Advanced inorganic components, ceramics in particular, be them with micro pores or macro structs, either in a lattice or an irregular form, have been extensively used in advanced applications, ranging from load-bearing parts, bone implants, catalytic filters, to functional device components, due to their promising chemical and biological stability, and robust physical properties such as electrochemical, acoustic, optical, and magnetic characteristics. In this presentation, we report current advances of structural and functional inorganic ceramic components prepared with an integrated design and 3D printing approach in our institute (AMI-SZU), with a main focus on the photopolymerization 3D printing using UV light. Honeycomb structures of cordierite are fabricated using DLP polymerization-based 3D printing technique for gas purifier use. Ordered lattice structures of polymer-derived ceramics, such as ZrOC and SiOC, are fabricated via DLP 3D printing technique as well for structural uses and microwave absorption uses. Lattice structures of Li4SiO4 are fabricated for tritium breeding used in fusion reactors. Porous thin layers of perovskite LSCF are fabricated using inkjet printing as electrodes used in SOFCs. Porous Li-based structures are fabricated using low temperature direct ink writing as electrodes used in LIBs. The principle, advantages and drawbacks of each 3D printing techniques involved are described in detail and the performance and properties of relevant ceramic components fabricated are discussed.

Magnetic resonance imaging (MRI) is an important imaging modality for diagnostic and therapeutic purposes. However, it is only available to less than 30% of the world population due to the high cost and/or immobility. Portable MRI is compact with light weight and a small footprint, and is low cost. Its compactness makes MRI available to the bedside of a patient, and to the sites, e.g., in an ambulance and a medical tent in a war zone. The low cost makes MRI more available to the under-develop counties and regions. Additive printing plays a key role for fast prototyping of the key components of a portable MRI system. In this talk, how additive printing can help with magnet assembly, constrcutions of radiofrequency coil and gradient coils will be introduced. With the help of additive printing, building an MRI scanner becomes possible even in a school and in resource-scarce regions, which may further enhance the accessibility of portable MRI and MRI education, leading to democratization of MRI.     

Shao Ying HUANG is an associate professor in Singapore University of Technology and Design. She is an adjunct associate professor in the department of surgery in National University of Singapore, Singapore. She received her Ph.D. degree from Nanyang Technological University and Massachusetts Institute of Technology in 2011. Her background is electromagnetics and electromagnetic compatibility. She is one of the pioneers who pushes forward the innovations on MRI hardware to make MRI portable and accessible. She owns 8 patents and 6 technology disclosures and numerous refereed journal papers and international conference papers.
