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 ...

The Singapore University of Technology and Design (SUTD) and its research collaborators have successfully demonstrated the four-dimensional (4D) printing of shape memory polymers in submicron ...

(Nanowerk News) Printed polymers that change shape once in a predefined way when heated? This is now possible thanks to a 4D printing technology developed in the Fraunhofer Cluster of Excellence ...

(MENAFN- EIN Presswire) EINPresswire/ -- Minimally invasive medical implants require materials that can be delivered in compact form and recover their functional shape once inside the body. However, ...

Shape memory polymers (SMPs) are a remarkable class of stimuli‐responsive materials capable of undergoing substantial deformation and subsequently recovering their original shape when exposed to ...

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 ...

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 ...

Marc del Pozo Puig of the Eindhoven University of Technology (TU/e) has created a new 'smart ink' for use in 4D printing. 4D printing uses 3D printing to create objects capable of rearranging ...

4D printing introduces the "time dimension" based on 3D printing, enabling printed structures to undergo controllable dynamic changes in shape, properties, or functions under external stimuli such as ...

4D printing takes 3D printing a step further to create objects that can move or reconfigure themselves on demand once fabricated. While it is still in its nascent stages, researchers at Rice ...

The microscopic creatures like geckos and octopuses fabricated by 3D laser printing could open up new opportunities in fields such as microrobotics or biomedicine. These 'life-like' 3D microstructures ...
