Heffenfeffer writes: Russian company Apis Cor has manufactured a 3D printed concrete house on-site in 24 hours in Stupino Town, Russia. Using a tower crane-shaped concrete extruder that can rotate 360 degrees, the 38 square meter (408.88 square foot) rotor-shaped home walls were constructed in one day. Voids left in the manufacturing process were filled by hand, installing windows, doors, and adding polyurethane and fiber insulation to the hollow concrete walls. The roof was also constructed by hand using polymer membranes, welded together using hot air and special equipment. Total construction costs were $10,134 (USD), approximately $266.66 per square meter ($24.78 per square foot). They also constructed a temporary protective heated tent to surround the house as they constructed the house during winter. Though the printer can be used at temperatures down to -35C, concrete has to be at least +5C to cure. Further reading: Designboom Magazine

An anonymous reader shares a ZDNet report: George Brasher is a 26-year HP veteran who has worked in a variety of roles in the company's printer and PC divisions over the years and is now HP Inc's managing director for the UK and Ireland. We began by asking how the first fifteen 'post-split' months had gone. "If you go back to the genesis of the separation, what Meg [Whitman, CEO of HPE and chairwoman of HP Inc] said was that, by splitting into two businesses, we'd be able to have more focus -- and I think that's truly what's happened with HP Inc. What we wanted to get out of it was: could we be more focused on our markets; could we actually accelerate our pace of innovation and get closer to our customers? In general, I'd say the answer is a resounding 'yes'." [...] The second thing is -- and you can see examples around this room [the CWC] -- we're a technology company, and innovation is our lifeblood: if you look at PC and print, we've seen more significant high-quality introductions in the last 15 months than in any previous 15-month period." [...] "The proof is always in the pudding: I look at the Spectre x360, the Elite X3 and other devices -- and it's not just new devices, but also the quality of the new devices; being able to have a partnership with B&O and thinking about a new computing experience. On the print side, it's the same thing: in September we announced our single biggest rollout ever, with a set of 16 A3 multifunction devices starting in a couple of months and rolling out over the course of the year. I don't think that happens unless you have separation, because then you've got a management team and a board, and a group of employees, that are just laser-focused on driving against that."

T.L. Stanley, writing for AdWeek: It's a fine line between effective '80s homage and clumsy retro spoof, with the latter usually involving a lot of overplayed visual gags like brick-sized cell phones and VHS tapes. Cue pointing and laughing. This new HP video, dubbed "Computer Show," hits the sweet spot perfectly with its recreation of a Reagan-era public access show about technology, but with a fish-out-of-water spin. The host is stuck in time -- stilted stage manner, goofy haircut and all -- but his guests are current-day tech pioneers. Awkward hilarity ensues. The short film, made by Giant Spoon and Sandwich Video for HP, sets up a print-off between HP's PageWide super-fast model and a dot matrix supplied by an employee of the neighborhood "Kwikopy."

Last year an attacker forced thousands of unsecured printers to spew racist and anti-semitic messages. But this year's attack is even bigger. An anonymous reader writes: A grey-hat hacker going by the name of Stackoverflowin has pwned over 150,000 printers that have been left accessible online. For the past 24 hours, Stackoverflowin has been running an automated script that searches for open printer ports and sends a rogue print job to the target's device. The script targets IPP (Internet Printing Protocol) ports, LPD (Line Printer Daemon) ports, and port 9100 left open to external connections. From high-end multi-functional printers at corporate headquarters to lowly receipt printers in small town restaurants, all have been affected. The list includes brands such as Afico, Brother, Canon, Epson, HP, Lexmark, Konica Minolta, Oki, and Samsung.

The printed out message included recommendations for printer owners to secure their device. The hacker said that people who reached out were very nice and thanked him.
The printers apparently spew out an ASCII drawing of a robot, along with the words "stackoverflowin the hacker god has returned. your printer is part of a flaming botnet... For the love of God, please close this port." The messages sometimes also include a link to a Twitter feed named LMAOstack.

Kickstarter has suspended a crowdfunding campaign that promised its backers "a high-end multi-material 3D liquid jet printer" that could print circuit boards. Slashdot reader PrintBetter writes: With just three days to go, backers were pulling out of Next Dynamics' NexD1 Kickstarter amidst fears the creator exaggerated progress on their prototype and tried to pass off prints purchased from Shapeways as their own... [T]he Berlin company's campaign was a darling of Kickstarter, carrying their "Projects We Love" endorsement and receiving praise from publications like TechCrunch, 3DPrint.com and Make magazine for its purported ability to mix up to six plastic and conductive resins in a single print.

