That was amazing!! I have heart problems and that is just freaking amazing. Of course, Medicare won't ever cover a "printed" heart but it is still cool as shit!

[dill786]

wow...imagine in the not too distant future, if you ever needed your prescription you wont need to go to a chemist anymore, just print out the medication, awesome if you live in the outback in Australia...

[dill786]

Since reading this thread, I started digging into the 3D printing industry and what I've learned is that I need a replicator, so it's on the way.

That's right, thanks to you all and this thread, I will soon have a 3D printer. Hopefully it's here by June 1.

awesome smokes !!!

cant wait to see it all rigged up he-hee !!

pretty cool smokes!

was reading about a consortium making meat products. in the near future the only steak youll be able to afford will come out of one of these

Baby's Life Saved with 3D Printing

When April and Bryan Gionfriddo brought home their newborn son, Kaiba, in October 2011, he seemed like a healthy baby. But one night, when the family was out to dinner, Kaiba stopped being able to breathe and turned blue. Bryan laid Kaiba, just 6 weeks old, on the restaurant table and performed chest compressions on him before he was rushed to the hospital.

After 10 days, Kaiba was sent home, but he turned blue again two days later. That's when doctors realized Kaiba had a rare condition called tracheobronchomalacia, in which the windpipe is so weak that it collapses, preventing air from flowing to the lungs.

Kaiba's case was severe, and his heart would stop beating on a daily basis, April Gionfriddo said. Even after surgeons placed a tube in their child's trachea to help him breathe, and put him on a ventilator, the life-threatening problems continued.

"We were scared," Gionfriddo said. "We didn’t think he was going to leave the hospital."

But researchers at the University of Michigan had been working on a solution to this very problem. They had developed a way to use new technology called 3D printing to create a splint that would fit precisely around Kaiba's airway, holding it open and making it possible for him to breathe. Three-dimensional printers "print" an object by building it in very thin slices, one layer at a time. [Video: How Doctors Made Kaiba's Splint]

"As soon as the splint was put in, the lungs started going up and down for the first time, and we knew he was going to be OK," said Dr. Glenn Green, an associate professor of pediatric otolaryngology at the university.

Traditionally, airway splints have been carved by hand, but this takes a long time, and the splints do not exactly match a patient's airway.

"I'd like to think I'm a pretty good artist, but I can't even come close to matching a picture," Green said.

Kaiba's case is the first time 3D printing has been used to create a medical device that saved someone's life, the researchers said.

3D-printed splint

For years, Green wanted better treatments for patients with severetracheobronchomalacia. Recently, the researchers began work on a 3D-printed splint and had planned to test it in a clinical trial. But when they heard of Kaiba's case, they realized the technology could save the baby's life, and Kaiba became the first patient treated using the procedure. The device received emergency clearance from the Food and Drug Administration.

To construct the splint, doctors made a precise image of Kaiba's trachea and bronchus with a CT scan. Then, using computer modeling, they created a splint that would exactly fit around the airway, said study researcher Scott Hollister, a professor of biomedical engineering at the university. The model was then produced on a 3D printer.

The device is made out of a material called polycaprolactone, and will dissolve after about three years. By that time, Kaiba's windpipe will have grown, reducing pressure on the organ, and the splint will no longer be needed.

A splint like Kaiba's splint can be made in about 24 hours and costs about one-third the price of a hand-carved version, Green said.

Hollister and colleagues are also working to make 3D-printed devices that will aid in ear, nose and bone reconstruction. For these devices, the 3D printer would construct a scaffold that could be seeded with stem cells from fat or bone. These would then grow into tissue around the scaffold. The researchers have tested these devices in animal models.

Earlier this year, researchers at Weill Cornell Medical College reported that they had made a synthetic ear using a 3D printer.

'Doing wonderful'

Gionfriddo said she had doubts about using an untested device in her son, but she and her husband were desperate for solutions. "At that point, we would just take anything and hope it would work," she said.

Twenty-one days after the procedure, Kaiba no longer needed a ventilator to help him breathe. In total, he spent four months in the hospital.

Now at 20 months old, Kaiba is doing "wonderful," said Gionfriddo, who lives in Youngstown, Ohio. "We are so thankful that something could be done for him. It means the world to us."

Kaiba's doctors describe his case in the May 23 issue of the New England Journal of Medicine.

NASA blows $125k on Star Trek 3D FOOD PRINTER

A small company in Austin, Texas, has received a $US125,000 grant from NASA to develop 3D printed food for astronauts.

Systems & Materials Research Coroporation in Austin Texas has already beaten an easy problem – printing chocolate on a biscuit – but its plan under the NASA grant is more ambitious: a fully-fledged nosh synthesiser, perhaps like the food'n'drink replicators used by Star Trek's Captain Picard and his crew.

The prototype will use a combination of 3D printing and inkjet printing. The inkjet will handle “micronutrients, flavour and smell” while 3D printing will be used for macronutrients (the starch that forms the base of the pizza, along with protein and fat).

Why bother? – because if it worked and didn't send astronauts out of the airlock rather than eat the printed pizza, a working setup would mean that a handful of generic ingredients could be carried on manned spacecraft, rather than completed meals.

SMRC is working with the food science program at North Carolina State University and International Flavors and Fragrances on the project. The proposal's abstract is here.

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.

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.
