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.

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.

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.
Auxetic Structures are a class of Metamaterials uniquely characterised by their Negative Poissons Ratio, that is when a lateral force is applied they expand longitudinally, becoming thicker and stronger, perpendicular to the strain.

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.