But as pledges grew to over half a million euros, backers started to sense things didn't add up. Kevin Holmes commented "Wow, I'm stunned -- I cancelled my pledge already ... Did they really buy parts from Shapeways and pass them off as their own?" while Anthony Webb remarked "I've backed over 100 projects on Kickstarter ... but this one takes the cake for a complete scam." The company was a no-show at events it scheduled this week, including a demonstration Monday and a live stream Tuesday.

New submitter drunkdrone quotes a report from International Business Times: Spanish scientists say they have developed a prototype 3D printer that is capable of printing "functional" human skin that can be used for transplant patients, as well as an ethical alternative to animal testing. The so-called bioprinter uses special "ink" consisting of human cells and other biological components to reproduce the natural structure of the skin, including the external epidermis and the deeper dermis layer. These "bio inks" are deposited from special injectors onto a print bed to produce skin that is bioactive and capable of producing its own human collagen, the researchers claim. This means that the 3D-printed skin is, in essence, living tissue, making it suitable for treating burn patients and for testing cosmetic, chemical and pharmaceutical products. According to UC3M, the technology could be used to print other human tissues, although first it needs to be approved by regulators in order to ensure the skin it produces is fit for use on human patients.

A team of MIT researchers have created the world's strongest and lightest material known to man using graphene. Futurism reports: Graphene, which was heretofore, the strongest material known to man, is made from an extremely thin sheet of carbon atoms arranged in two dimensions. But there's one drawback: while notable for its thinness and unique electrical properties, it's very difficult to create useful, three-dimensional materials out of graphene. Now, a team of MIT researchers discovered that taking small flakes of graphene and fusing them following a mesh-like structure not only retains the material's strength, but the graphene also remains porous. Based on experiments conducted on 3D printed models, researchers have determined that this new material, with its distinct geometry, is actually stronger than graphene -- making it 10 times stronger than steel, with only five percent of its density. The discovery of a material that is extremely strong but exceptionally lightweight will have numerous applications. As MIT reports: "The new findings show that the crucial aspect of the new 3-D forms has more to do with their unusual geometrical configuration than with the material itself, which suggests that similar strong, lightweight materials could be made from a variety of materials by creating similar geometric features."

schwit1 writes: A team at Stony Brook Children's Hospital was able to use a 3-D printer to produce a replica of baby Vincent's skull, which, in turn, allowed the medical team to fully rehearse the surgery long before they stepped into the operating room. Through a collaboration with Medical Modeling in Colorado, known now as 3D Systems, Egnor and Duboys were able to virtually plan the entire surgery in advance. Duboys said images from a CT scan of baby Vincent's head were sent to the company, which then manufactured a model skull using the CT information as a template. The company also created a model of what Vincent's skull should look like after surgery.

When Google launched Cloud Print, it removed a lot of the hassle from using a printer. Instead of a printer only printing documents from the PC it was connected to, Cloud Print allowed any device, be it a Windows PC, Mac, Chromebook, smartphone, tablet, etc. to print to any printer either locally or remotely. However, Google Cloud Print has gone awry this week, as reports PCMag, and Epson printer owners are suffering because of it. From the article: A thread appeared on the Chromebook Central Help Forum explaining a problem where an Epson XP-410$185.00 at Amazon printer was turning itself off after 30 seconds. The printer worked without issue for two years, but now it wouldn't stay powered on. At first, this seems like a printer hardware problem, but the printer started working again once it was disconnected from the Internet. However, as soon as Google Print Cloud was enabled, the automatic power down happened again. Later in the support thread an Epson WF-4630 owner reports the same issue, as do XP-215, XP-415, XP-610, WF-545, WF-845, and WF-7610 owners.A change in Google's API for its cloud service triggered the issue, reports ArsTechnica. The change has caused a conflict between Cloud Print and printers' firmware.

Update: Epson has responded to Slashdot, pointing us to its support page that has instructions on how to fix the issue on many of Epson printers.

Security experts consider the aging FTP and Telnet protocols unsafe, and HP has decided to clamp down on access to networked printers through the remote-access tools. From a report on PCWorld: Some of HP's new business printers will, by default, be closed to remote access via protocols like FTP and Telnet. However, customers can activate remote printing access through those protocols if needed. "HP has started the process of closing older, less-maintained interfaces including ports, protocols and cipher suites" identified by the U.S. National Institute of Standards and Technology as less than secure, the company said in a statement. In addition, HP also announced firmware updates to existing business printers with improved password and encryption settings, so hackers can't easily break into the devices.

Bre PettisâS once said MakerBot gave you a superpower -- "You can make anything you need." But four years later, mirandakatz writes that though MakerBot promised to revolutionize society, "That never happened." At Backchannel, Andrew Zaleski has the definitive, investigative account of why the 3D printing revolution hasn't yet come to pass, culled from interviews with industry observers, current MakerBot leadership, and a dozen former MakerBot employees. As he tells it, "In the span of a few years, MakerBot had to pull off two very different coups. It had to introduce millions of people to the wonders of 3D printing, and then convince them to shell out more than $1,000 for a machine. It also had to develop the technology fast enough to keep its customers happy. Those two tasks were too much for the fledgling company."

