Exploring the Frontiers of 4D Printing

A new printer could change manufacturing by creating self-assembling structures that can change shape after being exposed to heat and other stimuli. Dubbed “4D Printing” — the extra “d” refers to the time of self-assembly — this technology could have significant aerospace, medicine, and other industries. It could, for example, one day allow manufacturers to produce electronic devices and their wiring in a single process.

In this video, H. Jerry Qi, Ph.D., of the Georgia Institute of Technology, discusses this technology at the 255th ACS National Meeting & Exposition in New Orleans. He explains recent breakthroughs in the field and discusses some of the technology’s potential applications.
