Lucas123 writes: Thousands of 3D printer owners who are part of a distributed online network were tapped for a buyer's guide, rating dozens of machines from tiny startups to major manufacturers. Surprisingly, the big-name 3D printer makers were nowhere to be found in the top picks. More obscure companies, like Makergear, a 12-person start-up in Ohio, or Zortrax, a Polish company that began as a Kickstarter project, took top spots in the reviews. The buyer's guide, put together by 3D Hubs, contains five different categories: Enthusiast Printers, Plug-n-Play Printers, Kit/DIY Printers, Budget Printers and Resin Printers. In all, 18 models made it to the top of the user communities' list, and only printers with more than 10 reviews were included in the buyer's guide. 3D Hubs also added a secondary "Printer Index" that includes 58 3D Printers that didn't make it to the top of their categories. Printers with more than five reviews are displayed in the index.

A few days ago you had a chance to ask the people at Hampton Creek about about their products and the science of food. Below you'll find the answers to your questions from a number of Hampton Creek employees.

An anonymous reader writes: NASA reports that the 3-D printer now installed on the International Space Station has finally finished its first creation. After it was installed on November 17th and calibrated over the next week, ground control sent it instructions yesterday to build a faceplate for the extruder's own casing. The process was mostly a success. "[Astronaut Butch Wilmore] Wilmore removed the part from the printer and inspected it. Part adhesion on the tray was stronger than anticipated, which could mean layer bonding is different in microgravity, a question the team will investigate as future parts are printed. Wilmore installed a new print tray, and the ground team sent a command to fine-tune the printer alignment and printed a third calibration coupon. When Wilmore removes the calibration coupon, the ground team will be able to command the printer to make a second object. The ground team makes precise adjustments before every print, and the results from this first print are contributing to a better understanding about the parameters to use when 3-D printing on the space station."

HughPickens.com writes Scientific American reports that simply breathing on money could soon reveal if it's the real deal or counterfeit thanks to a photonic crystal ink developed by Ling Bai and Zhongze Gu and colleagues at Southeast University in Nanjing, China that can produce unique color changing patterns on surfaces with an inkjet printer system which would be extremely hard for fraudsters to reproduce. The ink mimics the way Tmesisternus isabellae – a species of longhorn beetle – reversibly switches its color from gold to red according to the humidity in its environment. The color shift is caused by the adsorption of water vapor in their hardened front wings, which alters the thickness and average refractive index of their multilayered scales. To emulate this, the team made their photonic crystal ink using mesoporous silica nanoparticles, which have a large surface area and strong vapor adsorption capabilities that can be precisely controlled. The complicated and reversible multicolor shifts of mesoporous CPC patterns are favorable for immediate recognition by naked eyes but hard to copy. "We think the ink's multiple security features may be useful for antifraud applications," says Bai, "however we think the technology could be more useful for fabricating multiple functional sensor arrays, which we are now working towards."

HYREL 3-D had a display Timothy spotted at last month's Maker Faire Atlanta. They're not trying to hustle Kickstarter donors; they exceeded their $50,000 goal by over $100,000. Their main pitch was (and still is) that they are making high-reliability 3-D printers that can run many hours without breaking. Project spokesperson Daniel Hutchison says he and other people he knows who were making prototypes and short-run parts in the Atlanta area were continually disappointed by the poor reliability of available 3-D printers, which is why they decided to make their own. Open Source? Somewhat, partially, kind of... but they have a bunch of proprietary secret sauce in their software, too. Daniel goes into this in more detail in the video, so there's no need for us to repeat his words when you can hear them (or read them in the transcript) for yourself. (Alternate Video Link)

If you go to a sci-fi or gaming convention you'll see people in exotic "character" costumes, often holding exotic props, with some of the most popular being futuristic firearm mockups of one sort or another. Who makes all these cool fannish items? A whole bunch of artists and artisans, including Michelle Sleeper (who says she got tired of jokes about her name many years ago). She's not only one of these artisans, but is also a committed 3-D printer user, since 3-D printing is how she forms a high percentage of her props (with the word "props" being used here in the theatrical rather than the nautical sense). To keep up with what Michelle is making, you should check her blog. One of her most interesting posts, titled Atlanta Mini Maker Faire: On missing deadlines, failure, and triage, is about preparing for the event where Timothy Lord met and interviewed Michelle.

