3D Printing Doubles the Strength of Stainless Steel (sciencemag.org) 96

sciencehabit writes: Researchers have come up with a way to 3D print tough and flexible stainless steel, an advance that could lead to faster and cheaper ways to make everything from rocket engines to parts for nuclear reactors and oil rigs. The team designed a computer-controlled process to not only create dense stainless steel layers, but to more tightly control the structure of their material from the nanoscale to micron scale. That allows the printer to build in tiny cell wall-like structures on each scale that prevent fractures and other common problems. Tests showed that under certain conditions the final 3D printed stainless steels were up to three times stronger than steels made by conventional techniques and yet still ductile.
The work was done using a commercially-available 3D printer, according to Science magazine. "That makes it likely that other groups will be able to quickly follow their lead to make a wide array of high-strength stainless steel parts for everything from fuel tanks in airplanes to pressure tubes in nuclear power plants."

The International Space Station Is Getting Its First Printer Upgrade in 17 Years (mashable.com) 174

Lance Ulanoff, writing for Mashable: Somewhere, 254 miles above us, an astronaut is probably printing something. Ever since the International Space Station (ISS) welcomed its first residents in November of 2000, there have been printers on board. Astronauts use them to print out critical mission information, emergency evacuation procedures and, sometimes, photos from home. According to NASA, they print roughly 1,000 pages a month on two printers; one is installed on the U.S. side of the ISS, the other in the Russian segment. ISS residents do all this on 20-year-old technology. "When the printer was new, it was like 2000-era tech and we had 2000-era laptop computers. Everything worked pretty good," recalled NASA Astronaut Don Pettit, who brought the first printer up to the ISS. But "the printer's been problematic for the last five or six years," said Pettit who's spent a total of one year on the station. It's not that the Space Station has been orbiting with the same printer since Justin Timberlake was still N'Sync. NASA had dozens of this printer and, as one failed, they'd send up another identical model. But now it's time for something truly new. In 2018, NASA will send two brand new, specialized printers up to the station. However, figuring out the right kind of printer to send was a lot more complicated than you'd probably expect. NASA has turned to HP for its IT supply and needs. The agency requires the following things in its printer: print and handle paper management in zero gravity, handle ink waste during printing, be flame retardant, and be power efficient. HP, Mashable reports, has recommended the HP Envy 5600, its all-in-one (printer, scanner, copier, fax) device that retails for $129.99. The model has been modified, according to the report.

MakerBot Launches New 'MakerBot Labs' Platform (hackaday.com) 42

"MakerBot just announced a new Open Source initiative called 'MakerBot Labs'," writes Slashdot reader szczys. "It is a small move, centering around some new APIs and a new extruder which is listed as experimental and not covered by their normal warranty. Largely they missed the mark on making a meaningful move toward openness, but with a new CEO at the helm as of January this could be the first change of the rudder in a larger effort to turn the ship around."

Makerbot's history is "an example of how you absolutely should not operate an open source company," argues Hackaday, saying it's left them skeptical of Makerbot's latest move: It reads like a company making a last ditch effort to win back the users they were so sure they didn't need just a few years ago... The wheels of progress turn slowly in any large organization, and perhaps doubly so in one that has gone through so much turmoil in a relatively short amount of time. It could be that it's taken Goshen these last nine months to start crafting a plan to get MakerBot back into the community's good graces.
From MakerBot's press release: "After setting high industry standards for what makes a quality and reliable 3D printing experience, we're introducing this new, more open platform as a direct response to our advanced users calling for greater freedom with materials and software."

New Open Source 3D Printer Can Print Without Human Intervention (autodrop3d.com) 49

Slashdot reader mmiscool shares some videos about "the next step in 3D printing": Autodrop3d is an open source system that solves the problem of needing a human to remove a 3D print from its print bed. Implemented as an open source hardware and software system, it allows for web based, multi-user print queue, automatic notifications, and web-based CAD design tools to all be integrated in one open source system. There's a video that shows the hardware in operation and a link to the web site with a Git repository for the software and hardware components.
Autodrop3D is now raising money on Kickstarter, promising to show their support for open source innovation by "releasing all of our documentation, design files, and software prior to the end of this Kickstarter campaign."

And for $75 pledges, "we will 3D print an object of your choice and mail it to you.... You will also receive our heartfelt thanks."

