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.

A presentation by Mahdi Bodaghi, Nottingham Trent University.
Recent advances in AM created 4D printing technology as an emerging technology for crafting meta-materials and smart devices that can change their shape and/or function on-demand and over time.

A presentation by Antoine le Duigou is Associate-Professor in Institut de Recherche Dupuy de Lome at Université de Bretagne Sud (Lorient France).
This presentation proposes a critical overview of the current state of 4D printing of hygromorph biocomposites for stimuli-responsive applications.

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”
