‘Molecular surgery’ reshapes living tissue with electricity but no incisions

Posted by in categories: 3D printing, biotech/medical

Traditional surgery to reshape a nose or ear entails cutting and suturing, sometimes followed by long recovery times and scars. But now, researchers have developed a “molecular surgery” process that uses tiny needles, electric current and 3D-printed molds to quickly reshape living tissue with no incisions, scarring or recovery time. The technique even shows promise as a way to fix immobile joints or as a noninvasive alternative to laser eye surgery.

The researchers will present their results today at the American Chemical Society (ACS) Spring 2019 National Meeting & Exposition.

“We envision this as a low-cost office procedure done under local anesthesia,” says Michael Hill, Ph.D., one of the project’s principal investigators, who will discuss the work at the meeting. “The whole process would take about five minutes.”

3D-printed shrimp claw makes plasma underwater

Posted by in category: 3D printing

To develop a new method of underwater plasma generation, scientists used 3D printing to replicate the shape of a snapping shrimp claw and the complex way it works.

As reported in Science Advances, the discovery could lead to significant improvements in the development of water sterilization, drilling, and more.

Supercomputer sheds light on how droplets merge

Posted by in categories: 3D printing, climatology, supercomputing

Scientists have revealed the precise molecular mechanisms that cause drops of liquid to combine, in a discovery that could have a range of applications.

Insights into how merge could help make 3D printing technologies more accurate and may help improve the forecasting of thunderstorms and other weather events, the study suggests.

A Real World ‘Star Trek’ Replicator Is Now Possible Thanks To New Breakthrough

Posted by in categories: 3D printing, energy, nanotechnology

A startup with alumni from MIT and Yale says it’s made a breakthrough in creating a next-generation material that should make it possible to 3D print literally anything out of thin air.

New York-based Mattershift has managed to create large-scale carbon nanotube (CNT) membranes that are able to combine and separate individual molecules.

“This technology gives us a level of control over the material world that we’ve never had before,” said Mattershift Founder and CEO Dr. Rob McGinnis in a release. “For example, right now we’re working to remove CO2 from the air and turn it into fuels. This has already been done using conventional technology, but it’s been too expensive to be practical. Using our tech, I think we’ll be able to produce carbon-zero gasoline, diesel, and jet fuels that are cheaper than fossil fuels.”

4D printing multi-metal products with a desktop electrochemical 3D printer

Posted by in categories: 3D printing, 4D printing, engineering

Four-dimensional (4D) printing can create complex 3D geometries that react to environmental stimuli, opening new design opportunities in materials science. A vast majority of 4D printing approaches use polymer materials, which limit the operational temperature during the process of engineering. In a recent study, Xiaolong Chen and co- workers at the Dyson School of Design and Engineering, Department of Earth Science and Engineering and Department of Materials at the Imperial College of London, U.K., developed a new multi-metal electrochemical 3D printer. The device was able to construct bimetallic geometries by selectively depositing different metals with temperature-responsive behavior programmed into the printed structure. In the study, they demonstrated a meniscus confined electrochemical 3D printing approach using a multi-print head design and nickel and copper materials as examples, the ability can be transferred to other deposition solutions. The results are now published in Scientific Reports.

5 Amazing Projects That Will Change the Future of Healthcare

Posted by in categories: 3D printing, bioprinting, biotech/medical, engineering

(3D-printed heart scaffold)

As the head of the University of Illinois Urbana-Champaign’s innovative Cancer Center, Bhargava has been plugging away at injecting more advanced engineering solutions into medical problems. The freeform 3D printer is one of the first futuristic achievements of that effort.

But Bhargava’s project is just one of a wave of technologies that stand to transform medicine and healthcare as we know it; to make them faster, more accurate, and hopefully, drastically more affordable. Microneedle patches, handheld diagnostic machines, and better sensing capabilities, as well as 3D bioprinting, are just a few of the technologies coming to a doctor’s office near you—or maybe even into your home—in the next decade.

Korea: Researchers 3D Printing Tracheas with Epithelial Cells & Chondrocytes

Posted by in categories: 3D printing, bioprinting, biotech/medical

Korean researchers have been experimenting further in the bioprinting of tracheal implants, publishing recent results in ‘Trachea with Autologous Epithelial Cells and Chondrocytes.’ The team of scientists details their use of polycaprolactone and hydrogel mixed with nasal epithelial and auricular cartilage cells.

After bioprinting an artificial trachea with these materials and tissue, they transplanted them into 15 rabbits, six of which were a control group. The goal was to find a way to overcome tracheal problems due to tumors, the most common of which are adenoid cystic carcinomas and squamous cell carcinomas. Previously there have been substantial challenges in creating viable tracheas that are anatomically correct and can produce a ciliated epithelium. Issues have arisen with infection, implants that become dislodged, have migrated, or experienced obstruction.
