3D printed ears to transplant

3D printed ears are going to be transplanted on children in India, hopefully restoring their hearing!

At this rate it looks like in a number of years we might be able to order 3D printed body parts online and having them delivered to our local hospital/clinic for transplants 🙂

The BBC will be airing an exciting special BBC Inside Out London special in which the show’s host, Dr. Ranj Singh, pays a visit to the lab of Professor Alex Selfalian at University College London where he and his team are in the process of 3D printing ears made from real human tissue.

As you’ll see in the preview clip below, the lab uses uses accurate scan data to 3D print an ear replica from a nanopolymer.  The print is then sterilized and implanted under the skin of a patient’s forearm, where it acts as a scaffold for human tissue.  Skin and blood vessels grow in around the print over the course of four to eight weeks, at which point, a plastic surgeon removes the ear and places it on the head.

The scientists at UCL have already tested the growth procedure on rats and, in the next few months, they hope to perform their first human trials in Mumbai, India, where twelve children are awaiting the surgery.  If the implants are a success, the procedure could replace the current method for handling this congenital deformity, which requires shaping rib cartilage into the shape of an ear and three or four different surgeries.

3D printed military grade drones

The future US military drones look like they’re going to have a completely 3D-printed body and an Android phone for a brain. All for just $2500 a pop, with a wait of just over a day!

We have 3D printed keysguns and shoes — now a research team at the University of Virginia has created a 3D printed UAV drone for the Department of Defense.

In the works for three years, the aircraft, no bigger than a remote-controlled plane, can carry a 1.5-pound payload. If it crashes or needs a design tweak for a new mission, another one can be printed out in a little more than a day, for just $2,500 (£1533). It’s made with off-the-shelf parts and has an Android phone for a brain.

“We weren’t sure you could make anything lightweight and strong enough to fly,” says David Sheffler, who led the project. Sheffler is a former engineer for Pratt & Whitney and Rolls-Royce who now teaches at the university. After he created a 3D printed jet engine in one of his classes, the MITRE Corporation, a DoD contractor, asked him to create a 3D printed UAV that could be easily modified and built with readily available parts.

The first prototype, the orange and blue model seen in the video above, was based on a conventional radio-controlled (RC) aircraft made of balsa wood, which is much lighter and stronger than the ABS plastic used in the university’s 3D printers. The same plane made of plastic would have weighed five times as much as the wood version. “You’re printing out of a material that’s really not well-suited to making an airplane,” Sheffler explains. On top of that, the way 3D printing works –building things in layers — led to structural weaknesses in the aircraft.

To account for those downsides, Sheffler’s team reworked the design. They settled on a “flying wing” design, in which the whole aircraft is basically one big wing, and called it the Razor. The latest (third) prototype is made of nine printed parts that click together like Lego. The centre of the plane is all one piece, with a removable hatch that offers access the inner cargo bay. All of the electronics live in there, including a Google Nexus 5 smartphone running a custom-designed avionics app that controls the plane, and an RC-plane autopilot that manages the control surfaces with input from the phone. The Razor’s wing structure is one piece, with an aileron, winglets, and mount for the small jet engine that clip on.

The aircraft, with a four-foot wingspan, weighs just 1.8 pounds. Loaded with all the electronics gear, it comes in at just under 6 pounds. That lets it fly at 40 mph for as long as 45 minutes, though the team’s working to get that up to an hour. An earlier prototype could top 100 mph, and the team believes the plane could hit 120 mph, at the cost of a very quickly drained battery.

It can carry 1.5 pounds, so attaching a camera to it would be no problem. The batteries take two hours to fully charge and are easily swapped out, so if you’ve got three or four packs on hand, the Razor can be in the air nearly continuously. The plane can be controlled from up to a mile away, or fly on its own using preloaded GPS waypoints to navigate. The team uses the Nexus smartphone’s 4G LTE as well, meaning commands could be sent from much farther away, though FAA guidelines have kept them from long-distance testing.

Here’s where the 3D printing really comes in handy: The design can be modified — and reprinted — easily, to be bigger or smaller, carry a sensor or a camera, or fly slower or faster. The plane can be made in 31 hours, with materials that cost $800 (£490.75). Electronics (like the tablet-based ground station) push the price to about $2,500 (£1,533). That’s so cheap, it’s effectively disposable, especially since you can make another one anywhere you can put a 3D printer. If one version is flawed or destroyed, you can just crank out another.

Though the team’s research contract has run out, they’re hoping to get another one next year. If Sheffler’s right about how the technology will evolve, MITRE and the DoD would be wise to extend the partnership. “3D printing is at the phase where personal computers were in the 1980s,” Sheffler says. “The technology is almost unbounded.”

“This program was really tasked with showing what is possible.”

3D printed telescopic golf club

If you have any creative marketing ideas (like the one below) which can be developed with 3D printing, send us a message to see how we can help turn your ideas into reality!

Golf, it is a sport of inches. One little pebble on the ground can be the difference between winning and losing. Golf clubs come in different sizes, with multiple shaped heads, each with different purposes. The typical golf clubs are made out of steel, titanium, or carbon fiber, as they need to be very strong in order to handle the repetitive striking of hard balls.

One young man, named Duncan K. Anderson decided to try something new. Anderson, a student at the Lahti Insitute of Design, was assigned with creating a promotional tool for a design agency named Webb deVlam. The task was to pick a product that symbolized the company and design the packaging accordingly. Anderson came up with the idea of a 3D printed golf putter.

This wasn’t just any putter though, it was a telescopic club that would be packaged with 3D printed balls as well.

“Golf was chosen as a subject as it’s a game of bonding, experience and rejuvenation,” explained Anderson. “3D printing was chosen as it exemplifies the structural and technological capabilities of the company and is a product that would interest corporate clients.

The golf club, and the balls were 3D printed, while the packaging was made out of different colors of cardboard. Anderson had tried to print his design on an older 3D printer that he had access to, but found that he wasn’t able to print the telescopic design all in one piece on the machine available. So, Anderson went to a company called 3D Print UK for some help. Using 3D Print UK’s industrial level selective laser sintering machines, Anderson was able to have the golf club set printed out exactly how he had envisioned. The set is 3D printed using a nylon material that is very durable.

Anderson entered his creation into the Student Starpack 2014 competition and came away with several awards: The Starpack Gold Award, Webb deVlam Sponsored Award & Nampak Champion Award.

Webb deVlam felt that Anderson’s project was everything that they had hoped for when providing the school with their request.

“Showed true understanding of the brief and executed it brilliantly,” said Webb deVlam. “Every usage point of the product – from opening to playing, related back to Webb deVlam. Both graphically and structurally excellent. Epitomizes who we are as a packaged product. Hands-down winner!”

While you probably won’t see 3D printed nylon golf clubs on the golf course anytime soon, the idea and the design that Anderson came up with is quite phenomenal. What do you think of this design? Discuss in the 3D Printed Golf Club forum thread on 3DPB.com.
