đź”— Doctors Modify Hot Glue Gun to Stick Broken Bones Back Together

via Futurism:

As detailed in a new paper published in the journal Device, the team came up with the unusual device to skip the need for prefabricating complex bone implants. In experiments involving rabbits, the researchers created 3D-printed grafts on the fly, allowing fractured bones to heal and regrow naturally.

Within 12 weeks following surgery on rabbits with severe femoral bone fractures, the researchers found no signs of infection — and better bone regeneration compared to control rabbits, which received more traditional bone cement grafts.

Conventional metal or donor bone implants have to be custom-fitted and manufactured ahead of time, making the new solution quite a bit more straightforward and therefore much faster.

3D printer + food waste + AI

in
The technology works through a combination of artificial intelligence and 3D printing. Users simply place their food waste into the machine, and the accompanying mobile app uses AI to analyze the materials through the phone’s camera. The system uses a self-trained object detection model to identify food types and assess their printability, then suggests appropriate “print recipes” based on the physical properties of your waste materials. The printer can create a wide variety of useful items from your kitchen scraps. Users can print cup holders, coasters, decorative items, and custom designs by simply dropping in food waste and selecting the desired form and size. The built-in material processing module helps users mix waste with natural additives to form a printable bioplastic paste, making the entire process seamless and accessible.

Things I've done the last few days:

  • Removed a dead lilac and replaced with a sweet almond.

  • Designed and printed a fucking adorable plant pot.

  • Drew a new comic that I was thinking about posting but might hold off and see how many I do and make it a zine.

  • Made a new metal piece; presently printing / prototyping plastic component.

  • Shed more skin as my latest tattoo continues to heal.

  • Fought hordes of C-virus infected in RESIDENT EVIL 6 which is a rather good time.

  • Bought a pressure washer and cleared off some of the house and yes ok fine i probably bought it to tide me over until POWERWASH SIMULATOR 2.

  • Removed big monitor from shed since I don't really need it anymore. Which I’ll probably need sooner rather than later since I just said I no longer need it.

3D printed T1D treatment?

To achieve that high density, Perrier and his colleagues 3D printed islets from a “bioink” made of human pancreatic tissue and alginate, a type of carbohydrate derived from seaweed. Live insulin-producing cells were mixed into this material.

“We put this bioink with the [human] islet into a syringe, and we print a special motif [with it],” says Perrier. This porous grid is designed to allow new blood vessels to grow around and through the structure.

In the lab, this technique “works very well”, says Perrier, noting that about 90 per cent of the islets’ cells survived and functioned for up to three weeks. “The next challenge is really to validate this finding in vivo.” Perrier and his colleagues presented their research at the European Society for Organ Transplantation (ESOT) 2025 meeting in London on 29 June.