Harvard University researchers have successfully 3D printed the first heart-on-a-chip with integrated sensors that are capable of measuring the beating of the heart. Gizmodo reports: The printed organ is made of synthetic material designed to mimic the structure and function of native tissue. It is not designed to replace failing human organs, but it can be used for scientific studies, something that is expected to rapidly increase research on new medicine. The medical breakthrough may also allow scientists to rapidly design organs-on-chips to match specific disease properties or even a patient's cells. Organs-on-chips, also known by the more technical name microphysiological systems, replicate the structure and function of living human organs. Each is made of a translucent, flexible polymer that lets scientists replicate biological environments of living organs. The chips are also clear so that the scientists can see an inner-working into how the organs work. A large part of the breakthrough was actually developing six different printable inks capable of integrating sensors within the tissue being printed. In one continuous printing process, the team 3D printed materials into a heart-on-a-chip with integrated sensors. The sensors were capable of measuring the beating of the heart. The new study has been published today in Nature Materials.

sciencehabit quotes a report from Science Magazine: If you shatter a bone in the future, a 3D printer and some special ink could be your best medicine. Researchers have created what they call "hyperelastic bone" that can be manufactured on demand and works almost as well as the real thing, at least in monkeys and rats. Though not ready to be implanted in humans, bioengineers are optimistic that the material could be a much-needed leap forward in quickly mending injuries ranging from bones wracked by cancer to broken skulls. Researchers at Northwestern University, Evanston, in Illinois are working on a hyperelastic bone, which is a type of scaffold made up of hydroxyapatite, a naturally occurring mineral that exists in our bones and teeth, and a biocompatible polymer called polycaprolactone, and a solvent. Hydroxyapatite provides strength and offers chemical cues to stem cells to create bone. The polycaprolactone polymer adds flexibility, and the solvent sticks the 3D-printed layers together as it evaporates during printing. The mixture is blended into an ink that is dispensed by the printer, layer by layer, into exact shapes matching the bone that needs to be replaced. The idea is, a patient would come in with a nasty broken bone -- say, a shattered jaw -- and instead of going through painful autograft surgeries or waiting for a custom scaffold to be manufactured, he or she could be x-rayed and a 3D-printed hyperelastic bone scaffold could be printed that same day.

Soon after the Electronic Frontier Foundation (EFF) issued a letter to HP, calling for them to apologize to customers for releasing firmware that prevents the use of non-HP ink cartridges and refilled HP cartridges, the company has responded with a temporary solution. HP "will issue an optional firmware update that will remove the dynamic security feature" for certain OfficeJet printers. Ars Technica reports: HP made its announcement in a blog post titled "Dedicated to the best printing experience." "We updated a cartridge authentication procedure in select models of HP office inkjet printers to ensure the best consumer experience and protect them from counterfeit and third-party ink cartridges that do not contain an original HP security chip and that infringe on our IP," the company said. The recent firmware update for HP OfficeJet Pro, and OfficeJet Pro X printers "included a dynamic security feature that prevented some untested third-party cartridges that use cloned security chips from working, even if they had previously functioned," HP said. For customers who don't wish to be protected from the ability to buy less expensive ink cartridges, HP said it "will issue an optional firmware update that will remove the dynamic security feature. We expect the update to be ready within two weeks and will provide details here." This customer-friendly move may just be a one-time thing. HP said it will continue to use security features that "protect our IP including authentication methods that may prevent some third-party supplies from working." Without the optional firmware update, printers will only be able to use third-party ink cartridges that have an "original HP security chip," the company said.

HP should apologize to customers and restore the ability of printers to use third-party ink cartridges, the Electronic Frontier Foundation (EFF) said in a letter to the company's CEO yesterday. From an ArsTechnica report:HP has been sabotaging OfficeJet Pro printers with firmware that prevents use of non-HP ink cartridges and even HP cartridges that have been refilled, forcing customers to buy more expensive ink directly from HP. The self-destruct mechanism informs customers that their ink cartridges are "damaged" and must be replaced. "The software update that prevented the use of third-party ink was reportedly distributed in March, but this anti-feature itself wasn't activated until September," EFF Special Advisor Cory Doctorow wrote in a letter to HP Inc. CEO Dion Weisler. "That means that HP knew, for at least six months, that some of its customers were buying your products because they believed they were compatible with any manufacturer's ink, while you had already planted a countdown timer in their property that would take this feature away. Your customers will have replaced their existing printers, or made purchasing recommendations to friends who trusted them on this basis. They are now left with a less useful printer -- and possibly a stockpile of useless third-party ink cartridges."