Even if gamer gatherings and SF conventions aren't your thing, the interview (along with the links above) gives a nice glimpse into the life of an independent artisan who uses technology to create a lot of her art. (Alternate Video Link)

theodp writes With an 11.6" screen, Windows 8.1, and free Office 365 for a year, the $199.99 solid-state HP Stream 11 laptop is positioned to make people think twice about Chromebooks (add $30 for the HP Stream 13). But will it? "The HP Stream 11 is clearly both inexpensive and a great value," writes Paul Thurrott. "At just $200, it's cheap, of course. But it also features a solid-feeling construction, a bright and fun form factor, a surprisingly high-quality typing experience and a wonderful screen. This isn't a bargain bin throwaway. The Stream 11 is something special." The HP Stream Family also includes the HP Stream 7, a $99.99 Windows 8.1 Tablet that includes the Office 365 deal. By the way, at the other end of the price spectrum, HP has introduced the Sprout, which Fast Company calls a bold and weird PC that's bursting at the seams with new ideas, from 3-D scanning to augmented reality. (We mentioned the Sprout a few days ago, too; HP seems to be making some interesting moves lately, looks like they're getting on the smartwatch bandwagon, too.) If you're looking at the Stream as a cheap platform for OSes other than Windows, be cautious: one of the reviews at the Amazon page linked describes trouble getting recent Linux distributions to install.

Lucas123 writes HP today announced an 3D industrial printer that it said will be half the cost of current additive manufacturing systems while also 10 times faster, enabling production parts to be built. The company also announced Sprout, a new immersive computing platform that combines a 23-in touch screen monitor and horizontal capacitive touch mat with a scanner, depth sensor, hi-res camera, and projector in a single desktop device. HP's Multi Jet Fusion printer will be offered to beta customers early next year and is expected to be generally available in 2016. The machine uses a print bar with 30,000 nozzles spraying 350 million drops a second of thermoplastic or other materials onto a print platform. The Multi Jet Fusion printer uses fused deposition modeling, an additive manufacturing technology first invented in 1990. the printer works by first laying down a layer of powder material across a build area. Then a fusing agent is selectively applied with the page-wide print bar. Then the same print bar applies a detailing agent at the parts edge to give high definition. The material is then exposed to an energy source that fuses it.

Lucas123 writes XYZPrinting today released the first 3D printer with embedded scanner that has the ability to replicate objects between 2-in and 6-in in size and print objects of up to 7.8-in square from .stl files. The printer's retailing for $799. A review of the new da Vinci 1.0 AiO all-in-one 3D printer revealed the 3D scanning capability, which is supposed to have a .05mm resolution, captures overall size and some finer features of an object but it falls short when it comes to precise details; thin protrusions and through-object holes are often missed in a scan. The mechanics — the printing head, two laser scanning/camera pods and turntable, and the motorized print table — are fully enclosed in a sleek-looking blue and white cubical case with a large transparent, hinged-front door. The front of the printer has a simple push button keypad for traversing a menu on a 2.6-in LCD black-and-white display. The printer is about 18-in. x 20-in. x 22-in. in size and weighs 60.6 lbs. While this is a desktop printer, it takes up a sizeable amount of room on your desk. It can print with either ABS or PLA thermopolymer.

jfruh writes: Japan has some of the strictest anti-gun laws in the world, and the authorities there aim to make sure new technologies don't open any loopholes. 28-year-old engineer Yoshitomo Imura has been sentenced to two years in jail after making guns with a 3D printer in his home in Kawasaki.

kthreadd writes: 15 years after the release of CUPS 1.0, Apple has now released version 2.0 of the printing system for GNU/Linux and other Unix-style operating systems. One of the major new features in 2.0 is that the test program for ippserver now passes the IPP Everywhere self-certification tests. Also, they've made an interesting blog post looking at the past and future of printing. Since the first major release in 1999, printing has become much more personal. Printer drivers are going away, and mobile usage is now the norm."

mrspoonsi writes Hewlett-Packard is planning to split itself into two separate businesses, The Wall Street Journal is reporting. Sources tell the WSJ that HP will split its personal-computer and printer segments from its corporate hardware and services business. The announcement could come as early as Monday, the sources said. The company reorganized itself in 2012 under CEO Meg Whitman. That move combined its computer and printer businesses. The PC and computer segment is massive for HP. For the first six months this year, it reported $27.8 billion in revenue. That's about three times the size of HP's next biggest unit, the Enterprise Group, which makes servers, storage, and network hardware. Under the new split, Whitman would be chairman of the computer and printer business, and CEO of a separate Enterprise Group, according to one of the sources. Patricia Russo, who sits on HP's board, would be chairman of the enterprise company. The printer and PC operation would be led by Dion Weisler, a current exec in that division.

electronic convict writes: A year ago, security researcher Marc Rogers demonstrated how to spoof the TouchID sensor in the iPhone 5S using some Elmer's glue and glycerol — oh, and a high resolution camera and a laser printer. Has TouchID security improved at all on the iPhone 6? Not really, Rogers reports in his latest post, in which he again hacks the iPhone 6's TouchID sensors using the same method as before. "Fake fingerprints created using my previous technique were able to readily fool both devices [the 6 and the 5S]," he reports. Rogers, however, says there's no reason to panic, as the attack requires substantial skill, patience and a good clear fingerprint. As he writes: "We use locks on our doors to keep criminals out not because they are perfect, but because they are both convenient and effective enough to meet most traditional threats."

