Action-at-a-distance’ metamaterials for soft robotics, developed by TU Delft researchers
3D and 4D printing of edible and living hydrogel materials – Presented by Marc in het Panhuis, University of Wollongong
3D and 4D printing of edible and living hydrogel materials – Presented by Marc in het Panhuis, University of Wollongong, at the 4D Printing & Meta Materials Conference, on April 18, 2018, at Brightlands Chemelot Campus in Sittard-Geleen, The Netherlands.
Hydrogels are smart and multifunctional materials with a real potential for use novel applications including soft robotics, (edible) sensors and bionic implants. Consisting of a highly swollen polymer network, hydrogels are typically soft and brittle meaning they are not compatible with many traditional techniques used to process materials into structures.
In this presentation, I will demonstrate a variety of (extrusion-based) 3D and 4D printing techniques for processing hydrogel inks alongside other inks of structural polymers to create composite architectures including a smart valve, an artificial cartilage meniscus, an artificial tendon, brain-like structures, edible electronic circuits, stretchable devices and edible/living hydrogels.

4D Printing + Bioprinting = 4D Bioprinting
4D Printing + Bioprinting = 4D Bioprinting
Making and utilizing new materials to improve our life is a defining feature of mankind. We moved on from the stone age, to the bronze age, to the age of silicon and plastic. Now we are at the edge of a new episode, where technological breakthroughs allow us to create, investigate and dream of a total new range of structured forms of matter.

The Eiffel Tower recovering its shape using 4D Printing
The Eiffel Tower recovering its shape using 4D Printing.Unlike 3D printing, 4D printed structures have the potential to transform shape in a pre-programmed way in response to a stimulus (e.g. changes in temperature). These types of structural transformations currently exist outside of additive manufacturing, with research having already demonstrated “shape memory” and “smart material” properties.

TU Delft researchers develop self-twisting of DNA-inspired constructs (VIDEO)
TU Delft researchers develop self-twisting of DNA-inspired constructs. Researchers at TU Delft have made flat surfaces that are 3D printed and then ‘taught’ how to self- fold later. The materials are potentially very well suited for all kinds of medical implants. They report on their findings in the October 24th edition of Materials Horizons which features this research on its cover.

Researchers develop 3D printed metamaterial that shrinks when heated
Researchers develop 3D printed metamaterial that shrinks when heated. Members of Lawrence Livermore National Laboratory’s Additive Manufacturing Initiative are among a group of researchers who have developed 3D printed materials with a unique property — instead of expanding when heated, they shrink. Continue reading “Researchers develop 3D printed metamaterial that shrinks when heated”
New 3D-printed material technology lets objects be both hard and soft (Video)
New 3D-printed material technology lets objects be both hard and soft. Recently, researchers started to engineer not only the outer shape of objects, but also their internal microstructure. Such objects, typically based on 3D cell grids, are also known as metamaterials. Metamaterials are artificial structures with mechanical properties that are defined by their usually repetitive cell patterns, rather than the material they are made of.

New shape-changing smart material developed by Washington State University researchers (Video)
Washington State University researchers have developed a unique, multifunctional smart material that can change shape from heat or light and assemble and disassemble itself. They have filed a provisional patent on the work.
This is the first time researchers have been able to combine several smart abilities, including shape memory behavior, light-activated movement and self-healing behavior, into one material. They have published their work in ACS Applied Materials & Interfaces. Continue reading “New shape-changing smart material developed by Washington State University researchers (Video)”
