MedShape (Atlanta, GA) has been granted a U.S. patent for a shape memory polymer-based technology used in orthopedic applications. Shape memory polymers can "remember" more than one shape and ...

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 ...

Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although ...

With 4D printing, the objects can change shape or properties using external stimuli such as temperature, light, pH, magnetic field, electricity, and moisture. Additionally, the changes in shape or ...