Hundreds of Printers Expose Backend Panels and Password Reset Functions Online (bleepingcomputer.com) 61

Catalin Cimpanu, writing for BleepingComputer: A security researcher has found nearly 700 Brother printers left exposed online, allowing access to the password reset function to anyone who knows what to look for. Discovered by Ankit Anubhav, Principal Researcher at NewSky Security, the printers offer full access to their administration panel over the Internet. Anubhav has provided Bleeping Computer with a list of exposed printers. Accessing a few random URLs, Bleeping has discovered a wide range of Brother printer models, such as DCP-9020CDW, MFC-9340CDW, MFC-L2700DW, or MFC-J2510, just to name a few. The cause of all these exposures is Brother's choice of shipping the printers with no admin password. Most organizations most likely connected the printers to their networks without realizing the admin panel was present and wide open to connections. These printers are now easy discoverable via IoT search engines like Shodan or Censys.

Hobbyist Gives iPhone 7 the Headphone Jack We've Always Wanted (engadget.com) 194

intellitech shares a report from Engadget: For those of you who miss the iPhone headphone jack, you're definitely not alone. But Strange Parts creator Scotty Allen missed it so much that he decided to add one to his iPhone 7. He just posted a video of the project's entire saga, with all of its many ups and downs, and in the end he holds what he set out to create -- a current generation iPhone with a fully functional headphone jack. It turns out, real courage is adding the headphone jack back to the iPhone. The project took around 17 weeks to complete and throughout it Allen spent thousands of dollars on parts including multiple iPhones and screens and handfuls of lightning to headphone adaptors. Along the way, Allen bought a printer, a nice microscope and fancy tweezers. He had to design his own circuit boards, have a company manufacture multiple iterations of flexible circuit boards and at one point early on had to consult with a chip dealer that a friend hooked him up with.

The final product works by using a lightning to headphone adaptor that's incorporated into the internal structure of the phone. However, because the headphone jack is powered via the phone's lightning jack with a circuit board switching between the two depending on whether headphones or a charger are plugged into the phone, you can't actually listen to music and charge the phone at the same time.

The US Government Wants To Permanently Legalize the Right To Repair (vice.com) 153

An anonymous reader quotes a report from Motherboard: In one of the biggest wins for the right to repair movement yet, the U.S. Copyright Office suggested Thursday that the U.S. government should take actions to make it legal to repair anything you own, forever -- even if it requires hacking into the product's software. Manufacturers -- including John Deere, Ford, various printer companies, and a host of consumer electronics companies -- have argued that it should be illegal to bypass the software locks that they put into their products, claiming that such circumvention violated copyright law. Thursday, the U.S. Copyright Office said it's tired of having to deal with the same issues every three years; it should be legal to repair the things you buy -- everything you buy -- forever. "The growing demand for relief under section 1201 has coincided with a general understanding that bona fide repair and maintenance activities are typically non infringing," the report stated. "Repair activities are often protected from infringement claims by multiple copyright law provisions." "The Office recommends against limiting an exemption to specific technologies or devices, such as motor vehicles, as any statutory language would likely be soon outpaced by technology," it continued.

Top UK Supermarket Laser Prints Labels On Avocados To Reduce Waste (telegraph.co.uk) 219

One of the largest British retailers in London, M&S, is opting in for laser-printed barcodes to reduce paper waste. "The labels, which are etched onto fruit's skins with lasers instead of stickers, will save 10 tons of paper and five tons of glue every year according to M&S," reports The Telegraph. The labels will be etched into the skins of avocados, but "could soon be introduced to other fruit and vegetables and adopted by other supermarkets which are looking for new waste reduction techniques." The labels themselves include the shop logo, best before date, country of origin and product code for entering at the till. What's more is that the avocado's skin is the only area impacted by the lasers -- none of the fruit gets damaged. Bruce66423 writes: Print the information usually on the packaging to reduce waste. Excellent idea -- although the Aldi (the radically cheap, all own brand chain) alternative is to leave avocados untouched and get the cashiers to enter the code.

Researcher Wants To Protect Whistleblowers Against Hidden Printer Dots (bleepingcomputer.com) 218

An anonymous reader writes: "Gabor Szathmari, a security researcher for CryptoAUSTRALIA, is working on a method of improving the security of leaked documents by removing hidden dots left behind by laser printers, which are usually used to watermark documents and track down leakers," reports Bleeping Computer. "Szathmari's work was inspired by the case of a 25-year-old woman, Reality Leigh Winner, who was recently charged with leaking top-secret NSA documents to a news outlet." According to several researchers, Winner might have been caught after The Intercept had shared some of the leaked documents with the NSA. These documents had the invisible markings left behind by laser printers, which included the printer's serial number and the date and time when the document was printed. This allowed the NSA to track down Winner and arrest her even before she was able to publish the leaked documents. Now, Szatmari has submitted a pull request to the PDF Redact Tools, a project for securely redacting and stripping metadata from documents before publishing. Szathmari's pull request adds a code routine to the PDF Redact Tools project that would allow app operators to convert documents to black and white before publishing. "The black and white conversion will convert colors like the faded yellow dots to white," Szathmari said in an interview. Ironically, the project is managed by First Look Media, the parent company behind The Intercept news outlet.

