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.

Topology optimization of structures with metamaterials – Presented by Jun Wu, TU Delft

Jun Wu

Jun Wu, TU Delft, will speak at 4D Printing & Meta Materials Conference, on April 17, during the 3D Printing Event in The Netherlands.

Lightweight structures are of ultimate importance in aerospace, automotive, and industrial design engineering. Typically structures are designed and manufactured with solid materials. Emerging porous metamaterials offer new opportunities and challenges for the design of functional structures.

4D-Printed Structures that React to Water, Developed by Harvard Researchers (Video)

4D-Printed Structures that React to Water, Developed by Harvard Researchers .A team of scientists at the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has evolved their microscale 3-D printing technology to the fourth dimension, time.

Inspired by natural structures like plants, which respond and change their form in response to environmental stimuli, the team has unveiled 4D-printed hydrogel composite structures that change shape when immersed in water.

3D, 4D printing technology to enable clothing & consumer products that will think for us (Video)

3D, 4D printing technology to enable clothing & consumer products that will think for us.Massachusetts Institute of Technology is widely considered the epicenter of the world’s technological innovation, and nothing is more on the forefront of the future than the MIT Media Lab. At events all over the world MIT’s Technology Review tries to start global conversations about technologies that matter, the people who make them and how they could change our lives. Throughout 2015 the chosen topics were as diverse as they were cutting edge, including Augmented Knowledge, Better Living Through Data, Infinite Energy, Rethinking Urban Infrastructure, and  Robots Among Us. At last week’s MIT’s Technology Review EmTech Brazil, audiences got a taste of what the future of wearable technology and self-assembling consumer products could be.

4D Technology May Allow Us to Replace Parts of the Body with the Same Material.Four-dimensional manufacturing has created what some argue is the latest wave in industrialisation. Dr Carlo Montemagno, Director of Ingenuity Lab, explains how nanotechnology 2.0 can revolutionise healthcare, manufacturing, and looking after the environment.

The New Economy: Four-dimensional manufacturing has created what some argue is the latest wave in industrialisation.

Here to share insight on how this technology has changed the marketplace, Dr Carlo Montemagno.   Continue reading “4D Technology May Allow Us to Replace Parts of the Body with the Same Material (Video)”

Students at TU Delft Use 4D Printing to Make Products with Origami-Like Characteristics that Change over Time

Students at TU Delft Use 4D Printing to Make Products with Origami-Like Characteristics that Change over Time.A relatively new development in 3D printing is the addition of a fourth dimension: time. Students at TU Delft used this fourth dimension to print a product with origami-like characteristics that changes over time. They did this by using a 3D printer to print a form on a fabric substrate that is held under tension. Along with eight other projects, including a 3D-printed bicycle frame made of rust-resistant steel and 3D models of heart defects that are used to aid doctor-patient consultations, this project is part of the ‘Advanced Prototyping’ exhibition on 27 October at TU Delft.

SLA Technology Used for Shaping Memory Polymers for the First Time (Video)

SLA Technology

SLA Technology Used for Shaping Memory Polymers for the First Time.While 3D printing is currently poised at the forefront of technology, 4D printing is nipping right at its heels. This next dimension in fabrication is really just 3D printing accentuated with the use of smart materials such as shape memory polymers (SMPs) that can be reformed into new shapes, and then counted on to revert back to their original shapes when an external stimulus, such as heat, is applied. (We’ve written a lot about 4D printing in the past, and you can find a quick, good overview here.) Continue reading “SLA Technology Used for Shaping Memory Polymers for the First Time (Video)”
