A new 3D printer from Disney's research lab could some day let you print out your own teddy bear. Headlines & Global News reports.
The entertainment giant's research lab recently released footage of a 3D printer that has the ability to print fabric material. The printer, designed by researchers from Disney, Cornell Unviersity and Carnegie Mellon University, uses a mixture of laser cutting and layer printing to create a unique printing method. "The machine builds the object up layer by layer by cutting shapes out of a sheet of adhesive felt, cramming/heating each layer together as it goes.

Organovo has been working on printing functional human tissue since being incorporated in 2007, and first printed a cellular blood vessel in 2010. Since January 2014, it has offeredbioprintedliver tissue (marketed as exVive3D™ liver tissue) for companies to use in drug trials and disease modeling, and it looks as though its bioprinted human kidney tissue will be used for the same tasks, starting sometime in the latter half of 2016.
"Kidney represents an ideal extension of capabilities to 3D bioprint organ tissues that can be tremendously useful in pharmaceutical research," Keith Murphy, Organovo's chairman and CEO, said via press release. “The product that we intend to build from these initial results can be an excellent expansion for our core customers in toxicology, who regularly express to us an interest in having better solutions for the assessment of human kidney toxicity.

A tortoise has been given a 3D printed prosthetic shell to protect her own, as she suffers from a painful disease which has caused it to wear away. The Telegraph reports.
Roger Henry, a Colorado Technical University student, designed the tortoise a prosthetic shell, and 3D printed it with assistance from The 3D Printing Store in Denver.
"I heard this tortoise was damaged, needed some help and it seemed like the right thing to do," Mr Henry told the Denver Post. "We basically told the software that this is a piece of cloth. Therefore, drape it onto the tortoise."
The lightweight prosthetic shell attaches using velcro, and will only need to be worn when Cleopatra is around other tortoises. Her shell is expected to regrow within a couple of years thanks to the optimum temperature and a diet including dandelions and cactus.

With the announcement of a breakthrough technology that accelerates 3D printing speeds by a factor of up to 100, you may soon encounter a 3D printer in the most banal of everyday places: your dentist?s office. Quartz reports.
This means that dentists can now print a tooth in 6.5 minutes,? explained Joseph DeSimone, the CEO of the 3D printing company Carbon3D and a professor of chemistry at the University of North Carolina at Chapel Hill, at the TED Conference in Vancouver last week.
The 3D printing innovation is cutting edge, but the ability to reproduce a tooth while you wait in the dental chair is actually not new. ?It?s been around for about 30 years,? explains Dr. Sharde Harvey, a New York City-based dentist who been using the method called CEREC (Chairside Economical Restoration of Esthetic Ceramics) since 2005.
Developed in the University of Zurich, CERAC is more akin to computer-assisted sculpture than printing. While 3D printing creates an object one micro layer at a time, CEREC carves out or ?mills? a new tooth from a piece of porcelain aided by scanners and 3D modeling software.
Both methods allow dental practitioners to replace teeth, crowns, veneers, and inlays in a single sitting. The advantage of 3D printing over milling is that the process is better able to custom manufacture an object with intricate details?think about a tooth?s irregular grooves, crannies, and valleys. The problem with 3D printing was that it used to take a very long time.
Now the race is on to come up with faster, feasible 3D printing techniques. Barely a week after Carbon3D?s unveiling, the Australian company Gizmo 3D announced that they?re working on a ?super fast SLA [stereolithography] style 3D printer? that challenges Carbon3D?s print speeds.

3-D printing hobbyists have managed to print up a functioning Colt CM901 assault rifle, what’s said to be the heaviest caliber rifle to ever roll off the presses of a 3-D printer. [via TIME]
Hobbyists at PrintedFirearm.com posted an animated GIF of the 3-D printed rifle firing off several rounds at a shooting range.
The CM901 fires 7.62 mm rounds, a heavier caliber bullet than that of the AR-15. The gun also recoils with greater force, requiring gunsmiths to print up sturdier plastic parts that can withstand the stresses of multiple rounds. After a period of trial and error, the team claims the CM901 can fire off several rounds “with little to no issues.”
In other words, hobbyists in the 3-D printed arms race, for better or worse, are getting more bang for their buck.

