• University of Utah Develops Holographic 3D Printer That Completes Prints in 20 Seconds July 10
Additional Context
University of Utah engineers have built a holographic 3D printer that produces complete shapes in a single exposure rather than building them layer by layer, eliminating the structural seams that weaken conventionally printed parts. The process takes about 20 seconds, compared to the hours required by other laser-based printing methods.
The research, led by Rajesh Menon, professor of electrical and computer engineering at the Price College of Engineering, and lab member Dajun Lin, was published June 4 in Nature Communications under the title “Single-exposure holographic lithography of ultra-high aspect-ratio microstructures.” Brian Baker of the Utah Nanofab is a co-author, and the National Science Foundation and the University of Utah funded the work.
The technique uses a nanopatterned m
