3D-Printed Rocket Engine Part Passes Key NASA Test by Miriam Kramer, SPACE.com Staff Writer

A 3D-printed rocket engine injector has passed a major NASA test, potentially heralding a new age of propulsion-system manufacturing, space agency officials say.

NASA and Florida-based company Aerojet Rocketdyne put the injector — which was built using 3D printing (also called "additive manufacturing") technology — through a series of hot-fire trials, agency officials announced last week.

"Hot-fire-testing the injector as part of a rocket engine is a significant accomplishment in maturing additive manufacturing for use in rocket engines," Carol Tolbert, manager of the Manufacturing Innovation Project at NASA's Glenn Research Center in Cleveland, Ohio, where the tests were conducted, said in a statement.

"These successful tests let us know that we are ready to move on to demonstrate the feasibility of developing full-size, additively manufactured parts," Tolbert added.



Aerojet Rocketdyne crafted the engine injector using high-powered lasers that liquefied and fused metallic powders into the proper structure.

Rocket engine injectors typically take a year or more to build. Employing 3D printing technology can reduce this to less than four months while also cutting costs by 70 percent, NASA officials said.

"NASA recognizes that on Earth and potentially in space, additive manufacturing can be game-changing for new mission opportunities, significantly reducing production time and cost by 'printing' tools, engine parts or even entire spacecraft," Michael Gazarik, NASA's associate administrator for space technology in Washington, D.C., said in a statement.

"3D manufacturing offers opportunities to optimize the fit, form and delivery systems of materials that will enable our space missions while directly benefiting American businesses here on Earth," he added.


NASA's interest in 3D printing appears to be strong and growing. For example, the space agency is partnering with California company Made in Space to send a 3D printer to the International Space Station next year.

And NASA recently funded the development of a prototype "3D pizza printer" that could help feed astronauts on long space journeys, such as the 500-day trek to Mars.

3D printing has been used to craft certain rocket parts before, but usually this form of manufacturing is employed to build less critical components of the complex machines, Aerojet Rocketdyne additive manufacturing program manager Jeff Haynes said.

"The injector is the heart of a rocket engine and represents a large portion of the resulting cost of these systems," Haynes said in a statement. "Today, we have the results of a fully additive manufactured rocket injector with a demonstration in a relevant environment."

Foodini is a 3D printer for everything from burgers to gnocchi

Who wants a 3D printer for just candy when you can have one that prints a five-course dinner instead? That's the idea behind Foodini, a new 3D printer that takes fresh ingredients and turns them into a culinary masterpiece. The device can do things like make custom ravioli, your own unique crackers or cookies, or even an intricate dark chocolate vase (if you just have to print candy). Its creations are made by filling the printer's "food capsules" with fresh ingredients and then inputting a recipe for the device to create. Foods can be printed in just a few minutes and eaten right away (if they're made from pre-cooked materials) or cooked after printing. Foodini is currently seeking funding on Kickstarter to manufacturer its first run of the printers. $1,000 gets you in line to get one in January 2015, and a $2,000 investment can have you throwing your first printed dinner party by October of this year.

Scientists try 3-D printer to build human heart

Post by Munchy »

LOUISVILLE, Ky. (AP) — It may sound far-fetched, but scientists are attempting to build a human heart with a 3-D printer.

Ultimately, the goal is to create a new heart for a patient with their own cells that could be transplanted. It is an ambitious project to first, make a heart and then get it to work in a patient, and it could be years — perhaps decades — before a 3-D printed heart would ever be put in a person.

The technology, though, is not all that futuristic: Researchers have already used 3-D printers to make splints, valves and even a human ear.

So far, the University of Louisville team has printed human heart valves and small veins with cells, and they can construct some other parts with other methods, said Stuart Williams, a cell biologist leading the project. They have also successfully tested the tiny blood vessels in mice and other small animals, he said.

Williams believes they can print parts and assemble an entire heart in three to five years.

The finished product would be called the "bioficial heart" — a blend of natural and artificial.

The biggest challenge is to get the cells to work together as they do in a normal heart, said Williams, who heads the project at the Cardiovascular Innovation Institute, a partnership between the university and Jewish Hospital in Louisville.

An organ built from a patient's cells could solve the rejection problem some patients have with donor organs or an artificial heart, and it could eliminate the need for anti-rejection drugs, Williams said.

If everything goes according to plan, Williams said the heart might be tested in humans in less than a decade. The first patients would most likely be those with failing hearts who are not candidates for artificial hearts, including children whose chests are too small to for an artificial heart.

Hospitals in Louisville have a history of artificial heart achievements. The second successful U.S. surgery of an artificial heart, the Jarvik 7, was implanted in Louisville in the mid-1980s. Doctors from the University of Louisville implanted the first self-contained artificial heart, the AbioCor, in 2001. That patient, Robert L. Tools, lived for 151 days with the titanium and plastic pump.

Williams said the heart he envisions would be built from cells taken from the patient's fat.

But plenty of difficulties remain, including understanding how to keep manufactured tissue alive after it is printed.

"With complex organs such as the kidney and heart, a major challenge is being able to provide the structure with enough oxygen to survive until it can integrate with the body," said Dr. Anthony Atala, whose team at Wake Forest University is using 3-D printers to attempt to make a human kidney.

The 3-D printing approach is not the only strategy researchers are investigating to build a heart out of a patient's own cells. Elsewhere, scientists are exploring the idea of putting the cells into a mold. In experiments, scientists have made rodent hearts that beat in the laboratory. Some simple body parts made using this method have already been implanted in people, including bladders and windpipes.

The 3-D printer works in much the same way an inkjet printer does, with a needle that squirts material in a predetermined pattern.

The cells would be purified in a machine, and then printing would begin in sections, using a computer model to build the heart layer by layer. Williams' printer uses a mixture of a gel and living cells to gradually build the shape. Eventually, the cells would grow together to form the tissue.

The technology has already helped in other areas of medicine, including creating sure-fitting prosthetics and a splint that was printed to keep a sick child's airway open. Doctors at Cornell University used a 3-D printer last year to create an ear with living cells.

"We're experiencing an exponential explosion with the technology," said Michael Golway, president of Louisville-based Advanced Solutions Inc., which built a printer being used by Williams' team.

How 3D printing will radically change the world

If you're not excited by 3D printing it's because you're not thinking big enough, say some technology visionaries who predict that life on Earth will soon radically change because of it.

According to these futurists, 3D printing will make life as we know it today barely recognizable in 50 to 75 years.

"Realistically, we're going to be living to 100 ...110. With bio-printed organs, living to 110 won't be anything like living to that age today," contends Jack Uldrich, a technology trend expert. "We're already printing skin, kidneys, a replica of a beating human heart. If a person loses a limb, we'll be able to print, layer by layer, a replacement. It's theoretically possible."

Uldrich says companies will soon be able to manufacture goods domestically, with virtually no wasted materials and no need for international outsourcing.

"If we can print a shoe here, we don't have to go to China or Indonesia," he says. Uldrich also predicts the demise of the construction and agriculture industries, which he says will make many traditional methods of building and food production obsolete.

"Right now, you have to feed a cow 20,000 gallons of water and 10,000 pounds of grain in its lifetime. Then there's the cost of slaughtering, shipping and packaging. Our grandkids will say, 'that was insane.' "

In fact, 3D printing technology is advancing at a staggering rate. American designers are now working on 3D printed cars, while in China and Holland, 3D printers are building entire houses. The first 3D printed hamburger was recently created in England, heralding the possibility of a man-made food supply.

Boeing, GE and other industry leaders are manufacturing state-of-the-art aerospace equipment with the new technology, while NASA, using Zero-G technology, is demonstrating how 3D printers will one day be used in space.

Perhaps most dramatic are the advances being made in the medical field. Research and development of 3D printing-based medical techniques have already saved countless lives and opened the doors to previously unimaginable possibilities in medicine.

"It's opening up a whole new world," agrees Sarah Boisvert, chief 3D printing officer at Potomac Photonics and a technology consultant at MIT. However, she cautions that, despite its increasingly dominant presence in highly specialized industries, 3D printing technology will not meaningfully change the lives of the average person in the foreseeable future.

"I'm so sick of reading the hype," she admits. "Like, 'we can press a button and make anything.' Yes, that is the future and it's coming, but right now it's complicated. Not every 3-D printer can generate every material. Some guy in his garage is not going to be able to print Titanium."

"I don't want to be a naysayer, but these are grandiose notions we should keep at bay," warns Tim Shinbara, technology director at the Association of Manufacturing Technology in McLean, Virginia. Shinbara, who is currently helping create the first crowd-source designed, 3D printed car (to be unveiled at the International Manufacturing Technology Show in October), says people's excitement should not override their common sense.

"3D printing is not that new; we've heard all this before," Shinbara says. "Inventions like the computer changed things, yes, the world progressed, but still, we're not living in a Jetsons world. We're not flying around in cars."

One area that particularly concerns him is 3D printed food.

"Even if it technically works, should we be doing it? If we start creating food instead of growing or harvesting it-that gets a little scary. At a molecular level, does your body accept something that's been artificially and genetically manufactured? Even if it looks the same under a microscope, what will it do to you over 10, 20 years?"

The hype over 3D printing, say technology experts, ignores the potential problems it will create. One significant problem is the legality and ethical ramifications of widespread public use. Right now, additive manufacturing (the technical term for 3D printing) is in its "Wild West" phase, meaning, the laws have not yet caught up with the technology.

An example of this is 3D printed guns. Last year, blueprints for a 3D-printable gun, The Liberator, were posted online and downloaded some 100,000 times before the State Department ordered them taken down.

"If gun control advocates hoped to prevent blueprints for the world's first fully 3D-printable gun from spreading online, that horse has now left the barn about a hundred thousand times," Forbes magazine wrote.

A few months after The Liberator incident, President Obama extended the 1988 Undetectable Firearms Act, which prohibits the manufacture, sale or possession of guns that are undetectable by X-ray machines or metal detectors. Critics protested that 3D printed guns could easily be modified to circumvent airport surveillance machines.

And there are other ethical issues to be considered with 3D printing. Though Daniel Castro, Senior Policy Analyst at the Information Technology and Innovation Foundation in Washington, DC, believes 3D printing's capacity for innovation will ultimately benefit society, he wonders how intellectual property rights will be protected and enforced.

"I don't think we're going to be too worried about consumers printing out Mickey Mouse and Disney being mad about that," says Castro. "We're more likely to be concerned about India or China or another country stealing digital designs using corporate espionage, and then being able to perfectly replicate what's been produced in the US or elsewhere. Governments will have to hold companies accountable for what could be massive intellectual corporate property theft."

Technology gurus like Jack Uldrich, however, say there's no stopping a speeding a train. The choices are get on board, get passed by or get run over, he says.

"If you can print out food, components of homes, body parts as we age, it points to a really interesting future," he speculates. "We'll be treating animals in a humane way, rewriting the rules of society. What if we really don't need to work? In the hands of 7 billion creative people-we can't even begin to imagine how people will use this technology."

Try “The Diamond Age” by Neal Stephenson, 1995.

In the book he explores the techno and sociological ramifications of having tech as 3D printing tho he called ‘em compilers. (using nanotech to lay down the material.)

A good read in itself and great read seeing what kind of world it would be like to live in with the this tech.
