Bambu's X1C and P1P 3D printers started printing unattended, overnight, and without any additional user input, according to user reports from r/BambuLab and X. The Verge reports: Some woke up to failed prints. Some found a second copy of a previous print. And at least a few found their Bambu X1C or P1P had started smacking itself apart -- damaging components -- while trying to print a second copy atop the object they'd actually asked for. What happened? In an official blog post, Bambu says it's still investigating but suspects that a cloud outage is to blame. The company says its servers had two brief outages on Tuesday morning where the servers couldn't confirm that the printers had actually printed -- but instead of failing gracefully, they wound up sending the same print job again and again until it went through, Bambu's staff believes. "Simply explained, the print job sent to the printer before was trapped on the cloud and had a delayed start," writes Bambu.

When contacted by The Verge, Bambu would not go quite so far as to promise free repairs and replacements for all affected customers but says anyone who's suffered any damage should reach out to Bambu support ASAP. "For damage caused by this incident, we will offer the necessary solutions to our customers impacted by the Cloud Outage, in the form of part replacements or a printer replacement if the situation demands it," spokesperson Taylor Liu tells me.

HP all-in-one printer owners, upset that their devices wouldn't scan or fax when low on ink, were handed a partial win in a northern California court late last week after a judge denied HP's motion to dismiss their suit. From a report: The plaintiffs argued in their amended class action complaint that HP withheld vital information by including software in its all-in-one printer/scanner/fax machines that disabled non-printing functions when out of ink and not telling buyers that was the case. "It is well-documented that ink is not required in order to scan or to fax a document, and it is certainly possible to manufacture an All-in-One printer that scans or faxes when the device is out of ink," the plaintiffs argued in their complaint.

The amended complaint was filed in February this year after US federal Judge Beth Labson Freeman dismissed the suit on the grounds that it hadn't properly stated a claim. Armed with their amended complaint, lawyers for San Franciscan Gary Freund and Minneapolis resident Wayne McMath have succeeded at not only making relevant claims, but also surviving an attempt by HP to have the entire case dismissed for a second time. In the amended complaint, Freund and McMath's lawyers argue that HP's move to disable devices that were low on ink was intentional, citing HP's own comments from a support forum post in which an HP support agent told a user complaining of similar issues that their "HP printer is designed in such a way that with the empty cartridge or without the cartridge [the] printer will not function."

Last year, Queens resident David Leacraft filed a lawsuit against Canon claiming that his Canon Pixma All-in-One printer won't scan documents unless it has ink. According to The Verge's Sean Hollister, it has quietly ended in a private settlement rather than becoming a big class-action. From the report: I just checked, and a judge already dismissed David Leacraft's lawsuit in November, without (PDF) Canon ever being forced to show what happens when you try to scan without a full ink cartridge. (Numerous Canon customer support reps wrote that it simply doesn't work.) Here's the good news: HP, an even larger and more shameless manufacturer of printers, is still possibly facing down a class-action suit for the same practice.

As Reuters reports, a judge has refused to dismiss a lawsuit by Gary Freund and Wayne McMath that alleges many HP printers won't scan or fax documents when their ink cartridges report that they've run low. Among other things, HP tried to suggest that Freund couldn't rely on the word of one of HP's own customer support reps as evidence that HP knew about the limitation. But a judge decided it was at least enough to be worth exploring in court. "Plaintiffs have plausibly alleged that HP had a duty to disclose and had knowledge of the alleged defect," wrote Judge Beth Labson Freeman, in the order denying almost all of HP's current attempts to dismiss the suit.

Interestingly, neither Canon nor HP spent any time trying to argue their printers do scan when they're low on ink in the lawsuit responses I've read. Perhaps they can't deny it? Epson, meanwhile, has an entire FAQ dedicated to reassuring customers that it hasn't pulled that trick since 2008. (Don't worry, Epson has other forms of printer enshittification.) HP does seem to be covering its rear in one way. The company's original description on Amazon for the Envy 6455e claimed that you could scan things "whenever". But when I went back now to check the same product page, it now reads differently: HP no longer claims this printer can scan "whenever" you want it to. Now, we wait to see whether the case can clear the bars needed to potentially become a big class-action trial, or whether it similarly settles like Canon, or any number of other outcomes.

