Researchers use architected auxetics to achieve 300 times more flexibility in new 3D printing design

There are young children celebrating the holidays this year with their families, thanks to the 3D-printed medical devices created in the lab of Georgia Tech researcher Scott Hollister. For more than 10 years, Hollister and his collaborators have developed lifesaving, patient-specific airway splints for babies with rare birth defects. These personalized Airway Support Devices are made of a biocompatible polyester called polycaprolactone (PCL), which has the advantage of being approved by the Food and Drug Administration. Researchers use selective laser sintering to heat the powdered polyester, which binds together as a solid structure. Devices made of PCL have a great safety record when implanted into patients. Unfortunately, PCL has the disadvantage of having relatively stiff and linear mechanical properties, which means this promising biomaterial has yet to be applied functionally to some other critical biomedical needs, such as soft tissue engineering. How do you make a firm thermoplastic into something flexible, and possibly capable of growing with the patient? Hollister's lab has figured out how.

“Barrera ends our conversation optimistically, remarking that she has no regrets over the events of the last few months, only immense gratitude, as she prepares for the release of her next film, Your Monster, a horror romance directed by Caroline Lindy. ‘I don’t regret anything. I’m very appreciative of all the support that I’ve gotten from my team, my friends, and my family. And from many people in the world who have shown me love and support. When I get stopped on the street now, it’s not because I’m recognised for being in a film; it’s mostly someone thanking me for speaking up for Palestine. It’s super weird, but it’s nice. It fills my heart. I’m just so, so grateful.’”

New biobased recyclable polyesters exhibit excellent tensile properties beyond polyethylene and polypropylene

The research group of Professor Kotohiro Nomura, Tokyo Metropolitan University, in cooperation with the research group of Director Hiroshi Hirano, Osaka Research Institute of Industrial Science and Technology, has developed biobased polyesters from inedible plant resources, which can be easily chemical recyclable and exhibit promising mechanical properties in films than commodity plastics. The work has been published in ACS Macro Letters. The development of high-performance, sustainable, recyclable plastics is important for the creation of a circular economy. Biobased polyesters made from plant resources are expected to become a promising alternative to commodity polymers such as polyethylene and polypropylene produced from petroleum. However, there have been few examples of the development of high-performance materials that exceed required mechanical properties such as tensile strength and elongation at break.

last week a woman perhaps in her 70s came up to me and asked why people wear jeans with holes in them (as you may guess: i was people). i first said that i liked these jeans mostly for the darker patches of denim—"no, I'm asking about the holes," said she. then i said that maybe people think it makes them look cool and tough and like they don't care. "but they clearly care!" she scoffed. i then said that i think the frayed edges of the holes add textural interest to an outfit where most of the fibers are regular and uniform, for example the fluff of the synthetic fleece jacket i was wearing. and this satisfied her. "I've never been able to ask anyone before" she said.

interestingly if she was 75 then she is about ten years younger than polyester (patented 1941) & ~30 years older than the reagan administration choices that made fast fashion economically viable. which are both factors in fraying being novel and cool and not an outstanding mending project. i assume
