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.
3D printing is a dumpster fire of stupid, obvious patents, but thankfully many of these are expiring; this year, the stupid patent on putting sides on a 3D printer (extrusion printers are very sensitive to errant breezes and just a puff of wind can ruin a print that took hours, just minutes before it completes).
I've been semi-seriously joking about "AK-3DPs" (3D printed assault rifles) for years, and while the attempts to limit the spread of 3D printed guns have been sloppy and poorly formulated (as have the Trump admin's attempt to roll them back) the state of the art is still progressing.
It’s historically been tough and slow-going to 3D print objects made from multiple materials. Now, Harvard researchers developed an ingenious nozzle that enables the 3D printer to spew out eight different materials at the resolution of a human hair. To demonstrate the system, they printed fantastic flexible origami structures and even a “soft” robotic millipede […]
When the SNES launched back in the early 1990s, it changed gaming forever. One of the innovations was a gamepad with four action buttons — something that has remained a constant on controllers ever since. The 8BitDo SN30 Bluetooth Gamepad brings that iconic design up to date, with Bluetooth connectivity and support for multiple platforms. […]
After a long day at work, cooking a meal from scratch can seem like too much trouble. Unfortunately, the alternative is usually something unhealthy. Enter the Mellow Sous Vide Precision Cooker. This compact water bath uses cutting-edge technology to cook meat and veggies at the perfect temperature for exactly the right amount of time. It […]
In the course of any day, we encounter many different audio environments. If you are wearing earbuds, the ambient noise level can affect your listening experience. The HUB wireless earbuds adapt to different surroundings using smart noise-cancellation technology. They can either block out distractions or enhance conversations. They are normally priced at $250, but you […]
