3D and 4D Printing: High Performance and Stimuli-Responsive Polymer Materials

The advent of 3D printing has enabled prototypes and devices of high-performance polymeric materials which have appended functionality based on composition and macromolecular design. 3D printed polymers can be further classified into thermoplastics, thermosetsond elastomers based with their corresponding thermo-mechanical properties. However, using multi-materials and 4D printing allows the design of new materials and applications based on integrating conversion chemistry with the printing mode. This talk will demonstrate stimuli-responsive properties and 4D fabrication of multi-materials, including epoxy and benzoxazine thermosets and silicone elastomers with concept objects and elastomeric properties exhibiting stimuli-response. While most of the method focuses on DIW or viscous solution printing (VSP), other works using SLA, SLS, and FDM 3D Printing will also be revealed.
