The first edition of the 4D Printing & Meta Materials conference was held in 2015. Since then many editions took place. Speakers from all over the world presented at our conferences and shared their knowledge. To get an overview of these editions please go to this page.

The majoity of speakers are coming from universities, but a growing number of companies are looking into applications of 4D Printing and / or Meta Materials. Also participants of the conference came mainly from Universities, but the trend is chaning.

4D printing of composites.

composites

A presentation by professor Suong Hoa, Director, Concordia Center for Composites (CONCOM), Canada.

4D printing of composites (abbreviated as 4DPC) is a manufacturing technique that can produce composite structures with complex geometries without the need for complex molds. The technique is also termed “Mouldless composite manufacturing”. This technique utilizes light weight, high strength, high stiffness composite materials that have been used to make light weight components for space structures, aircrafts, automobiles. wind turbine blades, and sports equipment.

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

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.

Enabling hierarchical motion in 4D printed structures by means of the temperature-memory effect in polymers: experimental and computational aspects

structures

A presentation by Giulia Scalet, Assistant Professor, DICAr, University of Pavia.

4D printing is a disruptive additive manufacturing paradigm that utilises active materials to produce customized structures capable of changing their shape, properties, and functionalities over time (the 4th dimension) under the application of proper stimuli.

4D printing of bioinspired hygromorph natural fibre composite : Green and Smart functionalities

shap

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.

4D printing or not 4D printing? Mechanically actuatable 3D scaffolds for regenerative medicine

Lorenzo Moroni

by Lorenzo Moroni, MERLN, Maastricht University

A key factor in scaffold-based tissue and organ regeneration relies on enhancing (stem) cell-material interactions to obtain the same original functionality. A possible way to build in functionality at the interface between materials and cells can be offered by 4D (bio)printing. Whether we are really witnessing 4D printing, a process which should be defined when the programmed temporal shape change happens during the 3D manufacturing itself, or not is still to be clarified in the field.
