How 3D Printing is Changing the Face of the Medical Industry

The list of medical applications for 3D printing was originally compiled by the team at 3D model marketplace CGTrader and has been edited for publication here.

Recently 3D printing has been a hot mainstream trend, but there are thousands of people who are still not aware of this mind-blowing technology. Obviously, 3D printing is being carefully watched by scientists, designers, futurists, and hobbyists. No doubt, it will change our lives; 3D printing is already reshaping them. In the long run, 3D printing may have the most impact in the medical field, where extrusion of living cells instead of plastic material in a 3D printer has led to bioprinting.

Here is a completely mind-blowing list of the top 9 ways 3D printing has already changed all the branches of the medicine and what to expect in the future. Moreover, this article touches upon a controversial topic of artificial organs. Keep reading!

1. 3D Printed Hearing Aids

Thousands of people do not realize that they have already become a part of 3D printing revolution by simply wearing hearing aids.

98% of hearing aids (more than 10 million) are 3D printed today. Hearing aid manufacturing began to adopt 3D printing technology in 1998 and it has been a significant improvement to manufacturing. The process has been shortened to 3 steps: scanning, modeling, and printing. One machine is able to produce 30 hearing aids in one hour and a half.

2. Digital Dentistry Brings 3D Printing Into the Dental Office

3D printing’s contribution to the dental industry has been game-changing. Scientist Andrew Daewood, who works in London’s Wimpole Street, notices that before the 3D printing has become the mainstream, “dentists have been using it for 10 years, to make things that really can’t be made in any other way.”

3D printing helps to improve quality and speeds up the production. Technology enables the customer to get a transparent 3D printed teeth aligner for day-to-day use, on one’s way to the dentist 3D printer is already printing out a new dental implant as well as dental crowns, bridges, stone models and a variety of orthodontic appliances.

3. 3D Printing Body Parts and Bone

Earlier this year, an American patient received a radical surgery in which 75% of his skull was replaced with a 3D printed implant. This material was not only biocompatible but also a bone-like. Scott DeFelice, President and CEO of Oxford Performance Materials, announced that his company has serious plans that between 300 to 500 patients in the U.S. alone could have skull replacement surgeries each month.

Last year an 83-year old woman has received the very first titanium jaw implant manufactured with 3D printer.

In another story, a 3D printed biopolymer of windpipe was surgically sewn as a splint to open a baby’s airways. After 2 to 3 years it will be fully absorbed in the body.

4. The Miracles of Prosthetics: 3D Printed Face and Children Hands

Injuries and disease can cause debilitating health conditions for people, to the point where a prosthetic limb or other body part is necessary to maintain quality of life.Thanks to 3D printing, prosthetics have become easier to customize and produce. Here are three particularly inspiring cases.

Eric Moger was the first person to start a life once again with 3D printed face.

A famous Robohand project has proved that anything is possible. The idea was a goal to reach by Richard Van As from South Africa and he finally come up with the concept how to produce necessary hand prosthesis quickly, quite cheaply, and make it accessible to the wide society.

Meet Buttercup, the first and only bird that has 3D printed leg prosthesis.

Thanks to 3D printing and devoted designers, Buttercup has experienced the freedom of walking for the first time. Moreover, this duck is the worldwide superstar, that got an award for honours. Just creepy amazing.

Get Rid of Itchy and Stinky Plaster Casts!

Were you jealous of kids who broke an arm but then got all their friends to sign their cast? With 3D printing technology, the traditional plaster cast is being replaced by a light, breathable, washable and recyclable design. And, of course, stylish.

In the U.S., a bone fracture occurs every 5 seconds. Enter the Cortex Exoskeleton cast designed by Jake Evill, a graduate from the Architecture and Design School in New Zealand. With a 3D scan, the cast can be 3D printed onsite at the emergency room.

5. 3D Printing and Growing a Bionic Ear

When researchers from Princeton and John Hopkins get together, expect something big. In this case, a team of researchers developed a bionic, artificial ear. With the help of 3D printing, the team created a skeletal structure which is seeded with cartilage cells, and 10 weeks later, you have a fully formed ear!

6. 3D Printing Stem Cells Paves the Way to Artificial Organs

3D printing enabled a group of Heriot Watt University scientists to produce clusters of embryonic stem cells. The scientists used the method of valve-based printing in order to keep these cells in high level of viability, to stay accurate to produce spheroids of uniform size and to maintain their pluripotency that addresses to differentiation into any other cell type.

In the picture above you can see aggregated embryonic stem cells after 24 hours (left) and after 48 hours (right). Artificial organs are still in the near future, but this achievement is extremely significant for drug testing purposes while using artificial human tissue or even printing cells directly inside the body.

