compelling and important contributions to the broad chemistry and scientific community. "Central science," a term popularized nearly 40 years ago, emphasizes chemistry's central role in connecting physical and life sciences, and fundamental sciences with applied disciplines like medicine and engineering. The journal focuses on exceptional quality articles, addressing advances in fundamental chemistry and interdisciplinary research.
