The status, barriers, challenges and future of 4D printing in design and engineering

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.

It concretely provides an additional temporal parameter to 3D printed objects and structures. The latter offers – via stimulus-responsive materials – promising transformation capabilities to objects whether at the functional, shape or property levels. By considering such abilities, researchers from chemistry, processes engineering, material science and mechanics of materials have investigated a large spectrum of stimulus-SMs associations with spectacular proof-of-concepts built from commercial 3D printers or custom ones.

Despite the abundant research initiatives, 4D printing requires to be shift across domains and scales in order to meet real and more robust system applications and then to be attractive for industry. The talk firstly reminds the fundamentals of SMs, processes, stimulus and AM to which an overview of significant research works related to 4D printing highlighting the current status as well as scientific, technical and organizational limitations is discussed. Built on this, a research roadmap for design and engineering supported by interdisciplinary research actions is proposed.


About Frédéric Demoly
Frédéric Demoly is Associate Professor at the ICB Institute from Univ. Bourgogne Franche-Comté (UBFC) / Belfort-Montbéliard University of Technology (UTBM) since 2011. Previously, he was involved as a Postdoctoral Researcher at Laboratory of Computer-Aided Design and Production (LICP) from Swiss Federal Institute of Technology (EPFL) in Lausanne (Switzerland).

His interests include design for assembly, additive manufacturing and 4D printing, knowledge formalization and representation, advanced computer-aided design, formal ontology, multi-material 3D printing and voxel-based modeling. He is involved as principal investigator in several collaborative research projects in the field of design for 4D printing.

About Jean-Claude André

Jean-Claude André is involved in light-matter interactions research. He is in 1984 at the origin of (probably) the first patent in 3D printing (i.e. stereo-lithography) and since this starting date involved in the fields of 3D and 4D printing. Current research concerns the development of new 3D Printing processes without going through the additivity step in 3D printing (with 3 patents on non-linear optic use for the 3D process), 4D printing (process, materials and software with, in particular, the Frederic Demoly’s teams as partners), the epistemology of bio-printing (with an exploration of the complexity associated with biological processes).