A 3D printing process that harnesses light and oxygen has been demonstrated at the Ted conference in Vancouver. The BBC reports.
Carbon3D said its "game-changing" process could make objects such as car parts, medical devices or shoes.
The technique was inspired by the film Terminator 2, in which the T-1000 robot rises from a pool of metallic liquid.
On the Ted stage, the Carbon3D machine produced a plastic ball from a pool of resin in 10 minutes.
"It would traditionally take up to 10 hours to print this," Carbon3D chief executive Prof Joseph DeSimone told the audience.
He said that current 3D printing methods had some fundamental flaws.
"First up, the name is a misnomer. It is really 2D printing over and over again," he said.
The process is also often very slow.
"There are mushrooms that grow faster than some 3D-printed parts," he joked.
And finally the objects created by traditional 3D printing are often mechanically weak because they are made up of multiple layers.
His method is 25 to 100 times faster and can print solid final parts. It can, he said, potentially be up to 1,000 times faster.
It works by applying different levels of light and oxygen to a pool of resin. Light hardens the resin, while oxygen stops hardening.
By intricately controlling levels of each, the resin can be forced into complex shapes.

Understanding of the complexities of tumors and even radiotherapy delivery could soon be revolutionized through the use of 3D printing, claim researchers who are pioneering a number of groundbreaking technologies. Medscape reports.
A number of research teams around the world exploring the use of 3D printing in a number of different areas pertaining to cancer and its treatment.
One use for 3D printing developed at the Institute of Cancer Research and the Royal Marsden National Health Service Foundation Trust, in London, is to produce models of tumors to help calculate the dosage of radiation delivered to a tumor.
The models accurately replicate the shape of a patient's tumor and the surrounding organs to help clinicians achieve the right balance between killing the cancer cells and preserving the healthy tissue.
The aim is to improve molecular radiotherapy by filling the tumor replicas with the same radioactive liquids administered to patients and estimating the likely effects of the treatment.
Originally, the models were handmade, but 3D printing technology offers the potential to substantially improve dosing accuracy in, for example, thyroid cancer, adult neuroendocrine tumors, childhood neuroblastoma, and prostate cancer bone metastases.
"We've seen reports on how 3D printing is being used for prosthetics and to inform surgery, and this research shows it has the potential to improve cancer treatment too ― by helping us to perform complex radiotherapy calculations more accurately," commented Glenn Flux, PhD, head of radioisotope physics at the Joint Department of Physics, the Institute of Cancer Research, and the Royal Marsden NHS Foundation Trust in London in a release.
"We're really excited about this technology and the potential it has for personalizing cancer treatment with highly targeted radiation," he said.

Late last week United States Patent and Trademark Office published a patent filing by Amazon Technologies, Inc. which outlines a method of 3D printing on-demand within mobile manufacturing hubs. According to Amazon, such a setup could save the company time and money on several fronts. 3DPrint.com reports.
By utilizing ‘mobile manufacturing apparatuses Amazon would be able to send an STL file to a mobile unit that’s closest to a customer, providing it with instructions to print out an item which was ordered. When the item has been completed, it could then be within miles of the customer who ordered it and quickly delivered or picked up.
The mobile hubs, according to the patent filing, would include a means to both additively and subtractively manufacture an item. This could include a number of different 3D printing technologies as well as CNC machining tools, which would ultimately reduce Amazon’s reliance on warehouse space as well as the robots and employees needed to sort through these stored items.
Australian researchers say they have created two jet engines using 3D printing in what is described a world-first that has attracted the interest of major manufacturers and engineering firms. [via The Telegraph]
The machines - produced using the template of a gas turbine engine from French aircraft engine maker Safran, which supplies Airbus and Boeing - demonstrated the potential 3D printing had to produce high-quality products, researchers from Melbourne's Monash University said.
"The significance... is the recognition by major manufacturers and engineering companies like Safran and Airbus that the material you can print using 3D metal printing is of aircraft quality and I think that's hugely significant," the university's Ian Smith told AFP.

James Torbett is a senior electronic designer at Kinneir Dufort, the company behind a new pancake art which allows you to put a name and a face to your fare for breakfast. Torbett used digital imaging by combining use of a digital camera with image processing to create pancake likenesses. 3DPrint.com reports.
The real challenge was to create a program that enables the picture to be completed from start to finish within the exact timescale for the overall pancake to cook,” said Ian Hollister, prototyping director at Kinneir Dufort. “Too little time and the darker tones wouldn’t be achieved, too long and the pancake would burn.

