Researchers have spent decades exploring methods to 3D print organs for transplant but progress is slow due to the complex structure of, say, a kidney or pancreas. Precise Bio, a startup founded by scientists from Wake Forest Institute for Regenerative Medicine, claim that the first real success will come from 3D-printed corneas. They've already conducted animal studies and are building a roadmap toward human trials. From IEEE Spectrum
Corneas could be the first mainstream application of bioprinting, (Precise Bio CEO Aryeh) Batt says, in part because they have a layered structure that’s a good match for the technology. Each layer consists of different types of cells and fibers, which the printer could lay down in sequence, and these layers don’t contain blood vessels or nerves. What’s more, putting a new kind of transplant in the eye is inherently safer than implanting one deep in the body, since physicians could easily check for signs of trouble and could remove the tissue if anything seemed wrong.
There’s certainly a need for more corneas in the world, says Kevin Corcoran, president and CEO of the Eye Bank Association of America. In 2017, his members supplied nearly 51,000 transplantable corneas to patients in the United States, and also sent more than 26,000 abroad. Internationally, “there is a tremendous amount of unmet demand,” he says. “It’s estimated that 10 million people suffer from corneal blindness globally, primarily because they lack access to effective and affordable treatment.”
Part of Precise Bio’s proprietary approach is its printer, which uses a technique called laser-induced forward transfer to propel droplets of bioinks onto a surface. Just as a desktop printer has cartridges containing different colors of inks, the Precise Bio printer has cartridges containing different biological materials such as epithelial cells and collagen.
Experimental fashion designer Anouk Wipprecht—most famous for her Robotic Spider Dress from a few years ago—has now created the Proximity Dress to help with physical distancing during the pandemic. The 3D-printed electromechanical dress poofs out when triggered by proximity and thermal sensors detecting someone getting too close to the wearer. From 3D Printing Media Network: […]
“The glove remover is a simple device that reduces the risk of contamination when changing protective gloves while increasing efficiency and convenience.” The website has a link to the 3D model so you can print your own (if you have a 3D printer or access to one).
In this video, the crazed maker Matt Denton (who someone in the comments refers to as the Colin Furze of giant 3D printed LEGO) 3D-prints a human-sized LEGO go-kart. My latest 3D Printed project is this GIANT LEGO Go-Kart large enough for me to ride! Yes, I’m hoping this time that this version will be […]
Back in the 50s and 60s, it was no big deal in most areas to make a call to your local liquor store and have beer, wine and spirits delivered right to your house with little to no restriction. However, that ease and simplicity certainly isn’t in place today. Alcohol delivery laws in 2020 are […]
Unless you’re a regular cannabis user, you might be surprised to learn that the plant itself is basically just that — a plant. It’s not until you put cannabis under high heat that the process of decarboxylation breaks down that raw form into the psychoactive compounds that can actually benefit the body. This unlocking process […]
With our smartphones serving as the vital tether that links us to the rest of our lives, it’s no wonder how low batteries and power emergencies can occasionally feel like a life-and-death situation. I mean, it’s usually not, of course…but darned if it doesn’t feel that way when your indicator is showing only 5 percent […]