Long-time Slashdot reader SonicSpike shares a report from NBC News: A divided Supreme Court on Tuesday allowed the Biden administration to enforce regulations aimed at clamping down on so-called ghost guns -- firearm-making kits available online that people can assemble at home. The court, which has a 6-3 conservative majority, in a brief order (PDF) put on hold a July 5 ruling by a federal judge in Texas that blocked the regulations nationwide. The vote was 5-4, with conservatives Chief Justice John Roberts and Justice Amy Coney Barrett joining the three liberal justices in the majority.

The federal Bureau of Alcohol, Tobacco, Firearms and Explosives, commonly known as ATF, issued the regulations last year to tackle what it claims has been an abrupt increase in the availability of ghost guns. The guns are difficult for law enforcement to trace, with the administration calling them a major threat to public safety. The rule clarified that ghost guns fit within the definition of 'firearm' under federal law, meaning that the government has the power to regulate them in the same way it regulates firearms manufactured and sold through the traditional process. The regulations require manufacturers and sellers of the kits to obtain licenses, mark the products with serial numbers, conduct background checks and maintain records.

Printer manufacturer Canon is warning that sensitive Wi-Fi settings don't automatically get wiped during resets, so customers should manually delete them before selling, discarding, or getting them repaired to prevent the settings from falling into the wrong hands. From a report: "Sensitive information on the Wi-Fi connection settings stored in the memories of inkjet printers (home and office/large format) may not be deleted by the usual initialization process," company officials wrote in an advisory on Monday. They went on to say that manual wiping should occur "when your printer may be in the hand of any third party, such as when repairing, lending or disposing the printer."

Like many printers these days, those from Canon connect to networks over Wi-Fi. To do this, users must provide the SSID name, the password preventing unauthorized access to the network, and in some cases, additional information such as Wi-Fi network type, the local network IP address, the MAC address, and network profile. It would be reasonable to assume that performing a simple factory reset that returns all settings to their defaults would be enough to remove these settings, but Monday's advisory indicated that isn't necessarily the case. In the event this information is exposed, malicious actors could use them to gain unauthorized access to a network hosting a Canon printer.

The world's largest community of 3D-printed homes, located in Texas, has unveiled its first completed house. CNN reports: With walls "printed" using a concrete-based material, the single-story structure is the first of 100 such homes set to welcome residents starting September. The community is part of a wider development in Georgetown, Texas called Wolf Ranch. It's located about 30 miles north of Austin, the state capital, and is a collaboration between Texas construction firm ICON, homebuilding company Lennar and Danish architecture practice Bjarke Ingels Group (BIG). On Saturday prospective buyers toured around the finished model home at the project's grand opening, and some of the units have already sold, ICON spokesperson Cara Caulkins told CNN via email.

Images of the newly completed building shared by the company show brightly lit interiors and curved gray walls. The walls are made from a concrete mix called Lavacrete, which is piped into place using 46-foot-wide robotic printers. After the walls are printed, the doors, windows and roofs -- all of which are equipped with solar panels -- are installed. ICON says more than a third of the homes' walls have now been printed, and the properties currently on offer are being sold at $475,000 to $599,000. The 3D-printed homes range in size from 1,500 to 2,100 square feet and have three to four bedrooms.

An anonymous reader quotes a report from the Washington Post: If you're printing something on actual paper, there's a good chance it's important, like a tax form or a job contract. But popular printing products and services won't promise not to read it. In fact, they won't even promise not to share it with outside marketing firms. The spread of digital file-sharing -- along with obnoxious business practices by printing manufacturers -- has pushed many U.S. households to give up at-home printers and rely on nearby printing services instead. At the same time, major printer manufacturers have adopted mobile apps and cloud-based storage, creating new opportunities to collect personal data from customers. Whether you're walking to the corner store or sending your files to the cloud, it's tough to figure out whether you're printing in private.