How a Few Yellow Dots Burned the Intercept's NSA Leaker (arstechnica.com) 308

On Monday, news outlet The Intercept released documents on election tampering from an NSA leaker. The documents revealed that a Russian intelligence operation sent spear-phishing emails to more than 100 local election officials days before the election, which ran through a hack of a U.S. voting software supplier. Hours later, the Department of Justice charged 25-year-old government contractor Reality Leigh Winner with sharing top secret material with the media. The DoJ said it Winner had "printed and improperly removed classified intelligence reporting, which contained classified national defense information" before mailing the materials. But how could the DoJ know that it was Winner who had printed the documents, or that the documents were printed at all? ArsTechnica explains: [...] The Intercept team inadvertently exposed its source because the copy showed fold marks that indicated it had been printed -- and it included encoded watermarking that revealed exactly when it had been printed and on what printer. The watermarks in the scanned document The Intercept published yesterday -- were from a Xerox Docucolor printer. Many printers use this or similar schemes, printing faint yellow dots in a grid pattern on printed documents as a form of steganography, encoding metadata about the document into its hard-copy output. Researchers working with the Electronic Frontier Foundation have reverse-engineered the grid pattern employed by this class of printer; using the tool, Ars (and others, including security researcher Robert Graham) determined that the document passed to The Intercept was printed on May 9, 2017 at 6:20am from a printer with the serial number 535218 or 29535218.

US Supreme Court Protects Consumers' Right To Refill Ink Cartridges In Precedent-Setting Lexmark vs Impression Case (hothardware.com) 259

The U.S. Supreme Court said on Tuesday companies give up their patent rights when they sell an item, in a ruling that puts new limits on businesses' ability to prevent their products from being resold at a discount. The ruling is a defeat for Lexmark International, which was trying to stop refurbished versions of its printer cartridges from undercutting its U.S. sales. It's also a blow to companies like HP and Canon that sell their printers for a relatively low cost with the idea that they will recoup money on sales of replacement cartridges. From a report: Lexmark originally set its sights on Impression Products, a small company that specializes in remanufacturing print cartridges for resale at prices much lower than what a customer would pay for a "genuine" Lexmark product. These cartridges often have no noticeable difference in performance compared to genuine ink or toner cartridges -- the only real difference is that customers can save a lot of money by going the remanufactured route. This secondary market for cartridges not only has implications for regular Joes looking to save a buck, but also businesses that are always looking to cut costs.

Apple Is Lobbying Against Your Right To Repair iPhones, New York State Records Confirm (vice.com) 235

An anonymous reader quotes a report from Motherboard: Lobbying records in New York state show that Apple, Verizon, and the tech industry's largest trade organizations are opposing a bill that would make it easier for consumers and independent companies to repair your electronics. The bill, called the "Fair Repair Act," would require electronics companies to sell replacement parts and tools to the general public, would prohibit "software locks" that restrict repairs, and in many cases would require companies to make repair guides available to the public. Apple and other tech giants have been suspected of opposing the legislation in many of the 11 states where similar bills have been introduced, but New York's robust lobbying disclosure laws have made information about which companies are hiring lobbyists and what bills they're spending money on public record. According to New York State's Joint Commission on Public Ethics, Apple, Verizon, Toyota, the printer company Lexmark, heavy machinery company Caterpillar, phone insurance company Asurion, and medical device company Medtronic have spent money lobbying against the Fair Repair Act this year. The Consumer Technology Association, which represents thousands of electronics manufacturers, is also lobbying against the bill. The records show that companies and organizations lobbying against right to repair legislation spent $366,634 to retain lobbyists in the state between January and April of this year. Thus far, the Digital Right to Repair Coalition -- which is generally made up of independent repair shops with several employees -- is the only organization publicly lobbying for the legislation. It has spent $5,042 on the effort, according to the records.

