Abstract
Multimaterial (MM) 3D printing shows great potential for application in metamaterials, flexible electronics, biomedical devices and robots, since it can seamlessly integrate distinctive materials into one printed structure. Among numerous MM 3D printing technologies, digital light processing (DLP) MM 3D printing is compatible with a wide range of materials from hydrogels to ceramics, and can print MM 3D structures with high resolution, high complexity and fast speed. This paper introduces the fundamental mechanisms of DLP 3D printing, and reviews the recent advances of DLP MM 3D printing technologies with emphasis on material switching methods and material contamination issues. It also summarizes a number of typical examples of DLP MM 3D printing systems developed in the past decade, and introduces their system structures, working principles, material switching methods, residual resin removal methods, printing steps, as well as the representative structures and applications. Finally, we provide perspectives on the directions of the further development of DLP MM 3D printing technology.
多材料(MM)三维打印在超材料、柔性电子器件、生物医学设备和机器人领域具有巨大的应用潜力,因为它可以将不同的材料无缝集成到一个打印结构中。在众多多材料三维打印技术中,数字光处理(DLP)多材料三维打印技术可兼容从水凝胶到陶瓷等多种材料,并能打印出高分辨率、高复杂度和高速度的多材料三维结构。本文介绍了 DLP 三维打印的基本机理,回顾了 DLP MM 三维打印技术的最新进展,重点介绍了材料切换方法和材料污染问题。本文还总结了近十年来开发的一些 DLP MM 三维打印系统的典型实例,介绍了它们的系统结构、工作原理、材料切换方法、残留树脂去除方法、打印步骤以及具有代表性的结构和应用。最后,我们对 DLP MM 三维打印技术的进一步发展方向进行了展望。
期刊介绍:
The International Journal of Extreme Manufacturing (IJEM) focuses on publishing original articles and reviews related to the science and technology of manufacturing functional devices and systems with extreme dimensions and/or extreme functionalities. The journal covers a wide range of topics, from fundamental science to cutting-edge technologies that push the boundaries of currently known theories, methods, scales, environments, and performance. Extreme manufacturing encompasses various aspects such as manufacturing with extremely high energy density, ultrahigh precision, extremely small spatial and temporal scales, extremely intensive fields, and giant systems with extreme complexity and several factors. It encompasses multiple disciplines, including machinery, materials, optics, physics, chemistry, mechanics, and mathematics. The journal is interested in theories, processes, metrology, characterization, equipment, conditions, and system integration in extreme manufacturing. Additionally, it covers materials, structures, and devices with extreme functionalities.