7. 3D Printing Endless Blood Vessels Threads

Scientists from the Fraunhofer Institute in Germany developed a technique to 3D print artificial biological molecules to form the shape of blood vessels. This technology is still quite imprecise for the fine structures of capillary vessels, so the scientists use the laser to zap the molecules and to form the material.

In other findings, UPenn and MIT researchers found sugar as the best agent to 3D print blood vessels without any seams.

8. New Skin, Courtesy of 3D Printing

Skin graft transplantation is nothing new in the medicine, but now 3D printing technology is enabling scientists to produce artificial skin. Researchers at the University of Toronto have developed a method of loading skin cells and various polymers into 3D printer to create thick layers of skin.

In other research, scientists from the Institute of Regenerative Medicine at Wake Forest University in Winston-Salem, North Carolina aim to print skin directly onto burn wounds. Professor James Yoo and his team were highly inspired to develop a portable bioprinting system to help address injuries in the battlefield, where around 30% of injuries involve skin damage.

9. 3D Printed Organs: A Fiction or The Great Achievement of The Next Decade?

18 people die everyday in the U.S. waiting for an organ transplant. Some researchers have embarked on a bold goal of 3D printing artificial organs.

In one example, surgeon Anthony Atala demonstrated an early-stage experiment at a 2011 TED Talk, where he printed a prototype human kidney.

In other research, Wake Forest Institute For Regeneration works on more than 30 different replacement tissues and organs, including bladder, cartilage, trachea and heart healing therapies. Using similar technology to Atala, a young patient received an engineered bladder transplant, the first lab-grown organ to be implanted into a human.

The world’s first artificial liver is already on its way. A team at Heriot Watt University led by Dr. Will Shu are running experiments with this goal in mind, again using 3D printing in the manufacturing process.

Finally, San Diego-based Organovo team has already managed to create micro-livers that are half a millimeter deep and and 4 millimeters wide. The researchers used a gel to build three types of liver cells and arranged them into the same kind of 3D cell architecture found in a human liver. The company’s ultimate goal is to create human-sized structures suitable for transplant, but they might need more capital.

Shape Up Medical School! 3D Printing Instead of Human Cadavers

on3dprinting — Thu, 24 May 2012 14:59:45 +0000

Medical School students have long used human cadavers in their training for diagnosis, treatment and surgery before they begin practicing with real patients. With improvements in 3D printing technology, realistic artificial body parts can be produced rather than relying on corpses. The U.S. military is currently evaluating this opportunity.

Such artificial body parts would “ideally not be actual biological tissues,” but instead would consist of materials that could physically simulate the feel of flesh and bone. Success in printing out entire body part sections containing bone, muscle, skin and blood vessels could lead to lower medical training costs and cut back on the need for animal or human cadavers.

“If such technology were possible, a wide variety of human anatomy sections could be printed on demand,” according to a U.S. Defense Health Program solicitation for small business issued on May 11.

The 3D printed artificial body parts would also ideally allow for normal CT or MRI medical scans, so that physicians could practice interpreting the scan images before diving in with scalpels. The U.S. military effort could also presumably benefit American physicians and medical schools back on the home front.

Innovative and Strange 3D Printing: Chocolate, Stone, Candy, Organs

on3dprinting — Mon, 23 Apr 2012 15:05:07 +0000

3D Printing is mostly known as a method for additive manufacturing of plastic polymer, used for prototyping, creating small tools, and designing works of art. Consumer-ready printers, like MakerBot, enable anyone to be their own mini manufacturing plant – of plastic goods. This is about to change.

Innovative as well as strange raw materials are starting to emerge in the 3D printing landscape.

Chocolate. The ChocoEdge printer lets you “melt some chocolate, fill a syringe that is stored in the printer, and get creative printing your chocolate.” Available at retail for $3940.

Sandstone. D-Shape has a 3D stereolithic printer that can create large-scale structures out of sandstone. ”It prints the structures using artificial sandstone which is sand or mineral dust glued together by an inorganic binder.” More at Fast Company.

Iced Tea and Bone? Two entries from Open3DP that make the strange category are iced tea and bone. Both examples have only been shown in the lab and are not commercial yet.

Candy. CandyFab4000 from Evil Mad Scientist. “Our three dimensional fabricator is now fully operational and we have used it to print several large, low-resolution, objects out of pure sugar.”

Organs. Wake Forest Institute for Regenerative Medicine is experimenting with 3D printed organs. While strange, this has huge commercial potential.
