Here's a video from last week's Maker Faire showcasing technologies for printing out 3D-ish objects using 2D printers: ModelBox turns a 3D model into a series of 2D images you print on acetate and set into a frame to cheaply and quickly prototype/simulate the 3D object; Zebra Images turns 3D models into holograms; and Lynx Laboratories demos its all-in-one 3D scanner.
Elijah sez, "Recent news has been all about the commercial use of 3D printing - from food to weaponry. But recently, doctors at the University of Michigan used quick thinking and 3D printing technology to save the life of a 2-month-old child with a rare disease."
The scaffold was made of a bioresorbable material, polycaprolactone, so it would dissolve and be absorbed by the body after about three years. At this point, his airways should be fully developed and no longer need the stent.
The doctors used high-resolution X-ray scans of one of Kaiba's healthy windpipes to design a computer model for the life-saving brace.
Laser-equipped 3-D printers crafted the device in a few hours, and the university obtained emergency clearance from the U.S. Food and Drug Administration to implant it on February 9, 2012 at C.S. Mott Children's Hospital in Ann Arbor.
"It was amazing. 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 Green.
As the 3D printed gun story unfolds, many (including me) have noted that you can't print ammo. However, you can print shotgun slugs on a 3D printer, but they suck:
Heeszel was surprised at the first two. “I didn’t think it would go through the first piece of wood at all, much less hit anything,” he says. But he also called them more of a novelty than a practical bullet. “I thought the thing was kinda lame, but I realize there’s a lot of novelty with the 3-D printed gun, and I thought it was kind of timely. But overall I think they’re kind of crappy little rounds,” he adds...
“I might be a redneck from Tennessee, but I love the technology,” Griffy says. Griffy, who runs a YouTube account ArtisanTony — where he also shows off a printable knife and buckshot rounds — tells Danger Room he printed the slugs more for their own enjoyment. “Because a real gun shooting plastic bullets is more fun than a plastic gun shooting real bullets,” he says. “You have to spend six hours printing a barrel that you’re going to use one time, and it’s not as much fun. It’s more about the enjoyment and the sport. And if you’re having to labor that much, then the enjoyment goes away.”
Griffy says he printed the slugs with a Solidoodle 3 3-D printer — which retails for $800 — using ABS thermoplastic using dimensions from one of Heeszel’s non-printed slugs. Griffy then created the computer-aided design files, converted them to a stereolithography format, and checked the files for inconsistencies with the 3-D printing software Netfabb. He also designed slugs in three sizes. The largest slug takes about an hour to print. The others take about 30 minutes. He also added a lead ball to each slug to give them more weight. The final step was mailing them to Heeszel, who fitted the slugs into hollowed-out — non-printed — shotgun cartridges.
UPDATE: "Vimeo has removed or disabled access to the following material as a result of a third-party notification by The David Foster Wallace Literary Trust claiming that this material is infringing: THIS IS WATER - By David Foster Wallace."
Here's a beautifully made video accompaniment to "This is Water," an excerpt from a David Foster Wallace commencement address to Kenyon College in 2005, in which Wallace exhorts his listeners to empathize with the people around them, using examples and languages so beautifully chosen that they just about break your heart.
But most days, if you're aware enough to give yourself a choice, you can choose to look differently at this fat, dead-eyed, over-made-up lady who just screamed at her kid in the checkout line. Maybe she's not usually like this. Maybe she's been up three straight nights holding the hand of a husband who is dying of bone cancer. Or maybe this very lady is the low-wage clerk at the motor vehicle department, who just yesterday helped your spouse resolve a horrific, infuriating, red-tape problem through some small act of bureaucratic kindness. Of course, none of this is likely, but it's also not impossible. It just depends what you what to consider. If you're automatically sure that you know what reality is, and you are operating on your default setting, then you, like me, probably won't consider possibilities that aren't annoying and miserable. But if you really learn how to pay attention, then you will know there are other options. It will actually be within your power to experience a crowded, hot, slow, consumer-hell type situation as not only meaningful, but sacred, on fire with the same force that made the stars: love, fellowship, the mystical oneness of all things deep down.
Not that that mystical stuff is necessarily true. The only thing that's capital-T True is that you get to decide how you're gonna try to see it.
A Brazilian ad agency has built a campaign for Domino's "Pizza" that uses a heat-sensitive coating on rented DVDs; when the disc is played, the heat from the player heats up the coating and causes it to emit a pizza-like odor; the coating also changes appearance and becomes a picture of a pizza with an ad for Domino's.
In partnership with 10 video rental stores in Sao Paulo and Rio de Janeiro, the brand used rented DVDs as media. About 10 discs each of 10 different new release titles such as Argo, 007, Dread And Dark Knight were stamped with thermal ink and flavored varnish, both sensitive to the heat.
While people were watching the movie, the heat of the DVD player affected the disc. When the movie ended and they ejected the disc, they smelled pizza. They also saw pizza: the discs were printed to look like mini pies, and carried the message: "Did you enjoy the movie? The next one will be even better with a hot and delicious Domino's Pizza."
A mechanical engineer (awesomely) named Anjan Contractor has won a NASA grant to prototype a 3D printer for food -- specifically pizza. It will lay down layers of food and flavor powder and melt them together; the powders are room-temperature stable for long periods and can be made from relatively abundant, sustainable foodstocks like insects and soylent green. He prototyped the concept with the 3D chocolate printer in the video above, and he holds out hope that food-printing could solve world hunger by allowing billions to feast on low-wastage, low-energy-input, low-carbon-footprint foods that are printed to order.
Contractor's printer is RepRap based, and is open source hardware; he promises to keep the plans open and free.
I suspect that there's a lot of nutritional subtleties lost when you turn food into processed elements that are recombined (in the same way that beta-carotene in carrots is reliably shown to have health benefits, while beta-carotene supplements are far more questionable). But as a form of food processing, it certainly is exciting!
Pizza is an obvious candidate for 3D printing because it can be printed in distinct layers, so it only requires the print head to extrude one substance at a time. Contractor’s “pizza printer” is still at the conceptual stage, and he will begin building it within two weeks. It works by first “printing” a layer of dough, which is baked at the same time it’s printed, by a heated plate at the bottom of the printer. Then it lays down a tomato base, “which is also stored in a powdered form, and then mixed with water and oil,” says Contractor.
Finally, the pizza is topped with the delicious-sounding “protein layer,” which could come from any source, including animals, milk or plants.
London impressario Mat Ricardo writes in with news of the next London Varieties show:
We had a ball last month at London's Leicester Square Theatre with a show that featured the very silly JOHANN LIPPOVITZ, very naughty EASTEND CABARET, very incredible LISA LOTTIE and the very legendary PAUL DANIELS - plus I risk my life! And you can watch it all right here, for free!
The next show happens on May 30th, and it's going to be a doozy. We've got the astonishing hip-hop improvisor ABANDOMAN, One of the UK's hottest stars of magic PIFF THE MAGIC DRAGON, ORIGINAL STREET DANCE, and veteran variety performer MICHAEL PEARSE, and I'll be debuting one of the most complicated juggling routines I've ever attempted!
There are only three more shows in this limited season, and they're all one time only line-ups. You can book tickets at http://leicestersquaretheatre.ticketsolve.com/shows/873489348/events
And find out more about the next show here. You can find out some of the surprises we have in store for upcoming shows, by following me on twitter @MatRicardo.
The wonderful Retro Report (which revisits popular news stories of the years gone by and follows up on their claims) has posted a great, 10-minute documentary on "crack babies," concluding that the promised crack baby epidemic of kids with gross deformities who couldn't attend regular school never materialized. The documentary says that the entire phenomenon was extrapolated from a single, preliminary study, and that most of the "crack baby" effects were actually the result of low birth weight.
Joe, an engineer from Wisconsin, modified the (now censored) designs for Defense Distributed's 3D printed gun, the Liberator, and printed a working model on a Lulzbot A0-101, a $1,725 consumer printer that is much cheaper and more widely available than the Stratasys Dimension SST printer used by Defense Distributed.
The gun printed by Joe, which he’s nicknamed the “Lulz Liberator,” was printed over 48 hours with just $25 of plastic on a desktop machine affordable to many consumers, and was fired far more times. “People think this takes an $8,000 machine and that it blows up on the first shot. I want to dispel that,” says Joe. “This does work, and I want that to be known.”
Eight of Joe’s test-fires were performed using a single barrel before swapping it out for a new one on the ninth. After all those shots, the weapon’s main components remained intact–even the spiraled rifling inside of the barrel’s bore. “The only reason we stopped firing is because the sun went down,” he says....
...Still, Joe’s cheap homemade gun isn’t without its bugs. Over the course of its test firing, Joe and Guslick say it misfired several times, and some of its screws and its firing pin had to be replaced. After each firing, the ammo cartridges expanded enough that they had to be pounded out with a hammer. “Other than that, it’s pretty much confirming that yes, Defense Distributed is correct that this functions,” says Guslick. “And it’s possible to make one on a much lower cost printer.”
Alan Wexelblat comment on the news that Nintendo has claimed "monetization rights" to fan videos on YouTube that feature tips on playing its games. Some of these videos are incredibly popular, and while their use of Nintendo's creations are often fair use, Nintendo gets to use YouTube's monetization system to advertise on all the videos:
The basic idea is that if someone makes a video of themselves playing a Nintendo game and uploads it to YouTube any ads shown with that video will be of Nintendo's choosing and revenue from it will flow to Nintendo. Ads may appear beside the videos or actually be inserted before and after the video when people go to play it.
The problem here is that "Let's Play" style videos are a pervasive form of information and sharing throughout the industry. I did a quick YouTube search for "let's play" for this blog post and got back over 9.1 million hits. People create these videos to show off their skills, to highlight interesting things they've seen such as game "easter eggs", to provide guides or walk-throughs, or just to share a bit of fun with friends. There are a few professional or semi-professional games writers who use this style of video to promote themselves or their channels, but they are a tiny minority of that nine million.
Nintendo has positioned its action as a gentler approach; rather than trying to ban content related to Nintendo games, they just want to make money off it by changing the video that an individual uploaded. Yeah, um, guys that's not a whole lot better. It also comes across as cheap and lazy - rather than creating content for YouTube that fans and players would want to watch, Nintendo is just taking over other peoples' content.
Here's a clip from an upcoming documentary by a fourth grader who snuck a camera into school to document his horrible school lunches and the vast distance between the food that the school claims to serve and food he and his friends end up eating.
Zachary is a fourth grader at a large New York City public elementary school. Each day he reads the Department of Education lunch menu online to see what is being served. The menu describes delicious and nutritious cuisine that reads as if it came from the finest restaurants. However, when Zachary gets to school, he finds a very different reality. Armed with a concealed video camera and a healthy dose of rebellious courage, Zachary embarks on a six month covert mission to collect video footage of his lunch and expose the truth about the City's school food service program.
I've written before about Moran Cerf -- celebrated neuroscientist, former military hacker, and good-guy bank robber -- who also happens to be a great storyteller. Here's a video in which Cerf recounts some clever and fascinating neuroscience experiments that use neurofeedback to help people resolve competition between different thoughts and wills in their minds. The applications are even more interesting -- mentally controlling a robotic arm, for example.
Here's a video of biologist Brad Josephs's GoPro camera being eaten by a grizzly bear in Alaska; he'd set it out in order to get footage for a BBC documentary. The grizzly went above and beyond the call of duty.
Alex sez, "My colleague Chris Neary and filmmaker Nathan Fitch made this great short film about 11-year-old inventor Andrew Man-Hudspith, who was so intent on getting a 3D printer he made a PowerPoint presentation to convince his parents to help him get one."
Taiwan's Next Media Animation -- basically, news-of-the-weird, made weirder with instant machinima-esque videos -- weighs in on the allegation that Toronto Mayor Rob Ford was caught on video smoking crack.
