The introduction of 4D printing has revolutionized the manufacturing industry. Current research indicates that 4D printing, although at a nascent stage, is a promising technology that brings immense benefits that will soon outweigh high initial costs. 4D technology is considered an upgrade of 3D printing technology by the introduction of the fourth dimension: time. It has been shown that printed 4D materials can adapt to different stimuli such as temperature, water, pH, and light. These stimuli allow for self-assembly, self-repair, and multiple functionalities in these materials, which yield enormous potential for critical applications of 4D printed materials in the medical and aerospace fields. This paper reviews the current state of 4D printing and includes the technologies, materials, shifting/deformation behaviors, applications, and challenges surrounding this innovative approach to manufacturing. Advantages of 4D over 3D are also highlighted and the novel 4D printing technology via automated fiber placement is discussed. This review offers an analysis of composite materials used in this technology and describes how transformations of these materials elevate 3D printing technology. By highlighting opportunities for further improvement of 4D printing and contributing its fundamental understanding, this review article concludes that 4D printing is a revolutionary technology that is here to stay.

4D打印材料和增强复合材料的评论:行为,应用和挑战

4D打印的引入彻底改变了制造业。当前的研究表明,尽管4D打印处于起步阶段,但它是一项很有前途的技术,它带来的巨大好处很快就会超过高昂的初始成本。通过引入第四个维度:时间,4D技术被认为是3D打印技术的升级。已经表明,印刷的4D材料可以适应不同的刺激,例如温度,水,pH和光。这些刺激允许这些材料中的自组装,自修复和多种功能,这为4D打印材料在医学和航空航天领域的关键应用提供了巨大的潜力。本文回顾了4D打印的当前状态,包括技术,材料,移动/变形行为,应用,围绕这种创新制造方法的挑战。还强调了4D相对于3D的优势,并讨论了通过自动纤维放置实现的新颖4D打印技术。这篇评论提供了对该技术中使用的复合材料的分析,并描述了这些材料的转变如何提升3D打印技术。通过重点介绍进一步改善4D打印的机会并贡献其基本理解,这篇综述文章得出的结论是4D打印是一项将持续存在的革命性技术。这篇评论提供了对该技术中使用的复合材料的分析,并描述了这些材料的转变如何提升3D打印技术。通过重点介绍进一步改善4D打印的机会并贡献其基本理解,这篇综述文章得出的结论是4D打印是一项将持续存在的革命性技术。这篇评论提供了对该技术中使用的复合材料的分析,并描述了这些材料的转变如何提升3D打印技术。通过重点介绍进一步改善4D打印的机会并贡献其基本理解,这篇综述文章得出的结论是4D打印是一项将持续存在的革命性技术。
