Scientists have developed an innovative 3D bioprinter capable of generating replacement tissue that’s strong enough to withstand transplantation. To show its power, the scientists printed a jaw bone, muscle, and cartilage structures, as well as a stunningly accurate human ear.
It sounds like something straight out of a comic book, but after losing his sternum and part of his rib cage to cancer, a 54-year-old Spanish man received the world’s first 3D-printed chest prosthetic made from lightweight, but incredibly strong, titanium.
Speaking as someone who has recently recovered from a broken rib, I’m jealous. I was told that doctors can reinforce a break with titanium, but that the surgery is a bigger deal so it’s only done if absolutely necessary. Once the break is stabilized, the healing process can actually begin. Which speaking from experience, means a lot less pain. But the titanium used for a break needs to be taken out before ~2 years, or it fuses with the bone.
The article talks about how the replacement was made, but no mention about how long term this is meant to be.
It’s not just electronics and other product manufacturing that 3D printers promise to revolutionize. The machines might one day replace all the appliances in your kitchen when it comes to making dinner, or more importantly, making candy.
3D printing food is a step closer to Star Trek’s replicator! I haven’t been that impressed with the other things 3D printing has made possible due to size/material constraints, so this is refreshing news for me.
YouTuber Russell Munro used a 3D printer to construct the transforming base for this cake. All of the baked and frosted parts then help to cover up the motors and other mechanisms that allow this wonderful creation to transform.
You can get a better look at the skeleton in this video:
On June 15, a team of researchers at UNIST has announced that they have developed a high-resolution 3D printing technology that is capable of printing electronic circuits on plastic, metallic or magnetic nanoparticles that are curved and much flexible. According to the team, led by Prof. Jang-Ung Park (School of Materials Science and Engineering), they have succeeded in imprinting ultra-fine 3D patterns that are as small as 0.001 mm in size. This is thinner than a red blood cell.
The article talks about wearable electronics, but I wonder if something like skin would be possible. Rather than grafting…
Sure, cost is upwards of $50,000. But that’s now – eventually the cost will come down. The size of the unit isn’t mentioned, as shipping one to the space station (or other remote places) might make some things more accessible.
By relying on specific DNA:DNA interactions as a “smart glue”, we have assembled microparticles into a colloidal gel that can hold its shape. This gel can be extruded with a 3D printer to generate centimeter size objects. We show four aspects of this material: The colloidal gel material holds its shape after extrusion. The connectivity among the particles is controlled by the binding behavior between the surface DNA and this mediates some control over the microscale structure. The use of DNA-coated microparticles dramatically reduces the cost of DNA-mediated assembly relative to conventional DNA nanotechnologies and makes this material accessible for macroscale applications. This material can be assembled under biofriendly conditions and can host growing cells within its matrix. The DNA-based control over organization should provide a new means of engineering bioprinted tissues.
The researchers have developed a series of nanoparticles made of either polystyrene or polyacrylamide that are then coated with DNA. Yes, packing peanuts… Don’t start hoarding just yet – it’s pretty basic, but they’re working on more complex structures. That could mean organs, medications, Star Trek replicators…
Aboard the ISS, astronauts are sipping their espresso through straws attached to plastic pouches, the vessels developed through a collaboration between an Italian engineering team and the coffee company Lavazza. As any snob worth their weight in beans obviously knows, a plastic pouch and a straw are NOT ideal methods for enjoying espresso. Part of what makes a great (tiny) cup is the crema that forms on the top—caused by the emulsified oils that rise to the top thanks to gravity, creating that silky light brown layer of foamy stuff above the espresso itself.
Taking inspiration from the microscopic rounded structures that creatures like starfish naturally grow to improve their limited vision, researchers at the University of Michigan have succeeded in artificially creating smooth facet-less crystals in the lab that have the potential to revolutionize everything from solar panels to LEDs.
The article touches on pills & medication at the end – the start suggests that LEDs and solar cells stand to benefit too. I have to wonder what the pharmacology industry would have to say about it. We only have to look at the news about 3D printed firearms to get an idea of lies ahead. But it would be helpful for those in remote areas who need medication, assuming resources are available.