A toucan in Costa Rica which lost the upper part of its beak after being attacked by youths looks set to be fitted with a prosthetic replacement. [via the BBC]
Four Costa Rican companies that have volunteered their help say they possess the skills to create a prosthesis for the injured bird.
They say they will use 3D printing to create the first prosthesis of this kind in the region.
In the US, prosthetic beaks have been created for an eagle and a penguin.
The male toucan, named Grecia after the area where it was found, was taken to an animal rescue centre in January.
Pictures of its mutilated beak caused outrage after they were circulated in Costa Rican newspapers and on social media.
A campaign to provide the bird with a prosthetic beak quickly raised thousands of dollars and a number of local companies offered their help.
Four of them, Elementos 3d, Ewa!corps, Publicidad Web and Grupo Sommerus, said on Tuesday that they were confident they could design a suitable prosthetic for Grecia and fit it.
Toucans use their beaks to eat and also to regulate their body temperature.
Veterinarian Carmen Soto, who looks after Grecia at the Zoo Ave rescue centre, said the toucan was recovering well and had even started eating on its own.

Perhaps the best thing about these 3D printing prosthetics is the possible level of customization. Most simply attach to the wrist and feature a mechanical grip (Simply flick your wrist up or downwards, and the fingers move inwards or outwards), but they can be customized to fit any portion of the arm as well and even preform a series of other actions. But the owner of the most impressive 3D printed prosthetic is undoubtedly the 17-year-old Diego Corredor, from Colombia. Why? Because he can play guitar with it.

e-NABLE was inspired by two people — a prop maker from the USA and a carpenter from South Africa — that came together from 10,000 miles apart to create
What originally started out as a couple of guys who created something to help one child in need as grown into a World wide movement of tinkerers, engineers, 3D print enthusiasts, occupational therapists, university professors, designers, parents, families, artists, students, teachers and people who just want to make a difference.
There are people around the Globe – 3d printing fingers and hands for children they will never meet, classes of high school students who are making hands for people in their local communities, a group of people that are risking their lives to get these devices onto people in 3rd World countries and new stories every day of parents working with their children to make a hand together.
It turns out that one my relatives in Maine (he would rather not be named) is part of this grassroots movement and a member of the e-NABLE network. I asked him how it works for him:
I have printed several hands now, but have not had machines reliable enough to accept a match with a person. I am working on improving the design of the "Raptor Reloaded" model and experimenting with a number of different materials. NinjaFlex looks very promising in a variety of ways and I am finding a Taulman filament that is a blend of polymer and nylon (PCTPE) is also quite strong yet has a flexibility component that may well prove useful.
A person (most often a child but by no means exclusively) needs an upper limb of a particular size and shape. Whether through birth issues or accident, e-NABLE tries to fit them with a hand that can grasp an object by a simple up and down movement from the wrist, elbow or even shoulder as may be needed.
Some people are also working on myoelectric devices as well which is quite exciting. Anyway, when a need is found, that person gets matched with a maker such as me, who then builds them a device according to their particular size and need.
This is best done in person, but many hands have been made in one place, and sent to another with fine success. To that end, e-NABLE organizes all the intermediary needs including record-keeping, matching, codes of conduct and standards of build integrity, not to mention the designs.
Software called the "Hand-o-matic" helps to scale, size and determine the best individual design as best it can. The maker uses photos and measurements if the actual person is not nearby.
One of the best parts comes in here, too. All participants pay nothing. As a maker, I supply the limb at my own cost and all aspects of this system are donated. Nobody pays, nobody charges. It is really a wonderful outgrowth of technology allowing people to benefit in ways that were previously unknown. I encourage you to check out the e-NABLE websites and forums to see how it all plays out. Jon Schull at the Rhode Island Institute of Technology is one of the movers and shakers so a Google search there will undoubtedly yield a wealth of other info as well.

Doctors at the Feinstein Institute for Medical Research in New York, say 3D printing can be used to create a biodegradable tracheal segment containing a patient’s own cells to aid them in complex reconstruction surgery. [via 3DPrint.com]
Making a windpipe or trachea is uncharted territory,” Todd Goldstein of the Feinstein Institute says. “It has to be rigid enough to withstand coughs, sneezes and other shifts in pressure, yet flexible enough to allow the neck to move freely.
With 3D printing, we were able to construct 3D printed scaffolding that the surgeons could immediately examine and then we could work together in real time to modify the designs.
MakerBot was extremely helpful and consulted on optimizing our design files so they would print better and provided advice on how to modify the MakerBot Replicator 2X Experimental 3D Printer to print with PLA and the biomaterial.