Scientists 3D-Print Ovaries To Allow Infertile Mice To Mate and Give Birth (theguardian.com) 64

An anonymous reader quotes a report from The Guardian: Infertile mice have given birth to healthy pups after having their fertility restored with ovary implants made with a 3D printer. Researchers created the synthetic ovaries by printing porous scaffolds from a gelatin ink and filling them with follicles, the tiny, fluid-holding sacs that contain immature egg cells. In tests on mice that had one ovary surgically removed, scientists found that the implants hooked up to the blood supply within a week and went on to release eggs naturally through the pores built into the gelatin structures. The work marks a step towards making artificial ovaries for young women whose reproductive systems have been damaged by cancer treatments, leaving them infertile or with hormone imbalances that require them to take regular hormone-boosting drugs. Of seven mice that mated after receiving the artificial ovaries, three gave birth to pups that had developed from eggs released by the implants. The mice fed normally on their mother's milk and went on to have healthy litters of their own later in life. Writing in the journal Nature Communications, the scientists describe how they printed layered lattices of gelatin strips to make the ovary implants. The sizes and positions of the holes in the structures were carefully controlled to hold dozens of follicles and allow blood vessels to connect to the implants. Mature eggs were then released from the implants as happens in normal ovulation.

Researchers Devise New Printing Technique To Produce High-Resolution Color Images Without Using Ink (gizmodo.com) 55

An anonymous reader writes: Researchers at the Technical University of Denmark have taken inspiration from creatures like butterflies and peacocks, whose wings and feathers create bright, iridescent colors not through light-absorbing pigments, but by bending and scattering light at the molecular level, creating what's known as structural color. The new printing method the team has developed starts with sheets of plastic covered in thousands of microscopic pillars spaced roughly 200 nanometers apart. To get those tiny plastic pillars to produce color, or at least appear to, they're first covered with a thin layer of germanium -- a shiny, grayish-white metalloid material. An ultra-fine laser blasts the germanium until it melts onto each pillar, strategically changing their shape and thickness (Editor's note: original research paper). This is then followed by a protective coating that helps preserves the shape and structure of all those tiny pillars. When light hits this modified plastic surface, the lightwaves bounce around amongst the various pillars, which end up changing their wavelength as they're reflected, producing different colors. The researchers were able to predict what colors would be produced by those nanoscale pillars, and by creating specific patterns, they were able to generate recognizable, high-contrast images.

Boeing Expects To Save Millions In Dreamliner Costs Using 3D-Printed Titanium Parts (reuters.com) 73

According to Reuters, Boeing has hired Norsk Titanium AS to print titanium parts for its 787 Dreamliner, paving the way to cost savings of $2 million to $3 million for each plane. The 3D-printed metal parts will replace pieces made with more expensive traditional manufacturing, thus making the 787 more profitable. From the report: Strong, lightweight titanium alloy is seven times more costly than aluminum, and accounts for about $17 million of the cost of a $265 million Dreamliner, industry sources say. Boeing has been trying to reduce titanium costs on the 787, which requires more of the metal than other models because of its carbon-fiber composite fuselage and wings. Titanium also is used extensively on Airbus Group SE's rival A350 jet. Norsk worked with Boeing for more than a year to design four 787 parts and obtain Federal Aviation Administration certification for them, Chip Yates, Norsk Titanium's vice president of marketing, said. Norsk expects the U.S. regulatory agency will approve the material properties and production process for the parts later this year, which would "open up the floodgates" and allow Norsk to print thousands of different parts for each Dreamliner, without each part requiring separate FAA approval, Yates said. Norsk said that initially it will print in Norway, but is building up a 67,000-square-foot (6,220-square-meter) facility in Plattsburgh in upstate New York, where it aims to have nine printers running by year-end.

New 'Spray-On' Memory Could Turn Everyday Items Into Digital Storage Devices (duke.edu) 38

Researchers at Duke University have developed "spray-on" digital memory using only an aerosol jet printer and nanoparticle inks. An anonymous reader quotes Duke Today: The device, which is analogous to a 4-bit flash drive, is the first fully-printed digital memory that would be suitable for practical use in simple electronics such as environmental sensors or RFID tags. And because it is jet-printed at relatively low temperatures, it could be used to build programmable electronic devices on bendable materials like paper, plastic or fabric...

The new material, made of silica-coated copper nanowires encased in a polymer matrix, encodes information not in states of charge but instead in states of resistance. By applying a small voltage, it can be switched between a state of high resistance, which stops electric current, and a state of low resistance, which allows current to flow. And, unlike silicon, the nanowires and the polymer can be dissolved in methanol, creating a liquid that can be sprayed through the nozzle of a printer.

