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.

watched the rollout of the new spaceX vehicle

they had a number of its components out to show the crowd
one was their latest rocet thruster
the big ones used for landing this thing

turns out its 3d printed

Printing the metals of the future


3-D printers can create all kinds of things, from eyeglasses to implantable medical devices, straight from a computer model and without the need for molds. But for making spacecraft, engineers sometimes need custom parts that traditional manufacturing techniques and standard 3-D printers can't create, because they need to have the properties of multiple metals. Now, researchers at NASA's Jet Propulsion Laboratory in Pasadena, California, are implementing a printing process that transitions from one metal or alloy to another in a single object.

"You can have a continuous transition from alloy to alloy to alloy, and you can study a wide range of potential alloys," said R. Peter Dillon, a technologist at JPL. "We think it's going to change materials research in the future."

Although gradient alloys have been created in the past in research and development settings, this is the first time these composite materials have been used in making objects, such as a mount for a mirror, said John Paul Borgonia, a JPL mechanical engineer.

Why would you need to make a machine part like this? Say you want a metal object where you would like the ends to have different properties. One side could have a high melting temperature and the other a low density, or one side could be magnetic and the other not. Of course, you could separately make both halves of the object from their respective metals and then weld them together. But the weld itself may be brittle, so that your new object might fall apart under stress. That's not a good idea if you are constructing an interplanetary spacecraft, for example, which cannot be fixed once it is deployed.

SpaceX Taking 3D Printing to the Final Frontier

By Elizabeth Howell,
Space.com Contributor
| August 21, 2014


The private spaceflight company SpaceX wants to launch astronauts into space in the coming years, and it will enter the final frontier with an innovative technology: 3D printing.

California-based SpaceX is using additive manufacturing, as 3D printing is also known, to build the emergency escape rockets on its new manned Dragon spacecraft. The capsule, known as Dragon Version 2, is SpaceX's entry in NASA's competition for commercial manned spacecraft to ferry astronauts to and from the International Space Station.

SpaceX sent its first 3D-printed part into space early this year. The part, a rocket engine main oxidizer valve, flew aboard SpaceX's Jan. 6 launch of a Falcon 9 rocket carrying the commercial Thaicom 6 telecommunications satellite to orbit. The valve flew inside one of the rocket's Merlin 1D engines.

[video at the link]


"The mission marked the first time SpaceX had ever flown a 3D-printed part, with the valve operating successfully with high-pressure liquid oxygen, under cryogenic temperatures and high vibration," SpaceX representatives wrote in a statement.

The concept of 3D printing in space has received extensive attention in industry circles in recent months. NASA plans to send a 3D printer produced by California-based company Made in Space to the space station this year, and the European Space Agency has mused about using 3D parts to build lunar bases. Despite those plans, a recent National Research Council report said the technology is still in its infancy and that the materials science behind manufacturing in space is poorly understood.


SpaceX has used 3D printing to build the SuperDraco rocket engine for the company's Dragon Version 2 manned spacecraft. The eight SuperDracos on the capsule are designed to double as a landing system, or as an escape system in the event of a launch emergency.
Credit: SpaceXView full size imageSpaceX has spent three years evaluating the fast-growing technology, particularly for use on the Dragon spacecraft. A 3D-printed SuperDraco engine chamber, which will be used in the escape system, passed a firing test at full thrust in late 2013.

"Printing the chamber resulted in an order of magnitude reduction in lead time compared with traditional machining — the path from the initial concept to the first hotfire was just over three months," SpaceX representatives stated.

The 3D valve inside the Falcon 9's rocket engines will also be more efficient to manufacture, SpaceX added. After extensive testing, the 3D part is now certified to fly alongside regularly manufactured materials.

"Compared with a traditionally cast part, a printed valve body has superior strength, ductility and fracture resistance, with a lower variability in materials properties," company representatives stated. "The [valve] body was printed in less than two days, compared with a typical castings cycle measured in months."

Just to add to Ben's post

"the SuperDraco engine chamber is manufactured using state-of-the-art direct metal laser sintering (DMLS), otherwise known as 3D printing. The chamber is regeneratively cooled and printed in Inconel, a high-performance superalloy that offers both high strength and toughness for increased reliability."
