The next generation of desktop 3-D printers might do away with the excruciatingly slow process that current units use. Researchers have unveiled a printer that replaces the current extruder nozzle that squeezes out melted plastic one layer at a time with light and oxygen.
The makers of the Carbon3D printer have demonstrated a technique they call continuous liquid interface production (CLIP), which grows 3-D printed parts out of a liquid resin bath. Ultraviolet light and oxygen work to build a stronger part in layers just tens of microns wide. Build times can be reduced from hours to minutes, they say.
“Right now the technology is still too expensive for a mass audience — a good unit can cost thousands of dollars — but the history of breakthrough innovations suggests the price will soon drop significantly. Because of its versatility, the technology has the potential to destabilize more industries than just the entertainment sector. But they can all learn something from the music industry’s long struggle against piracy.
Both P2P downloading and 3D printing revolve around computer files packed with intellectual property — performing artists’ copyrighted songs, in the former, or CAD files that contain firms’ industrial blueprints, in the latter. These files are shared and posted all over the Internet. And just as with music, 3D printing is hard to track because it can occur in the privacy of someone’s home or office; requires little manufacturing equipment or investment beyond the device itself; and features a robust, supportive online community that generally doesn’t view the activity in immoral terms.”
“Batmanghelidj says that BarTender’s ability to adapt to any label printer creates another differentiator, too. “In an FDA-controlled environment, the labeling process is very complex,” he says. “For example, if a label change is needed, one person makes the change, it’s then reviewed and signed off by several other people, and there’s a very intricate process for validating that all the appropriate labels were updated and all the old labels were decommissioned. Without our solution, which includes the BarTender bar code print and design engine, our customers would have to manually manage hundreds of label files, which is not only time-consuming but highly error-prone. In one example, we helped a customer reduce the number of managed label files from 5,000 down to just five templates.”
Leave it to Disney and its technologies to make you part of the show – even when you are far from their parks
At a mall
Love the bit where the guy says on his phone "I think I am being shadowed by Goofy". How did person at other end react?
Also geeks, sure you know what Umbra and Penumbra are?
By making you part of a show
Mickey hats with LEDs allow audiences to Glow with the Show. BTW there is also a Minnie Mouse-inspired headband, a Mickey Mouse glove and, my favorite, a magical wand that reminds me of Sorcerer Mickey.
Everywhere you go
You can show off your Disney Side with your mobile phone
The metals producer, more than 125 years old, makes parts for gas turbines, the engines that plane manufacturers such as Boeing and Airbus install to give planes the power to get you to your next meeting. The problem? All that testing takes time. Between tooling, development, and casting, it used to take Alcoa upwards of a year to manufacture one of the nickel-alloy parts that go into an engine, where it must withstand temperatures of up to 2,000˚F. Then the company caught wind of something called additive manufacturing—better known as 3-D printing.
Alcoa started toying with the technology in the early 1990s. But it wasn’t until the past few years that the company began using it to create the dies that shape engine parts. With additive manufacturing, Alcoa has managed to cut in half the time required to develop the process and manufacture the part. Better still, it managed to cut the cost of the process by about 25%. “We’re really at the beginning of what I would call a second Industrial Revolution,” says Klaus Kleinfeld, Alcoa’s CEO. “You go from idea to product in no time. It’s almost like production at your fingertips.”
Although most of its printing will be done in-store, Leigh says, Staples will outsource large-scale jobs to the facilities of 3D Systems, which is running the New York and L.A. trials and has been selling 3D printing services since 2010.
If its U.S. test pays off, Staples says it will consider placing 3D printers in other stores and offering similar services online. Leigh says he wants to showcase 3D printing for casually interested customers, letting them play with the machines and use an in-store photo booth to print their faces on customized action figures.
The Kosair Children’s Hospital physician turned to the University of Louisville’s engineering school for help and was able to secure the use of a MakerBot 3D printer. With the 2D CT data turned into a 3D model and blown up to twice the normal size, it was far easier for the medical team to see the problems they were dealing with. Roland was born with a hole in his heart, with a deformed aorta and pulmonary artery. Because the heart must be stopped for surgery, the timing is critical — not being able to see an organ until you open the patient up means less time for doctors to find and repair damage.
The use of a 3D model for a pediatric heart surgery is a first for KY, but it’s not the first time 3D printers have been used to create models of surgical procedures. According to Tim Gornet, manager of the University of Louisville’s Rapid Prototyping Lab, the engineering school has already worked with doctors to create models of tumors and spinal defects. The total cost of printing up the model on a MakerBot? About $600.
Since founding The Sugar Lab in 2012, the husband-and-wife team have used crystallized sugar to print everything from intricate lattices that dissolve in cocktails to delicate replicas of an extinct orchid, scanned from the Smithsonian archives. They've also collaborated with Duff Goldman of Baltimore's Charm City Cakes to create a custom wedding-cake stand made of interlocking hexagons, a design that would be impossible to make by hand. The couple created their tech prototype by modifying an existing printer by 3D Systems (which recently purchased The Sugar Lab). The machine works by wetting dry sugar to create a frosting-like texture; repeated thousands of times, the process slowly builds a three-dimensional structure. "There's already a cultural expectation that dessert should be sculptural," says Liz, "so sugar is a great place to start introducing 3-D printing into people's lives."
Cognizant on this blog and Infor on the Deal Architect blog have their badges in animated GIF file format. Here come their physical cousins. From their Kickstarter pitch
“We've been working over the past several months on a way to print animated gifs onto lenticular cards. Each sheet of lenticular film has many tiny lenses, which allow us to print around ten frames of animation onto small cards. It's been around since the 1940s, but has mostly been used for children's toys.
We've been doing tons of test prints with different materials and different types of film, and have started working with a lenticular manufacturer that will allow us to do custom prints. We've also been building out a website where you can upload a gif, select a portion to print, and order a gif card in a variety of sizes. We've been sharing and showing these gif cards among friends — it's been really fun, and addictive to play with."
I have written about previous GE versions of the sleigh. This year “GE scientists are turning to the crowd and the power of 3D printing to design a whole new sleigh for Santa that will ensure he makes all of his deliveries this holiday season.”
Some of the entries already submitted on GrabCAD’s site
In the meantime, as more of holiday gift requests and fulfillments flow through ecommerce sites BusinessWeek describes Santa's other sleigh
"At mighty Amazon, the omniscient computer program that practically runs the company’s supply chain is known internally as the Mechanical Sensei. The program tracks all the items and orders coursing through Amazon’s systems. It makes millions of small decisions, such as how much of a particular product Amazon should buy, and—given the geographic dynamic of demand for that particular —where in its massive network of fulfillment centers to store it.'
