报告摘要：

The rapid advanced 3D printing technique provides unprecedented freedom of design and manufacturing and allows us to fabricate complex 3D structures and devices with soft active materials. The technique of printing 3D structures with smart materials that change configurations over time also refers to as “4D printing”. In this talk, I will first introduce a new paradigm of printed active composites (PACs) that is realized by printing composites with complex and controllable anisotropic thermomechanical behavior via prescribing the architecture, shape, size, orientation and even spatial variation of the fibers with shape memory effects. To overcome main limitations of using commercial 3D printers, i.e. the material selections and costs, a new multi-material micro 3D printing technique is developed for soft smart materials - projection micro-stereolithography (PμSL), which enables us to create freely tunable material properties with inexpensive commercially available polymers and fabricate highly deformable complex 3D devices with smart materials.
