The first 3D-printed human corneas

Posted on Updated on

As reported by Experimental Eye Research, ” how stem cells (human corneal stromal cells) from a healthy donor cornea were mixed together with alginate and collagen to create a solution that could be printed, a ‘bio-ink’.

Using a simple low-cost 3D bio-printer, the bio-ink was successfully extruded in concentric circles to form the shape of a human cornea. It took less than 10 minutes to print.”

On the authority of Che Connon, Professor of Tissue Engineering at Newcastle University, who led the work, “Many teams across the world have been chasing the ideal bio-ink to make this process feasible.
Our unique gel – a combination of alginate and collagen – keeps the stem cells alive whilst producing a material which is stiff enough to hold its shape but soft enough to be squeezed out the nozzle of a 3D printer.
This builds upon our previous work in which we kept cells alive for weeks at room temperature within a similar hydrogel. Now we have a ready to use bio-ink containing stem cells allowing users to start printing tissues without having to worry about growing the cells separately.”

4D printed materials that transform underwater

Posted on Updated on

As said by Tibbits,” Possibilities from 4D printed materials that transform underwater, or fibers that snap into a particular shape. We want to think about what’s coming next and see if we can really lead that worked with Steelcase to develop a process for 3D printing plastic into the liquid for furniture parts, called rapid liquid printing. This process prints within a gel bath to provide support for the printed parts and minimize the effect of gravity. With this printing technique, they can print centimeter- to meter-scale parts in minutes to hours with a range of high-quality industrial materials like silicone rubber, polyurethane, and acrylics.”

3-D print colloidal crystals

Posted on Updated on

 

According to Mechanosynthesis Group, MIT, “Highlights from our publication on direct-write colloidal assembly, a new fabrication process combining principles of self-assembly with 3D printing.3-D print colloidal crystals.”
According to study co-author Alvin Tan, a graduate student in MIT’s Department of Materials Science and Engineering, “If you blew up each particle to the size of a soccer ball, it would be like stacking a whole lot of soccer balls to make something as tall as a skyscraper. That’s what we’re doing at the nanoscale.
If you could 3-D print a circuit that manipulates photons instead of electrons, that could pave the way for future applications in light-based computing, that manipulate light instead of electricity so that devices can be faster and more energy efficient.
According to graduate student Justin Beroz, assistant professor of mechanical engineering Mathias Kolle, and an associate professor of mechanical engineering A. John Hart. For the first time, we’ve shown that it’s possible to build macroscale self-assembled colloidal materials, and we expect this technique can build any 3-D shape, and be applied to an incredible variety of materials. Mr.Hart, the senior author of the paper.”

Ohio officials seek to promote 3D-printing of prosthetics via law change.

According to Lt. Gov. Jon Husted, during a Statehouse news conference on Thursday, “Aaron is providing an innovative and creative solution to a problem that he and many other people face, and I don’t want outdated laws to stand in his or anyone else’s way.”
According to some comments from the video,”

I have a robotics class in my high school, and the entire class has to build some with the tools they learned from previous years. I am the only one that is making a fully functional 3D printed arm.

3D printing helps reconstruct jaws

Posted on Updated on

According to the American National Cancer Institute, and Dr. Nguyễn Anh Khôi, deputy head of surgery department No.5 at the hospital, “Tobacco use, heavy alcohol use, and human papillomavirus increase the risk of these cancers.
Doctors decided to perform surgery to remove his lower jaw and reconstruct it using the 3D printing technology”.

3D printed 5G antenna

Posted on Updated on

According to Mark Mirotznik, professor of electrical engineering at the University of Delaware,” for technologies like wearables and things like that, it means we don’t have to have flat electronics anymore or flat antennas, it can be flexible. So for those applications, it’s really novel that you can actually print all of this stuff on a flexible membrane. It opens up new possibilities. 3D printing (specifically, NanoParticle Jetting technology offered by XJet) is the only manufacturing technique capable of meeting the production demands of a new kind of passive beam steering 5G antenna designed by his team.”

Ocean waste to create 3D-printed seashell sculptures. According to Rotterdam-based research and design studio, ‘the new raw’ has conceived a pioneering project which transforms ocean waste into digitally crafted sculptures. the initiative, which repurposes abandoned fishing nets and processes them into threadlike filaments to create design objects, raises awareness of the environmental issues of marine plastic pollution”.

3D Printing News Alert(New space for a 3D printing company in the Houston)

Posted on Updated on

According to 3D printing company re 3D’s co-founder, Matthew Fiedler, “You now have access to large-scale 3D printers. The Houston company opened its community space in its factory located next to the NASA Johnson Space Center in southeast Houston.

The company makes an affordable and customizable 3D printer, called the Gigabot, and has clients across industries in over 50 countries.
A hidden scientific gem resides at Southwestern Adventist University: more than 20,000 dinosaur bones and precious prehistoric data. In the university’s Dinosaur Museum and Research Center, a Gigabot is being used to 3D print bones.
Greneker is a leader in the world of custom mannequin design and manufacturing, and they’re staying competitive in the fast-moving apparel marketplace with the help of 3D printing. Their Los Angeles office has a dedicated 3D printer room which is home to four Gigabots”.
