MIT engineers use kirigami to make ultrastrong, lightweight structures
Produced with techniques borrowed from Japanese paper-cutting, the strong metal lattices are lighter than cork and have customizable mechanical properties.
Cellular solids are materials composed of many cells that have been packed together, such as a honeycomb. The shape of those cells largely determines the material’s mechanical properties, including its stiffness or strength. Bones, for instance, are filled with a natural material that enables them to be lightweight, but stiff and strong.
Inspired by bones and other cellular solids found in nature, humans have used the same concept to develop architected materials. By changing the geometry of the unit cells that make up these materials, researchers can customize the material’s mechanical, thermal, or acoustic properties. Architected materials are used in many applications, from shock-absorbing packing foam to heat-regulating radiators.
It's been way too long!
But no, I am not dead yet. And if I'm not dead yet, the projects don't stop. Please stay tuned for some brand new toys in the attic!
Worked on my velociraptor for the first time in a while, just a few more drafts to go I think. I might make a mount for it - heck if a mount is popular, I may make a mount for my other models too.

They hold together with only a few dots of glue instead of slots, which makes the models much easier to cut and assemble . #kirigami #origami #diy #papercraft #cutandfold #cardstock #paperart https://www.instagram.com/p/ConKBQluxBI/?igshid=NGJjMDIxMWI=
Stronger tape engineered through the ancient Japanese art of cutting paper, kirigami
Adhesive tape fulfills many purposes, from quickly fixing household appliances to ensuring a reliable seal on a mailed package. When using tape with a strong bond, removing it may only be possible by scraping and prying at the tape's corners, hoping desperately that surface pieces don't tear away with the tape.
But what if you could make adhesives both strong and easily removable? This seemingly paradoxical combination of properties could dramatically change applications in robotic grasping, wearables for health monitoring, and manufacturing for assembly and recycling.
Developing such adhesives may not by that far off through the latest research conducted by the team of Michael Bartlett, assistant professor in the Department of Mechanical Engineering at Virginia Tech, and published in Nature Materials on June 22.
The Japanese term for cut and folded paper art is kirigami. These 20 kirigami sculptures of horror scenes—the House of Usher, murder mansion, haunted house, Dr. Frankenstein’s laboratory, etc.—are very cool. And this book will instruct you on how to create them with instructions and templates for each. It was a gift, but the question remains: am I actually going to do this? It looks quite complicated to me. Although I have to say that the alien abduction scene and the kaiju attacking the city scene are pretty tempting. Maybe one day.
1 and 2 are the routine case where the horizontals (crease lines) are parallel to each other and result in a flat folding piece. In 1 the special case is that the centre point of the rectangle sits on the page crease and so the top and bottom bits show symmetry. In 2 the general case is that another crease is required placed horizontally such that AB=CD.
3 and 4 are the special and general cases where the creases that are horizontal in 1 and 2 are angled. In 3 the top and bottom are symmetrical about the mid-line crease. In four a crease line is constructed such that AB=CD and EF=GH, note that AE and DH need not be symmetrical.
Structures can be built across the oblique creases AE, BF, and DH but the verticals of these structure must be perpendicular to them, not the central crease, for flat folding.
If there were a Society for the Prevention of Cruelty to Copy Paper, they would really hate me since much has been sacrificed while trying to prove to myself that I understand these rules.
