%X 4D打印技术是基于智能材料与结构的增材制造技术提出来的,4D打印制造的实体结构形状可以随外界环境发生变化。通过对形状记忆合金、形状记忆聚合物、压电材料、电致活性聚合物、光驱动型聚合物、水驱动结构等智能材料与结构的增材制造方法与驱动效果进行综合比较发现:直写打印成型具有适用性广的特点,单一智能材料的驱动性能有限;混合增材制造技术可以兼具多种智能材料的性能,拥有多种原位驱动模式,能够克服单一智能材料与结构的不足。文献综述表明:4D打印技术研究整体还处于实验室探索阶段;4D打印还需要在拓宽智能材料范围、开发打印软件、探索打印工艺、研究软材料打印方法、解决不同智能材料的兼容问题等方面展开深入研究,才能够在医疗、军事、航天等领域得到广泛应用。<br>4D printing technology is proposed based on 3D printing technology of smart materials and structure. 4D printed entities can be changed with the external environment. The method of additive manufacturing and driving effect of materials, such as shape memory alloys, shape memory polymers, piezoelectric materials, electroactive polymers, light driven polymer and water drive structure, are compared and it is concluded that direct writing printing has the characteristics of wide applicability, while driving performance of a single smart material is limited. Multi？？material additive manufacturing can combine many kinds of smart materials with many kinds of drive mode and overcome the shortage of single smart material and structure. The literature review shows that 4D printing research is still in the laboratory stage, it is also required to broaden the intelligent materials, develop the printing software, explore the printing process, investigate the methods for soft materials and solve the problems in intelligent material compatibility, in order that 4D printing can be widely used in medicine, military, aerospace and other fields
