A new 3D printing method has enabled researchers to create objects that can permanently transform into a range of different shapes in response to heat.
A research team that included the Georgia Institute of Technology, Singapore University of Technology and Design and Xi’an Jiaotong University in China have 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,” Jerry Qi, a professor in the George W. Woodruff School of Mechanical Engineering at Georgia Tech, said in a statement.
