The concept of 4D printing isn't a new idea, but processes that use new types of environmental stimuli keep on appearing. 4D printing is usually defined as 3D printing with materials that change shape ...

Shape-memory polymers or shape-shifting materials are smart materials that have gained significant attention within materials science and biomedical engineering in recent years to build smart ...

Engineers from MIT and Singapore University of Technology and Design (SUTD) are using light to print three-dimensional structures that "remember" their original shapes. Even after being stretched, ...

Ordinarily, if you want to change the shape in which an object is 3D-printed, you have to alter the computer model that tells the printer what to do. A new and simpler technique, however, allows the ...

To print shape-memory structures with even finer details, Fang and his colleagues used a 3-D printing process they have pioneered, called microstereolithography, in which they use light from a ...

The shape-memory polymer was used to 3D-print several structures, including a replica of the Eiffel tower. Microstereolithography, pioneered by the researchers, uses light from a projector to print ...

An Oregon State University researcher has helped create a new 3D printing approach for shape-changing materials that are likened to muscles, opening the door for improved applications in robotics as ...