Amazingly, its write speed is three microseconds, "rivaling the speed of flash drives." The information can be re-written many times, and the stored data can last for up to 10 years.

How the IBM 1403 Printer Hammered Out 1,100 Lines Per Minute (ieee.org) 174

schwit1 quotes a report from IEEE Spectrum: The IBM 1460, which went on sale in 1963, was an upgrade of the 1401 [which was one of the first transistorized computers ever sold commercially]. Twice as fast, with a 6-microsecond cycle time, it came with a high-speed 1403 Model 3 line printer. The 1403 printer was incredibly fast. It had five identical sets of 48 embossed metal characters like the kind you'd find on a typewriter, all connected together on a horizontal chain loop that revolved at 5.2 meters per second behind the face of a continuous ream of paper. Between the paper and the character chain was a strip of ink tape, again just like a typewriter's. But rather than pressing the character to the paper through the ink tape, the 1403 did it backward, pressing the paper against the high-speed character chain through the ink tape with the aid of tiny hammers. Over the years, IBM came out with eight models of the 1403. Some versions had 132 hammers, one for each printable column, and each was individually actuated with an electromagnet. When a character on the character chain aligned with a column that was supposed to contain that character, the electromagnetic hammer for that column would actuate, pounding the paper through the ink tape and into the character in 11 microseconds. With all 132 hammers actuating and the chain blasting along, the 1403 was stupendously noisy [...] The Model 3, which replaced the character chain with slugs sliding in a track driven by gears, took just 55 milliseconds to print a single line. When printing a subset of characters, its speed rose from 1,100 lines per minute to 1,400 lines per minute.

Rogue System Administrator Faces 10 Years In Prison For Shutting Down Servers, Deleting Core Files On the Day He Was Fired (techspot.com) 237

Joe Venzor, a former employee at boot manufacturer Lucchese, had a near total meltdown after he got fired from his IT system administrator position. According to TechSpot, he shut down the company's email and application servers and deleted the core system files. Venzor now faces up to 10 years in prison and a $250,000 fine. From the report: Venzor was let go from his position at the company's help desk and immediately turned volatile. He left the building at 10:30AM and by 11:30, the company's email and application servers had been shut down. Because of this, all activities ground to a halt at the factory and employees had to be sent home. When the remaining IT staff tried to restart them, they discovered the core system files had been deleted and their account permissions had been demoted. Eventually the company was forced to hire a contractor to clean up all of the damage, but this resulted in weeks of backlog and lost orders. While recovering from the attack was difficult, finding out who did it was simple. Venzor was clearly the prime suspect given the timing of the incident, so they checked his account history. They discovered he had collected usernames and passwords of his IT colleagues, created a backdoor account disguised as an office printer, and used that account from his official work computer.

Why You Should Care About the Supreme Court Case On Toner Cartridges (consumerist.com) 227

rmdingler quotes a report from Consumerist: A corporate squabble over printer toner cartridges doesn't sound particularly glamorous, and the phrase "patent exhaustion" is probably already causing your eyes to glaze over. However, these otherwise boring topics are the crux of a Supreme Court case that will answer a question with far-reaching impact for all consumers: Can a company that sold you something use its patent on that product to control how you choose to use after you buy it? The case in question is Impression Products, Inc v Lexmark International, Inc, came before the nation's highest court on Tuesday. Here's the background: Lexmark makes printers. Printers need toner in order to print, and Lexmark also happens to sell toner. Then there's Impression Products, a third-party company makes and refills toner cartridges for use in printers, including Lexmark's. Lexmark, however, doesn't want that; if you use third-party toner cartridges, that's money that Lexmark doesn't make. So it sued, which brings us to the legal chain that ended up at the Supreme Court. In an effort to keep others from getting a piece of that sweet toner revenue, Lexmark turned to its patents: The company began selling printer cartridges with a notice on the package forbidding reuse or transfer to third parties. Then, when a third-party -- like Impression -- came around reselling or recycling the cartridges, Lexmark could accuse them of patent infringement. So far the courts have sided with Lexmark, ruling that Impression was using Lexmark's patented technology in an unauthorized way. The Supreme Court is Impression's last avenue of appeal. The question before the Supreme Court isn't one of "can Lexmark patent this?" Because Lexmark can, and has. The question is, rather: Can patent exhaustion still be a thing, or does the original manufacturer get to keep having the final say in what you and others can do with the product? Kate Cox notes via Consumerist that the Supreme Court ruling is still likely months away. However, she has provided a link to the transcript of this week's oral arguments (PDF) in her report and has dissected it to see which way the justices are leaning on the issue.