Ideally, printing services should avoid storing the content of your files, or at least delete daily. Print services should also communicate clearly upfront what information they're collecting and why. Some services, like the New York Public Library and PrintWithMe, do both. Others dodged our questions about what data they collect, how long they store it and whom they share it with. Some -- including Canon, FedEx and Staples -- declined to answer basic questions about their privacy practices. Wondering whether your printer app or printing service stores the content of your documents? Here's The Washington Post Help Desk's at-a-glance guide to printer privacy. Here's a summary of each company's privacy policy as it pertains to storing the content of your files:

HP: HP's privacy policy states that it does not store the content of files when using their printers or HP Smart app, providing reassurance that they do not invade privacy by snooping into print jobs.
Canon: Canon's privacy policy indicates that it can collect personal data, including files and content, which may be used for marketing purposes. However, Canon did not disclose whether they store, use, or share the content of printed documents.
FedEx: FedEx's privacy policy states that it collects user-uploaded information, including the contents of documents uploaded for printing services, leaving room for potential advertising or sharing with third parties. Although FedEx prioritizes customer privacy, it did not specify the extent of encryption or whether document content is included.
UPS: While the UPS Store, a subsidiary of UPS, can store the contents of printed documents, it does not use this information for marketing or advertising without user consent. The storage duration is undisclosed, but UPS honors customer requests for data deletion.
Staples: According to Staples' privacy policy, the company can store personal data such as copy/print materials, driver's license numbers, passport numbers, and mail contents. They may also use copy/print materials for advertising. The duration of data storage is not disclosed.
PrintWithMe: PrintWithMe, a company placing printers in shared spaces, temporarily stores printed documents with a third-party cloud provider for 24 hours. CEO Jonathan Treble assures that the data is never used for advertising.
Your local library: The New York Public Library, one of the largest library systems, does not store the contents of printed documents. Their computers only retain file names and delete them at the end of the day. However, privacy policies may vary among different libraries, so it is advisable to inquire beforehand.

An anonymous reader quotes a report from Ars Technica: HP printers have received a lot of flak historically and recently for invasive firmware updates that end up preventing customers from using ink with their printers. HP also encourages printer customers to sign up for HP+, a program that includes a free ink-subscription trial and irremovable firmware that allows HP to brick the ink when it sees fit. Despite this, HP markets dozens of its printers with Dynamic Security and the optional HP+ feature as being in the Electronic Product Environmental Assessment Tool (EPEAT) registry, suggesting that these printers are built with the environment in mind and, more specifically, do not block third-party ink cartridges. Considering Dynamic Security and HP+ printers do exactly that, the International Imaging Technology Council (IITC) wants the General Electronics Council (GEC), which is in charge of the EPEAT registry, to revoke at least 101 HP printer models from the EPEAT registry, which HP has "made a mockery of."

For a printer to make the EPEAT registry, it's supposed to comply with the EPEAT Imaging Equipment Category Criteria, which is based on the 1680.2-2012 IEEE Standard for Environmental Assessment of Imaging Equipment (PDF). The IITC is hung up on section 4.9.2.1, which requires that registered products do not "prevent the use of nonmanufacturer cartridges and non-manufacturer containers" and that vendors provide documentation showing that the device isn't "designed to prevent the use of a non-manufacturer cartridge or non-manufacturer container." Well, as the IITC and consumers who found their inked bricked mid-print will tell you, that sounds an awful lot like what HP does with its Dynamic Security printers.

Diving deeper, the IITC's complaint claims that "in the last 8 weeks alone, HP has released 4 killer firmware updates targeting dozens of EPEAT-registered inkjet printers." "At least one of these recent updates specifically targeted a single producer of remanufactured cartridges while not having any impact on non-remanufactured third-party cartridges using functionally identical non-HP chips," the complaint reads. The trade group also claimed at least 26 "killer firmware updates" occurred on EPEAT-registered HP laser printers since October 2020. The complaint argues that the error message that users see -- "The indicated cartridges have been blocked by the printer firmware because they contain non-HP chips. This printer is intended to work only with new or reused cartridges that have a new or reused HP chip. Replace the indicated cartridges to continue printing" -- go against EPEAT requirements, yet HP markets dozens of Dynamic Security printers with EPEAT ecolabels. "The nonprofit trade association was founded in 2000 and says it represents 'toner and inkjet cartridge remanufacturers, component suppliers, and cartridge collectors in North America,'" notes Ars. "So its members stand to lose a lot of money from tactics like Dynamic Security. The IITC already filed a complaint to the GEC about HP in 2019 for firmware blocking non-HP ink, but there didn't seem to be any noticeable results."

"The group is biased regarding this topic, but its complaint still mirrors many problems and concerns that consumers and class-action lawsuits have detailed regarding HP printers' exclusive stance on ink. You can find the full complaint here."