A federal appeals court ruled this week against Defense Distributed, the Texas organization that promotes 3D-printed guns, in a lawsuit that it brought last year against the State Department. In a 2-1 decision, the 5th Circuit Court of Appeals was not persuaded that Defense Distributed's right to free speech under the First Amendment outweighs national security concerns. From an ArsTechnica report: The majority concluded: 'Ordinarily, of course, the protection of constitutional rights would be the highest public interest at issue in a case. That is not necessarily true here, however, because the State Department has asserted a very strong public interest in national defense and national security. Indeed, the State Department's stated interest in preventing foreign nationals -- including all manner of enemies of this country -- from obtaining technical data on how to produce weapons and weapon parts is not merely tangentially related to national defense and national security; it lies squarely within that interest.'

An anonymous reader quotes some harsh allegations from Myce.com: Thousands of HP printers around the world started to show error messages on the same day, the 13th of September... HP printers with non-HP cartridges started to show the error message, "One or more cartridges appear to be damaged. Remove them and replace them with new cartridges"... When [Dutch online retailer 123ink] emailed their customers asking them if they wanted to check if their printer also had issues, they received replies from more than 1,000 customers confirming the issue...

Consumers who complained to HP were told the error was caused by using non-HP cartridges. A day later HP withdrew that statement and explained the issues were a side effect of a firmware update, [but] printers without any internet access started to reject non-HP cartridges. Therefore it's very unlikely that a firmware update caused the issues and the only other logical explanation is that HP programmed a date in its firmware on which non-HP cartridges would no longer be accepted.
"Printer worked fine for nine months," complains one of many angry users on HP's web site. "Then on 9/13 HP uploaded without my permission a firmware update that caused a message 'damaged cartridge' for all my cartridges and then it refused to print."

HP has agreed to a deal with Samsung to acquire their printer business for $1.05 billion, a deal that will be the largest print acquisition in HP's history. USA Today reports: "The acquisition of Samsung's printer business allows us to deliver print innovation and create entirely new business opportunities with far better efficiency, security, and economics for customers," said HP president and CEO Dion Weisler in a statement. The Samsung deal would give HP access to 6,500 printing patents as well as 1,300 researchers and engineers "with advanced expertise in laser printer technology." While this deal is being negotiated, Samsung's mobile phone business has been navigating a recall of its Galaxy Note 7 smartphones over issues with batteries catching fire and exploding. One of the most recent accidents reported involved a six-year-old boy in New York, who was using the device when it "suddenly burst into flames."

An anonymous reader quotes a report from FedScoop: Smartphones equipped with special programming can become a sophisticated spy sensor capable of stealing designs from a 3D printer -- just by measuring the noise and electromagnetic radiation the printer emits. Researchers from the University of Buffalo recently discovered how a smartphone on a bench about 8 inches away from a 3D printer could allow someone to reconstruct a simple object being printed with 94 percent accuracy. Complex objects can be copied with 90 percent accuracy. The attack basically reverse-engineers the printing blueprint by reconstructing the movement of the nozzle from the electromagnetic and acoustic energy it generates while working. Most information came from electromagnetic waves, which accounted for about 80 percent of the useful data. The remaining 20 percent came from acoustic waves. Wenyao Xu, assistant professor in the University of Buffalo's Department of Computer Science and Engineering, is the lead author of the study, "My Smartphone Knows What You Print: Exploring Smartphone-Based Side-Channel Attacks Against 3D Printers," which will be presented at the Association for Computing Machinery's 23rd annual Conference on Computer and Communications Security next month in Austria.

An anonymous reader quotes a report from Reuters: Hewlett Packard Enterprise Co will spin off and merge its non-core software assets with Britain's Micro Focus International Plc in a deal worth $8.8 billion, the companies said on Wednesday. The move is part of HPE Chief Executive Meg Whitman's plans to shift HPE's strategy to a few key areas such as networking, storage and technology services since the company separated last year from computer and printer maker HP Inc. The deal with Micro Focus, a multinational software company based in Newbury, United Kingdom, was announced along with HPE's latest quarterly earnings. In the third quarter, HPE reported net revenue of $12.2 billion, down 6 percent from $13.1 billion a year earlier. In the deal, HPE is sending one of the British firms it acquired back to where it started. HPE acquired part of its software portfolio through the $10.3 billion purchase of Britain's Autonomy Corp Plc in 2011. HP's $11 billion purchase of Autonomy was supposed to form the central part of the U.S. group's move into software. Other HPE assets that will be merged include software for application delivery management, big data, enterprise security, information management and governance and IT Operations management businesses.
