The interweaving of polymeric materials with multiscale, multimaterial 3D printing processes could enable the additive manufacturing of a diverse set of complex, multifunctional structures. To this end, the focus of this talk is to introduce the 3D printing of presurgical organ models, cardiac muscle pump, and smart electronics with unique geometries and extraordinary functionalities that can be utilized for biomedical and healthcare applications. Firstly, 3D printed, patient‐specific prostate and aortic root models with physical properties of tissue and integrated capacitive sensors will be presented and their applications in surgical rehearsal and planning, medical device evaluation, and postoperative complication prediction will be discussed. Secondly, 3D bioprinting of cardiac muscle pump using stem cell‐laden biomaterials and in situ proliferation and differentiation procedure will be presented. The muscle pump exhibits contiguous muscle wall and macroscale beating function. Thirdly, a 3D printed stretchable piezoresistive tactile sensor fabricated on freeform surface under mild conditions using customized electronic materials will be introduced. This sensor can be integrated onto human skin for health monitoring and motion detection. Finally, my future research and teaching plans about additive manufacturing, functional materials and devices, and their applications at the Washington State University will be briefly discussed in the talk.


Dr. Kaiyan Qiu is currently a Postdoctoral Associate in Mechanical Engineering at the University of Minnesota. He received his Ph.D. in Fiber Science with Polymers and Biological Engineering Concentrations from Cornell University, and completed his Bachelor and Master Degrees from Donghua University. During his Ph.D. at Cornell, Dr. Qiu worked on biobased and biodegradable polymer composites in Prof. Anil Netravali’s group. He also spent a year at Dartmouth College for studying freeze‐cast biomaterials. After that, Dr. Qiu joined Prof. Michael McAlpine’s group at Princeton University and University of Minnesota. With his expertise in functional materials, additive manufacturing (3D printing), electronics, and biotechnologies, Dr. Qiu’s recent work focuses on designing and developing presurgical organ models with integrated electronics for surgical rehearsal and medical device evaluations, flexible electronics for health monitoring, and cardiac tissue models for biomedical applications. His highly interdisciplinary research work has been published in numerous high‐impact journals. The work also represents several first and has been widely recognized in scientific news outlets.