An anonymous reader shares a report: Amazon's No. 1 bestselling printer is the HP Deskjet 2755e. It's not hard to see why. For just $85, you get a wireless color printer, scanner, and six months of free ink. It also comes with HP Plus, one of the most dastardly schemes Big Inkjet has ever unleashed. I'm not talking about how printers quietly waste their own ink, or pretend cartridges are empty when they're not, or lock out official cartridges from other regions. Heck, I'm not even talking about "Dynamic Security," the delightful feature where new HP firmware updates secretly contain malware that blocks batches of third-party cartridges while pretending to harden your printhead against hacks. No, the genius of HP's latest scheme is that it's hiding in plain sight, daring you to unwittingly sign away your rights. Take the free ink, and HP controls your printer for life.

First introduced in 2020 at the height of the pandemic, HP Plus was built around FOMO right from the start. You get just seven days to claim your free ink, starting the moment you plug a new printer into the wall. Act now, and it'll also extend your warranty a full year, give you an "Advanced HP Smart app," and plant trees on your behalf. Because why wouldn't you want to save the forest? Here's one reason, as detailed in a new complaint by the International Imaging Technology Council (IITC) that might turn into a false advertising fight: HP Plus comes with a firmware update that utterly removes your printer's ability to accept third-party ink. You have to buy "genuine" HP ink as long as you use the printer.

Last week the Telegraph reported that a recent firmware update to HP printers "prevents customers from using any cartridges other than those fitted with an HP chip, which are often more expensive. If the customer tries to use a non-HP ink cartridge, the printer will refuse to print."

Some HP "Officejet" printers can disable this "dynamic security" through a firmware update, PC World reported earlier this week. But HP still defends the feature, arguing it's "to protect HP's innovations and intellectual property, maintain the integrity of our printing systems, ensure the best customer printing experience, and protect customers from counterfeit and third-party ink cartridges that do not contain an original HP security chip and infringe HP's intellectual property."

Meanwhile, Engadget now reports that "a software update Hewlett-Packard released earlier this month for its OfficeJet printers is causing some of those devices to become unusable." After downloading the faulty software, the built-in touchscreen on an affected printer will display a blue screen with the error code 83C0000B. Unfortunately, there appears to be no way for someone to fix a printer broken in this way on their own, partly because factory resetting an HP OfficeJet requires interacting with the printer's touchscreen display. For the moment, HP customers report the only solution to the problem is to send a broken printer back to the company for service.
BleepingComputer says the firmware update "has been bricking HP Office Jet printers worldwide since it was released earlier this month..." "Our teams are working diligently to address the blue screen error affecting a limited number of HP OfficeJet Pro 9020e printers," HP told BleepingComputer... Since the issues surfaced, multiple threads have been started by people from the U.S., the U.K., Germany, the Netherlands, Australia, Poland, New Zealand, and France who had their printers bricked, some with more than a dozen pages of reports.

"HP has no solution at this time. Hidden service menu is not showing, and the printer is not booting anymore. Only a blue screen," one customer said.

"I talked to HP Customer Service and they told me they don't have a solution to fix this firmware issue, at the moment," another added.

Hewlett-Packward printers recently got a firmware update that "blocks customers from using cheaper, non-HP ink cartridges," reports the Telegraph: Customers' devices were remotely updated in line with new terms which mean their printers will not work unless they are fitted with approved ink cartridges. It prevents customers from using any cartridges other than those fitted with an HP chip, which are often more expensive. If the customer tries to use a non-HP ink cartridge, the printer will refuse to print.

HP printers used to display a warning when a "third-party" ink cartridge was inserted, but now printers will simply refuse to print altogether.

The printer company said it issued the update to reduce the risk of malware attacks, saying "third-party cartridges that use non-HP chips or circuitry can pose risks to the hardware performance, print quality, and security." It also said it used regular updates to improve its services, such as introducing alerts for some customers telling them when their ink is running low. However, according to HP's website, the company also blocks the use of rival cartridges in order to "maintain the integrity of our printing systems, and protect our intellectual property".

Outraged customers have flooded social media with complaints, saying they felt "cheated" by the update. HP ink cartridges can cost more than double the price of third-party offerings... Some customers can choose to disable HP's cartridge-blocking feature in the printer's settings, HP said, but it depends on the printer model. Others will be stuck with a printer that only works if they commit to spending more on ink cartridges approved by HP.

