3-D printed rocket engine made by NASA passes test with flying colors

Over the last three years, NASA engineers have been exploring using additive technology, like 3D printing, to manufacture key rocket engine parts. Tests on individual parts had worked well. Now, the space agency fitted all the parts onto a special test bench that behaves like a real rocket engine and fired it up for a test. The engine fired at 90,000 RPMs for 10 seconds to produce 22,000 pounds of thrust, with all performance test parameters showing ‘green’.

Amazing Custom Clock built using CNC, laser cutting and 3D printing – all using one hybrid printer

This beauty was designed, crafted and assembled by Matt Olczyk. The custom-made clock looks like a cross between old pendulum antiques and modern, minimalist designs. All the parts were custom made in Olczyk’s shop using CNC milling, laser cutting and 3D-printing. The real innovation, however, lied in the fat that all of these operations were performed by one single machine – the ZMorph Hybrid 3D printer.

With this in mind, Open Bionics, a startup working to provide affordable, 3D printed prosthetic hands for amputees has revealed prosthetic arms for kids inspired from Iron Man, Frozen or Star Wars. Based in Bristol, UK, Open Bionics first began its collaboration with Disney when

Check out the world’s first 3D electronics printer

I love disruptive technologies, and 3D printing is undoubtedly one of the leading such movements in the 21st century. This kind of tech will democratize manufacturing, moving it away from 3rd world sweatshops to your own garage. And no, you don’t have to be a geek to own one. Ten years from now, it should be as easy to use and as widespread in homes as a regular ink printer. But for now, 3D printing is limited, particularly as far as electronics are concerned. Usually, you have to print the plastic parts, then order electronic parts like circuits, chips or motors, before finally assembling it all together yourself. You can’t have a global manufacturing revolution if you need to be a lab wiz to print a new TV remote control to replace the one the dog just shred to pieces. But this is all changed. We’re just now seeing the first steps that might one day lead people to print their own smartphones.

Doctors transplant world’s first 3-D printed rib cage

Reconstructive surgery just got an upgrade after a patient who had lost four ribs and part of his sternum had a 3-D printed titanium replica fitted instead. This was the first such procedure. Although the operation was a sound success with the replica matching like a glove, doctors say that this sort of intervention is only for really extreme cases. You can’t become Wolverine overnight, not exactly at least.

University of California 3D printed fish are the most advanced microbots we built to date

Nanoengineers from the San Diego University of California used innovative, self-developed 3D printing methods to create multipurpose, fish-shaped microbots – that they call microfish – which can swim around efficiently through liquids, powered by hydrogen peroxide and are magnetically controlled.

This 3D-printed Stradivarius inspired violin sounds gorgeous

A French company called 3Dvarius partnered with musician Laurent Bernadac to see just how far they could stretch 3D printing capabilities. Why not, they thought, stretch the strings of a fully playable 3D-printed violin? Combing the leading craftsmanship of the past two centuries with the cutting edge tech of today, the engineers designed an electric violin based on the legendary Stradivarius.

Green 3D Printer Lets You Print With “Organic Ink”

We’ve written extensively about 3D printing and the doors it opens in terms of applications – from teeth to supercars – but this is something else: PrintGREEN is turning 3D printers into on-demand gardeners after designing a “green” 3D printer. The project comes from the University of Maribor in Slovenia, and the “ink” is essentially a mixture of soil, seeds, and water which

The world’s first 3D printer supercar looks stunning, has amazing specs and is eco-friendly

It can reach 100 km/h (60 mph) in 2 seconds, it has a 700 horsepower engine, it weighs 90% less than traditional cars, it has less emissions and it’s 3D printed – it may very well be the car of the future. Despite technological developments, the automobile industry has remained relatively stagnant in the past few decades. Sure, you have

Three dimensional printing goes metal: University of Twente researchers print copper and gold

The development of a method that would allow for metals to be used in 3D printing would open up a huge range of new possibilities, as the robustness and good thermal and electrical conductivity of metals lend well to a number of fields, such as microelectronics. A team from the University of Twente has developed a way to print 3D structures out of copper and gold, by using a pulsed laser to melt a thin film of metal and stacking the small droplets.

Scientists 3D print eggs, trick birds into thinking they’re real

It’s more than just a nasty trick – scientists have actually 3D printed eggs to help them better understand bird behaviour. They were especially interested in bird perception and what particular characteristics make them identify real eggs from fake ones.

Sea Turtle gets a new 3D-printed titanium jaw after being hit by a boat’s propeller

A turtle named Akut-3 was fitted with a new, custom made 3-D printed jaw by doctors at the Research, Rescue and Rehabilitation centre at Pamukkale University in Denizli, Turkey. The reptile was found badly injured at sea and brought to the center for rehabilitation. At first, the doctors healed the turtle’s wounds and hand fed her, but they knew they had to turn to something more drastic if the animal was to ever fend for herself in the wild again. They turned to a company in Turkey known for custom made prostheses, gave them a detailed CT scan of the turtle’s skull, then received a new beak made out of medical-grade titanium. The prosthesis perfectly fit Akut-3, who is aptly named like a cyborg.

NASA is offering over $2 million for the best design for a 3D printed Martian habitat

NASA is offering up to $2.25 million to anyone that can successfully design a habitat that can be 3D printed on Mars. The announcement is part of a broader attempt by NASA to outsource ideas and projects.

GE engineers 3D print mini jet engine, then power it to 33,000 RPMs

Printing your own mechanical parts or toys is really easy, not to mention fun, using a 3-D printer. But things get a bit trickier when you want to print the kind of parts that go into a car or airplane. Metal is a lot more complex to work with inside a 3D printer than polymers like ABS – the kind of film roles that get melted layer by layer to form a part of your liking once it cools down. Engineers at General Electric just demonstrated, however, that in practice it’s not that complicated to print parts out of metal alloys as it sounds. The team used additive technology to build a fully functional jet engine, then test powered it to 33,000 RPMs. The company is already using 3-D printed fuel nozzles in its next-generation aircraft engines, slated to role out in 2016.

After cancer ate out his face, this 74-year-old now uses a 3-D printed mask. Photos speak for themselves

Since 1990, Keith Londsdale went through no less than 45 different surgical procedures to remove basal cell carcinoma tumors, one of the most common skin cancers. The man survived the ordeal, but was left deformed as doctors had to remove his nose, upper jawbone and cheekbones. Basically, the 74-year-old-man now has a huge hole in his face.
