(Nanowerk Spotlight) Compared to creating static objects with 3D printing, 4D printing systems add time as the fourth dimension to 3D printing: 4D printing allows a 3D printed structure to change its ...

Chinese researchers have developed a biodegradable shape memory polymer (SMP) using 4D-printing technology that is suitable for medical devices, according to the Lanzhou University. This was reported ...

4D printing enables 3D printed structures to change its configurations over time and is used in a wide variety of fields such as soft robotics, flexible electronics, and medical devices. Different ...

A recent article published in Small Science introduces fully bioderived, four-dimensional (4D) printable shape memory polymers (SMPs) with linear tunability and remotely controlled actuation ...

Imagine a single piece of material that can change its shape, stiffness, and function—on demand—like a Swiss Army knife made of plastic. That's what researchers at the Harbin Institute of Technology ...

A joint research team led by Dr. Dong-Gyun Kim of the Korea Research Institute of Chemical Technology (KRICT), Professor ...

3D printing is well understood and ubiquitous by now but not many may know of 4D printing. To put it simply, 4D printing is the process by which a 3D-printed object transforms itself into another ...
