To clarify: 4D printing is using computerized printing technologies to 3D print objects using specialist materials that change shape, properties, and functions in time when exposed to a specific stimulus.
A duo presentation by Frederic Demoly, Associate Professor at Université Bourgogne Franche-Comté, UTBM and Jean-Claude Andre, CNRS.
Over the past decades, the combination of technical/scientific advances in additive manufacturing (AM) and smart materials (SMs) domains has enabled the booming development of a new interdisciplinary converging research area: 4D printing.

Hygromorph BioComposites (HBC) are categorized into a new class of smart materials that could be used for 4D printing of shape-changing mechanisms. Fibre anisotropic properties, fibre content and their orientation, polymer stiffness are material parameters that control the morphing. Slicing parameters during 4D printing such as Layer Height and various Interfilament Distance enable a programmation of the hygromorph biocomposites response. The potential of sequential complex actuation will be discussed.
Researchers have created a 3D printer-compatible hydrogel that is mechanically tough and able to repeatedly change shape in response to water temperature. The scientists have demonstrated the technology by 3D-printing an autonomous water valve, …. Continue reading “New “4D-printing” material can change shape in hot water”
