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.

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.
Ceramics are moving into the 4D printing realm for the first time
For some materials, researchers have already moved beyond 3D printing to what’s being called 4D printing. In this process, time becomes the fourth dimension and objects can transform themselves over time when influenced by elements such as heat, mechanical force, or a magnetic field.
Now, scientists in China have developed a novel ink that takes ceramics into this 4D printing realm for the first time, paving the way for new structural applications of the material—including for electronic devices and aerospace. Specifically, a team at City University of Hong Kong created a ceramic ink using a mixture of polymers and ceramic nanoparticles that can print ceramic precursors that are soft and can be stretched three times beyond their initial length.

Dirk J. Broer, Professor at Eindhoven University of Technology, will be presenting during the 4D Printing & Metamaterials Conference: “Morphing dynamics in light-triggered liquid crystal networks”. Continue reading “Dirk J. Broer, Eindhoven University of Technology presents at 4DMM Conference”
4D printing is unfolding as a technology that takes 3D printing to an entirely new level. Scientists at the University of Wollongong in Australia have created a hydrogel material that is compatible with a 3D printer that is able to change shape in response to water temperature.
