Biography

Prajwal Agrawal is currently a Research Associate at ETH Zurich, Switzerland working with Prof. Daniel Ahmed on developing cutting-edge fabrication technologies for acoustics robotics, (bio)fabrication, precision medicine, and additive manufacturing. Previously he worked as a research assistant in Prof. Shrike Zhang’s group at Harvard Medical School and Brigham's and women's hospital, USA working towards fabricating and developing novel techniques for bioprinting and tissue engineering, especially for orthopedic, colloidal photonic crystals, and other applications. Having completed his undergraduate studies at Harvard University in the USA and VIT Vellore in India, he has a B.Tech. degree in Mechanical (Major) and Civil (Minor). Since May 2017, he has worked at the Manufacturing Department, VIT campus. Here, his research focused on the fabrication and analysis of metals, natural fibers, composites, and other materials. For this, he has been awarded G.D. Naidu Young Scientist Award, the Achievers award, and C.V. Raman Award by VIT for his outstanding academic and co-curricular performance. Moreover, he has been awarded third place for the best poster award at the MaP Graduate symposium, 2022. Besides academics, he has collaborated with companies such as Bosch, Mahindra Rise, Natural's Sugar LTD, and others. Among his publications are 10+ papers in high-impact peer-reviewed journals, such as Materials Today, Nature Communications, Small Structures, Applied Physics Reviews, Advanced Nano Biomed Research, and others. He has also written two book chapters. In addition, he has written a editorial and 4+ conference papers. Furthermore, he serves as a reviewer for several journals published by Springer Nature and Elsevier. He was recently awarded the Bridge Proof of Concept grant for realization of his project.

Abstract

As additive manufacturing has become more prevalent, 3D (bio)printing has attracted many researchers for its potential application in tissue engineering, regenerative medicine, composite manufacturing, and among others. Although 3D (bio)printing has a number of advantages, its speed is limited due to the fact that it can be printed in 0D, 1D, and 2D. In order to overcome this situation in 2019, Kelly et al. have developed Volumetric Printing, which allows objects to be printed in 3D using CT and IMRT scan mechanisms. The use of volumetric printing is currently limited to a single material and to the use of viscous inks and materials due to its relative newness. In my presentation, I will introduce our novel methodology to overcome the disadvantage of volumetric 3D (bio)printing for their utilization in composite, tissue, food, and other industries.