mpicpp writes with news that UPS will be expanding their 3D printing services. UPS announced plans Monday to bring in-store 3-D-printing services to nearly 100 stores across the country, billing itself as the first national retailer to do so. With the UPS system, customers can submit their own designs for objects like product prototypes, engineering parts and architectural models that are then printed on a professional-quality 3-D printer made by Stratasys. Prices vary depending on the complexity of the object; an iPhone case would be about $60, while a replica femur bone would be around $325. UPS can also connect customers with outside professionals who charge an hourly rate to help produce a design file for the printer. It generally takes about four or five hours to print a simple object, with more complex items taking a day or more. The program started as a pilot at six locations last year, and UPS says those stores "saw demand for 3-D print continuing to increase across a broad spectrum of customers."

A "flawless" launch early Sunday from Cape Canaveral has sent a load of supplies on its way to the International Space Station aboard a Falcon 9-lofted SpaceX Dragon capsule. Food, care packages and provisions for NASA's astronauts make up more than a third of the cargo onboard Dragon. But the spacecraft also has experiments and equipment that will eventually help scientists complete 255 research projects in total, according to NASA. In Dragon's trunk, there's an instrument dubbed RapidScat, which will be installed outside the space station to measure the speed and direction of ocean winds on Earth. Among the commercially funded experiments onboard Dragon is a materials-science test from the sports company Cobra Puma Golf designed to build a stronger golf club. Dragon is also hauling the first space-grade 3D printer, built by Made in Space, which will test whether the on-the-spot manufacturing technology is viable without gravity.

Lucas123 writes Power tool maker Dremel today announced it's now selling a desktop 3D printer that it said is targeted at "the masses" with a $1,000 price tag and intuitive software. Dremel's 3D Idea Builder is a fused deposition modeling (FDM) machine that can use only one type of polymer filament, polylactide (PLA) and that comes in 10 colors. The new 3D printer has a 9-in. x 5.9-in. x 5.5-in. build area housed in a self-contained box with a detachable lid and side panels. Dremel's currently selling its machine on Amazon and The Home Depot's website, but it plans brick and mortar store sales this November.

University of Arizona grad student Matt Bunting doesn't come across as a mad scientist. That's a very good thing, because his robot hexapod creations are easy to imagine crawling across the USA in large hordes, devouring everything in their path and using all the electricity they come across to feed their Queen Hexapod, a 3-D printer mounted on a hexapod chassis that turns everything fed to it into more robots. Luckily, the real life Matt is an affable (self-described) "Roboticist, Electrical Engineer, Musician, and Rock Crawler" who freely admits that at this time his robotic creations have no practical application whatsoever. This is probably true, except for the fact that they can liven up a music video like mad, as you can see on YouTube in Pedals Music Video (featuring REAL robots) . Our little video is a lot simpler, of course. In it, we interview Matt and he tells us what he's up to with his robots, and gives some 'how to get started with robotics' advice for budding young engineers. (Alternate Video Link)

wiredog writes Security researcher Michael Jordon has hacked a Canon's Pixma printer to run Doom. He did so by reverse engineering the firmware encryption and uploading via the update interface. From the BBC: "Like many modern printers, Canon's Pixma range can be accessed via the net, so owners can check the device's status. However, Mr Jordon, who works for Context Information Security, found Canon had done a poor job of securing this method of interrogating the device. 'The web interface has no user name or password on it,' he said. That meant anyone could look at the status of any device once they found it, he said. A check via the Shodan search engine suggests there are thousands of potentially vulnerable Pixma printers already discoverable online. There is no evidence that anyone is attacking printers via the route Mr Jordon found."

pacopico writes Intellectual Ventures, the world's most infamous patent troll, has changed its tune — maybe. According to a story in Businessweek, the company has started turning a number of its ideas into products, ranging from hydration sensors to waterless washing machines and self-healing concrete. The story reveals some new tidbits about IV, including that it pays inventors $17,000 per idea, has a new start-up fund and that one of its cofounders got tossed out of school for hacking. IV is obvisouly trying to improve its reputation, but plenty of skeptics remain who think this is just a ruse meant to draw attention away from its patent lawsuits.

mrspoonsi sends this news from the BBC: Fuji Xerox has developed a new robotic printer that can move around a lounge or office to bring documents to the person who printed them. The printer is designed to be used primarily in public places as a way to keep sensitive documents secure. Sensors on the machine prevent it from bumping into people on the way. However, some analysts argued that the idea was not cost effective when compared with other secure printing methods. Fuji Xerox — a joint venture between the two firms — has been testing the printer this month at a business lounge in Tokyo. Each desk in the lounge is given a unique web address from which to print. Users access the address and upload documents to be printed. Once the printer receives the job, it moves to the intended recipient who then has to display a smart card to activate printing.
