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.

Utilising Parametric Customisation to Translate Auxetic Structure Theory into Additively Manufactured Multimaterial Performative Geometries

Brittany Mark

presentation by Brittany Mark, Victoria University of Wellington at online 4D Printing & Meta Materials Conference, May 26, 2020, 09:00 – 12:00 CET.

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. This counterintuitive behaviour has many enhanced behavioural properties, our research has specifically focused on their response to impact forces for sports protection scenarios.

The effect of 4D printed internal structure on the shape memory effect of shape memory polymers

One way to 4D print is through the use of Shape Memory Polymers (SMP). these are a type of polymer which react to an external stimulus (e.g. temperature) and subsequently change their shape in a programmed manner. Previous 4D printing research has focused on different material properties (chemistry) or geometric shape (size, thickness etc.) to control its morphing behaviour.

4D Printing for Smart Cities – Duo presentation by Hiroya Tanaka & Hitomi Kuboki, Keio University SFC

Hiroya Tanaka

Hiroya Tanaka and Hitomi Kuboki from Keio University SFC will speak at the 4D Printing & Meta Materials Conference, on April 17, during the 3D Printing Event at Brightlands Chemelot Campus in The Netherlands.

We believe one of biggest application fields of 4D Printing is “Smart City”. We will introduce our novel design of “transformable car” and “environmental facade”, and explain updates of our original hardware (multi-head big 3d printer with super soft materials) and software (g-code editing).

4D Shoemaking – Presented by Niek van Sleeuwen, Perflex, Eindhoven University of Technology

4D Printing Conference

4D Shoemaking – Presented by Niek van Sleeuwen, Perflex, Eindhoven University of Technology at the 3rd edition of 4D Printing & Meta Materials Conference, which takes place on 18 April 2018 at Brightlands Chemelot Campus in Sittard-Geleen, The Netherlands.

The current way we deal with production of footwear is based on quick replacement of your current pair.
Huge pollution from unused half productions, consumerism and no development over time for you as an individual customer are just a few of the problems with the current way of producing. Continue reading “4D Shoemaking – Presented by Niek van Sleeuwen, Perflex, Eindhoven University of Technology”

FIFDM: 3D Printing with Continuous Fiber Reinforcement – Presented by Jens Schlimbach, The Institute for Composite Materials (IVW)

Program Jens Schlimbach

FIFDM: 3D Printing with Continuous Fiber Reinforcement – Presented by Jens Schlimbach, The Institute for Composite Materials (IVW), at the 3rd edition of 4D Printing & Meta Materials Conference, which takes place on 18 April 2018 at Brightlands Chemelot Campus in Sittard-Geleen, The Netherlands.

The presentation shows practical examples of research into the application of 3D printing technologies with continuous fiber reinforcement – the 4th dimension. The FIFDM process is a technology developed at the Institut für Verbundwerkstoffe at Technical University of Kaiserslautern, Germany. Research combines disciplines including design, material science and manufacturing know-how like robotics and 3D printing. The technology opens new possibilities like free placement or load-specific orientation of the fibers overcoming the limitation of in-plane layup. Methods and materials used will be discussed, along with future expectations and implications of smart materials and 3D printing within creative design potential.
