In Brief.

• New 3D printed bones are ‘hyperelastic,’ making them more malleable during procedures.
• 3D printers in hospitals could provide the hyperelastic bone ink, so surgeons could make implants in 24 hours.

Remarkable.

This best describes the new bone-mending technology developed at Northwestern University in Evanston, Illinois by Ramille Shah and her colleagues. They used ink made from a natural bone mineral called hydroxyapatite, mixed with PLGA, a mineral-binding polymer that makes the implants elastic.

Spectators of the DARPA Robotics Challenge finals in 2015 would have noticed that many of the competing robots were padded up for protection in case they took a tumble. MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) is looking to build customizable shock-absorbing protection into robots by using 3D printing to produce soft materials that not only dampen the impact of falls, but also allows them to carry out safer, more precise movements.

Robotics engineers have long had a keen interest in soft materials. At their simplest, such materials can protect robots against falls and collisions, but can also protect people in environments were robots and humans are increasingly working together. Going beyond this, soft materials also allow for making completely soft robots that can mimic animal design.

Nice POV read.

We know that emerging innovations within cutting-edge science and technology (S&T) areas carry the potential to revolutionize governmental structures, economies, and life as we know it. Yet, others have argued that such technologies could yield doomsday scenarios and that military applications of such technologies have even greater potential than nuclear weapons to radically change the balance of power. These S&T areas include robotics and autonomous unmanned system; artificial intelligence; biotechnology, including synthetic and systems biology; the cognitive neurosciences; nanotechnology, including stealth meta-materials; additive manufacturing (aka 3D printing); and the intersection of each with information and computing technologies, i.e., cyber-everything. These concepts and the underlying strategic importance were articulated at the multi-national level in NATO’s May 2010 New Strategic Concept paper: “Less predictable is the possibility that research breakthroughs will transform the technological battlefield … The most destructive periods of history tend to be those when the means of aggression have gained the upper hand in the art of waging war.”

As new and unpredicted technologies are emerging at a seemingly unprecedented pace globally, communication of those new discoveries is occurring faster than ever, meaning that the unique ownership of a new technology is no longer a sufficient position, if not impossible. They’re becoming cheaper and more readily available. In today’s world, recognition of the potential applications of a technology and a sense of purpose in exploiting it are far more important than simply having access to it.

Scientists at the US Oak Ridge National Laboratory are assembling the world’s first 3D-printed hydraulic excavator, a prototype which they say will explore the feasibility of printing with metal alloys.

3D-printing, or additive manufacturing (AM), mostly uses plastics of some sort to create objects layer by layer. Plastics are cheap, light, and easy to melt, lending themselves to the process. Metals, on the other hand, are heavy, costly, and melt at much higher temperatures – making them a challenging material for 3D printing.

But metals are what is needed if truly useful machines like cars or tractors are to be 3D-printed.

A Northwestern Engineering research team has developed a 3D printable ink that produces a synthetic bone implant that rapidly induces bone regeneration and growth. This hyperelastic “bone” material, whose shape can be easily customized, one day could be especially useful for the treatment of bone defects in children.

Bone implantation surgery is never an easy process, but it is particularly painful and complicated for children. With both adults and children, often times bone is harvested from elsewhere in the body to replace the missing bone, which can lead to other complications and pain. Metallic implants are sometimes used, but this is not a permanent fix for growing children.

“Adults have more options when it comes to implants,” said Ramille N. Shah, who led the research. “Pediatric patients do not. If you give them a permanent implant, you have to do more surgeries in the future as they grow. They might face years of difficulty.”

A 3D-printing company is aiding NASA by using its additive manufacturing technology to create an accurate replica of a meteorite located 34 million miles from Earth.

Measuring approximately 2 feet in length, the meteorite known as Block Island was first discovered on Mars by the Exploration Rover Opportunity in 2009. Studying it is an important part of furthering our knowledge about Mars and other planets, but at present the prospect of bringing it to Earth to examine u close is out of the question.

Fortunately, the Mars rover was able to take images and measurements to transmit back home, and this data has now been used by Mcor Technologies, an Ireland-based 3D-printing company, to create a life-size Block Island model.

Tiny sensors made through nanoscale 3D printing may be the basis for the next generation of atomic force microscopes. These nanosensors can enhance the microscopes’ sensitivity and detection speed by miniaturizing their detection component up to 100 times. The sensors were used in a real-world application for the first time at EPFL, and the results are published in Nature Communications.

Just like checking your bag on a commercial airline, space travel comes with some pretty big weight restrictions. How big? According to estimates, reaching space costs a whopping $10,000 per pound, which means that every ounce saved has a big impact on the bottom line.

That’s where a group of Danish researchers comes in. The team is working on a synthetic biology project called CosmoCrops, which hopes to use bacteria to make it possible to 3D print everything needed for a respectable space mission, using a cutting-edge co-culturing system. And it could even make life better for those of us back on Earth in the process.

“We are trying to make space exploration cheaper, because many inventions we use in our daily life were invented because of space exploration, like Velcro and solar energy,” Joachim Larsen, one of the students working on the project, told Digital Trends. “The way we want to achieve this is to [be] able to produce everything from food to medicine and bioplastic for 3D printers out in space — making the space rocket a lot lighter.”

A 3D printed house, does it really exist? Here are the most fascinating 3D printed houses in the world, from tiny town cabins to an entire village.

“What’s wrong with brick and mortar, glass and concrete?”, you might ask. “Why to build a 3D printed house?” Apart from the obvious answer – because we can -, there are various good reasons for using 3D printing methods in constructing buildings:
