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.

When the snapping shrimp—also known as the pistol shrimp—snaps its claw, it shoots out a jet of water fast enough to generate a bubble which, when it collapses, creates a loud noise and emits light. The high pressures and temperatures produced in this process lead to plasma formation.

It’s a fascinating competition that paints an incredibly detailed picture of what the future of Moon or even Mars exploration could look like one day — and we’ve never been closer to that future.

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.”



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.

(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.

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.

This 3D-printed concept wheel by tyre manufacturer Goodyear uses living moss to absorb moisture from the road, before converting it into oxygen through photosynthesis.

The Oxygene tyre was revealed at this year’s Geneva Motor Show that officially kicked off yesterday, 8 March 2018.

The concept is a response to research conducted by the World Health Organisation (WHO) that revealed more than 80 per cent of people who live in urban areas are exposed to air quality levels deemed to be unsafe.

Space architecture startup AI SpaceFactory achieved second place in the latest phase of a NASA-led competition, pitting several groups against each other in pursuit of designing a 3D-printed Mars habitat and physically demonstrating some of the technologies needed to build them.

With a focus on ease of scalable 3D-printing and inhabitants’ quality of life, as well as the use of modular imported goods like windows and airlocks, MARSHA lends itself impeccably well to SpaceX’s goal of developing a sustainable human presence on Mars as quickly, safely, and affordably as possible with the support of its Starship/Super Heavy launch vehicle.
