Scientists from NUST MISIS have created a composite shape memory material for 4D printing

Researchers at the MISIS University have developed a new magnetically sensitive polymer composite material that is promising for 4D printing, a technology in which materials can change their shape over time. The material is also suitable for creating adaptive medical devices, such as soft tissue fixators and “self-setting” bone implants. The composite, consisting of polylactide and cobalt ferrite, has the ability to heat up quickly under the influence of a high-frequency alternating magnetic field and recover its shape well after deformation, without causing harmful effects on the body.
