3D Printing Method Creates Shape-Shifting Objects

Components will be designed from the onset to inhabit multiple configurations during service

(Georgia Tech News Center: Atlanta) -- A team of researchers from Georgia Institute of Technology and two other institutions has developed a new 3D printing method to create objects that can permanently transform into a range of different shapes in response to heat.

The team, which included researchers from the Singapore University of Technology and Design (SUTD) and Xi’an Jiaotong University in China, created the objects by printing layers of shape memory polymers with each layer designed to respond differently when exposed to heat.

“This new approach significantly simplifies and increases the potential of 4D printing by incorporating the mechanical programming post-processing step directly into the 3D printing process,” says Jerry Qi, a professor in the George W. Woodruff School of Mechanical Engineering at Georgia Tech. “This allows high-resolution, 3D printed components to be designed by computer simulation, 3D printed, and then directly and rapidly transformed into new permanent configurations by simply heating.”