NASA has developed a new superalloy called GRX-810 that could lead to stronger, more durable parts for airplanes and spacecraft. SciTechDaily reports: GRX-810 is an oxide dispersion strengthened alloy. In other words, tiny particles containing oxygen atoms spread throughout the alloy enhance its strength. Such alloys are excellent candidates to build aerospace parts for high-temperature applications, like those inside aircraft and rocket engines, because they can withstand harsher conditions before reaching their breaking points. Current state-of-the-art 3D printed superalloys can withstand temperatures up to 2,000 degrees Fahrenheit. Compared to those, GRX-810 is twice as strong, over 1,000 times more durable, and twice as resistant to oxidation.

"This new alloy is a major achievement," said Dale Hopkins, deputy project manager of NASA's Transformational Tools and Technologies project. "In the very near future, it may well be one of the most successful technology patents NASA Glenn has ever produced." GRX-810 was developed under NASA's Transformational Tools and Technologies project, with support from the agency's Game Changing Development Program. The peer-reviewed paper has been published in the journal Nature.

An anonymous reader quotes a report from The Guardian: Red sand shifts under the boots of the crew members. In the distance, it appears that a rocky mountain range is rising out of the Martian horizon. A thin layer of red dust coats the solar panels and equipment necessary for the year-long mission. This landscape isn't actually 145m miles away. We are in a corner of the Nasa Johnson Space Center in Houston, in a large white warehouse right next to the disc golf course and on the tram route for tourists and school groups. But starting this June, four volunteer test subjects will spend a year locked inside, pretending to live on Mars. Nasa researchers say they're doing everything they can to make it as realistic as possible so they can learn the impact that a year in isolation with limited resources has on human health. "As we move from low Earth orbit, from moon to Mars, we're going to have a lot more resource restrictions than we have on the International Space Station and we're going to be a lot further from Earth or any help from Earth," said Dr Grace Douglas, the principal investigator for the Crew Health Performance Exploration Analog, or Chapea for short.

The four crew members will live in a small housing unit that was constructed using a huge 3D printer to simulate how Nasa may create structures on the Martian surface with Martian soil. They'll conduct experiments, grow food and exercise -- and be tested regularly so scientists can learn what a year on Mars could do to the body and mind. "This is really an extreme circumstance," said Dr Suzanne Bell, who leads the Behavioral Health and Performance Laboratory at the Nasa Johnson Space Center. "You're asking for individuals to live and work together for over a one-year period. Not only will they have to get along well, but they'll also have to perform well together."

Watching four people spend a year in a 3D-printed box is Nasa's next small step toward landing humans on the surface of Mars. Nasa says it hopes to send humans to the red planet as early as the 2030s. The first mission could be a nine-month trip one-way, and could leave the astronauts on the surface for two and a half years before starting the long trip back home. Preparations for that trek are already well under way with the agency's Artemis program. Artemis is sending astronauts back to the Moon for the first time since 1972, including the first person of color and woman to walk on another celestial body. As part of the Artemis missions, Nasa is also launching Gateway, a space station that will orbit the Moon and serve as a pit stop for Mars-bound missions. Getting to the Moon means getting to Mars, and getting to Mars means testing the physical and behavioral health of a crew in isolation. That's where Chapea comes in.

In every copy of macOS that has shipped since 2018, Apple has included the original Bitcoin whitepaper by Satoshi Nakamoto, and no-one seems to know why. From a report: The baffling discovery (or rediscovery - see below) was recently made by developer and waxy.org writer Andy Baio, who stumbled upon the PDF document while trying to fix a problem with his printer. Anyone with a Mac running macOS Mojave or later can see the PDF for themselves by typing the following command into Terminal:

open /System/Library/Image\ Capture/Devices/VirtualScanner.app/Contents/Resources/simpledoc.pdf

If you're running macOS 10.14 or later, the 184 KB Bitcoin PDF should immediately open in Preview. The document can also be located via Finder: Navigate to Macintosh HD -> System -> Library -> Image Capture -> Devices, then open the Contents -> Resources folder. The whitepaper titled "simpledoc.pdf" should be in there.

