MOMENTUM • VIRGINIA TECH MECHANICAL ENGINEERING 29 bring new , stronger ceramic micro-architectures to market still lay in the future . Currently , 3D printers produce structures at the micrometer level , but printing ceramics still requires firing the final product , which possibly introduces many uncontrolled tiny pores and cracks . These defects make the structures extremely fragile . Li hopes that continued advances in the field of 3D printing and further understanding of the formation mechanisms of biological structures like starfish skeletons eventually offers a solution .
“ Nature is able to assemble mineral precursors to form complex architectures at room temperature and ambient pressure ,” Li said . “ That is something that modern human technology cannot currently achieve . Virginia Tech has a strong research interest in mineral structures found in nature , and I am hopeful that this exciting research direction may one day lead to the development of a wide range of bio-inspired , stronger , and more lightweight materials .”
