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.

一缸多材料3D打印:魔鬼在细节
大自然将不同的材料结合在单一结构中,以实现单一材料无法单独完成的功能,这种方法激发了构建具有精确定制性能的合成系统的努力。还原光聚合技术(VPP)可以实现快速、高分辨率的3D打印,但大多数打印部件仍然只使用一种材料。本展望重点介绍了单缸多材料VPP的新兴策略,其中光选择性地激活不同的化学反应,以多种材料构建复杂的结构。关键的进展将取决于将树脂化学扩展到标准丙烯酸酯之外,提高反应选择性,以及使用灰度和多波长光控制来定义材料形成的位置和方式。标准化的机械、热和界面测试方法对于确保可靠的结果至关重要。随着化学、光学和数据驱动设计的进步,多材料VPP可以在医学、制造业和航空航天领域开启变革性应用。刺激选择性树脂为快速、高分辨率的多材料3D打印提供了关键机会。本展望强调了在化学、加工和表征方面需要取得的进展。

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.
