Scientists can 3D-print a human cornea in ten minutes.

It was a good week for physics as a team with members from Australia and Switzerland invented a flux capacitor able to break time-reversal symmetry. They proposed a device based on quantum tunneling of magnetic flux around a capacitor. And another team with members from across the U.S. reported on a gravitational wave event that likely signaled the creation of a black hole—the merger of two neutron stars.

In biology news, a team of engineers led by Sinisa Vukelic invented a noninvasive technique to correct vision. Like LASIK, it uses lasers but is non-surgical and has few side-effects. And an international team of researchers found what they describe as the mother of all lizards in the Italian Alps, the oldest known lizard fossil, from approximately 240 million years ago. Also, a team at the University of Sydney found that walking faster could make you live longer. People do not even need to walk more, the team reported, they just need to pick up the pace of their normal stride to see an improvement in several health factors. And a team from Cal Poly Pomona discovered how microbes survive clean rooms and contaminate spacecraft—and it involved the cleaning agents themselves.

In other news, a team of researchers from the University of California and the University of Southern Queensland announced that they had identified 121 giant planets that may have habitable moons. And a team at Stanford University found that wars and clan structure might explain a strange biological event that occurred 7,000 years ago—male genetic diversity appeared to collapse for a time. Also, a team of researchers from MIT and Harvard University report the development of a 3D printer that can print data sets as physical objects—offering far more realistic, nearly true-color renderings.

That’s how long it will take to produce and launch a rocket if the parts are 3D printed, according to the CEO of Relativity Space, a startup that seeks to do just that.

The Dutch city of Eindhoven is to host the world’s first commercial housing project based on 3D-concrete printing, with the first of five planned houses due to start construction this year. The units were developed by a collaborative team including the Eindhoven University of Technology and will be purchased and let out by a real estate company upon completion.

The first house will be a single-floor, three-room house measuring 1000 square feet (95 square meters), to be followed by four multi-story units. The irregular shape of the buildings is based on “erratic blocks in the green landscape,” made possible due to the flexibility of form permitted by 3D-printing.

The human eye is a remarkably sophisticated organ and like the lens to a camera, it’s the cornea that focuses the flood of photons into a perceptible image. But for an estimated 15 million people around the world, eye disease and trauma make surgery the only path to clear vision.

In the next few years, artificial corneas may become more accessible thanks to new research out of Newcastle University in the United Kingdom. There, researchers mixed stem cells from the cornea of a healthy donor with collagen and algae molecules to create a bio-ink, which they 3D-printed into an artificial cornea. The research is currently just a proof-of-concept but lays the groundwork for future techniques to create low-cost, easy-to-produce bionic eyes.

There are almost limitless possibilities when it comes to 3D printing. Design your own color-changing jewelry? Fine. Fabricate your own drugs? No problem. Print an entire house in under 24 hours? Sure! Now, researchers have come up with a fast and easy way to print palm-sized models of individual human brains, presumably in a bid to advance scientific endeavours, but also because, well, that’s pretty neat.

In theory, creating a 3D printout of a human brain has been done before, using data from MRI and CT scans. But as MIT graduate Steven Keating found when he wanted to examine his own brain following his surgery to remove a baseball-sized tumour, it’s a slow, cumbersome process that doesn’t reveal any important areas of interest.

BARCELONA: In a bid to take the 3D printing industry to an entirely new level, global printing and PC major HP Inc has announced that its 3D metal printing solutions are set to enter the market later this year, thus giving the $12 trillion global manufacturing opportunity a new push.

HP, which entered the Additive Manufacturing (AM) field in 2016, currently has industrial-grade Multi Jet Fusion (MJF) 3D printing solutions that produce polymer (plastic)-based products.

“We will do an announcement on metal printing later this year and unveil to the world what kind of technology we will use. There are several metal technologies out there and we will share which we have zeroed in on to move forward and invest further,” Ramon Pastor, Vice President and General Manager of Multi Jet Fusion, HP, told IANS.

Sugar, that amazingly sweet treat some of us just can’t get enough of, has long been the fascination of children (and those with a child-like sweet tooth).

Its ability to be melted down into a glass-like substance enables confectionery artists to create tasty displays worthy of museums, or being served as a 3D printed dessert.

In fact, the same properties which make sugar so wonderful for cooking and designing also make it great for science.

When history’s pilgrims and pioneers arrived in a new territory, they used the land’s natural resources to build their settlements. Space colonists, on the other hand, will have to bring materials from Earth and assemble them on Mars. Andrew Rush, president and CEO of space-based manufacturing firm Made In Space, believes the process of creating off-world infrastructure will be similar to building IKEA furniture. Only the parts will be made with an advanced 3D printer and put together by an autonomous robot.

“We think the future of in-space operation is one of manufacturing and assembly, just like how you built the table you’re sitting on right now,” Rush says. “That table is a multi-material object, and its pieces were all manufactured in different ways. I don’t think space colonies are going to take a different approach.”
