4D打印技术的研究进展

Progress on 4D Printing

3D打印技术具有能够方便廉价地实现从3D虚拟模型到实体化的优点,在产品设计、快速成型、先进材料等领域得到了广泛的应用。近年来,"4D打印"概念的提出引起了社会和学术界广泛的关注。4D打印技术是在3D打印的基础上引入时间维度,在一定外界刺激的作用下,4D打印刺激响应材料的形状、结构和功能能够随着时间的推移而不断变化。文中对4D打印进行了概述,着重介绍了4D打印材料及其形状记忆效应,总结了4D打印技术在各个领域的应用前景,并结合4D打印研究现状探讨了4D打印技术的发展趋势。

3D printing technology has been widely used in the fields of product design,rapid prototyping,and advanced materials for its advantages of convenience and cheapness to fabricate three-dimensional objects.In recent years,the concept of“4D printing”has attracted widespread attention from the society and academia.On the basis of 3D printing,4D printing technology introduces the dimension of time.Under the influence of certain external stimuli,the shape,structure and function of 4D printing stimuli-responsive materials can change over time.This paper gave an overview of 4D printing,highlighted 4D printing materials and their shape memory effects,summarized the application prospects of 4D printing technology in various fields,and discussed the development trend of 4D printing technology in combination with the current research status of 4D printing.