Longtime Slashdot reader destinyland shares a report from Space.com: The Relativity Space rocket, called Terran 1, lifted off from Launch Complex 16 at Florida's Cape Canaveral Space Force Station at 8:25 p.m. EST (0025 GMT on March 23), kicking off a test flight called "Good Luck, Have Fun" (GLHF). Terran 1 performed well initially. For example, it survived Max-Q -- the part of flight during which the structural loads are highest on a rocket -- and its first and second stages separated successfully. But something went wrong shortly thereafter, at around three minutes into the flight, when the rocket failed to reach orbit.

"No one's ever attempted to launch a 3D-printed rocket into orbit, and, while we didn't make it all the way today, we gathered enough data to show that flying 3D-printed rockets is viable," Relativity Space's Arwa Tizani Kelly said during the company's launch webcast on Wednesday night. "We just completed a major step in proving to the world that 3D-printed rockets are structurally viable," she added.

In the 1970s, Bob Metcalfe helped develop the primary technology that lets you send email or connect with a printer over an office network. From a report: In June 1972, Bob Metcalfe, a 26-year-old engineer fresh out of graduate school, joined a new research lab in Palo Alto, Calif., as it set out to build something that few people could even imagine: a personal computer. After another engineer gave up the job, Dr. Metcalfe was asked to build a technology that could connect the desktop machines across an office and send information between them. The result was Ethernet, a computer networking technology that would one day become an industry standard. For decades, it has connected PCs to servers, printers and the internet in corporate offices and homes across the globe.

For his work on Ethernet, the Association for Computing Machinery, the world's largest society of computing professionals, announced on Wednesday that Dr. Metcalfe, 76, would receive this year's Turing Award. Given since 1966 and often called the Nobel Prize of computing, the Turing Award comes with a $1 million prize. When Dr. Metcalfe arrived at the Palo Alto Research Center -- a division of Xerox nicknamed PARC -- the first thing he did was connect the lab to the Arpanet, the wide-area network that later morphed into the modern internet. The Arpanet transmitted information among about 20 academic and corporate labs across the country. But as PARC researchers designed their personal computer, called the Alto, they realized they needed a network technology that could connect personal computers and other devices within an office, not over long distances.

sciencehabit shares a report from Science Magazine: Researchers have designed a robot that can create and cook a cake with up to seven ingredients, more than any other printed food to date. The scientists built their programmable patisserie by retrofitting a 3D printer with nozzles designed to squeeze out selected ingredients. They then programmed it to dispense those into layered cakes. Initial trials resulted in triangular gobs of sweet goo, so the researchers came up with a winning recipe that could hold its own. They nested softer ingredients, such as jelly and banana puree, inside of stiffer ingredients, such as peanut butter and Nutella, then reinforced those with hefty doses of graham cracker crust. Then, they broiled the crust with a laser and topped the cake with frosting and cherry glaze. The result? A cheesecake, of sorts.

Despite its novelty, the computer-guided cook may not be able to battle it out under the stern eye of a guest judge any time soon -- each slice took about 30 minutes to print. Further in the future, however, better printers could make some cooking automatic, freeing people from kitchen tasks they may find tiring or repetitive -- assuming you don't enjoy those things. A food printer could also be programmed to dispense meals with precision-controlled nutrient and calorie content, helping prepare food for those on strict diets. The study has been published in the journal npj Science of Food.

"Based on initial data review, vehicle is healthy," Relativity Space tweeted today. "More info to follow on cause of aborts today. Thanks for playing."

Remaining back on the launchpad is the largest 3D printed object ever to exist. And they're still hoping to launch it into space.

They'd planned a launch this morning from Cape Canaveral, Florida of a 110-foot rocket (33.5 meters) on a mission they're calling GLHF — "Good Luck, Have Fun".

The rocket's makers — California-based Relativity Space — call it "the world's first 3D printed rocket." A full 85% of the rocket's weight comes from 3D printed parts, explains Wired, and "only the computing system, electronics, and readily available parts like fasteners were not." Named Terran 1, the 7.5-foot-wide rocket (2.2 meters) inaugurates the company's ambitious plans for 3D printing in space: Relativity Space wants to use Terran 1 to (comparatively) cheaply lift satellites for other companies and NASA into Earth orbit. It also plans to construct Terran R, a larger, more powerful, fully reusable rocket that the company hopes will compete with SpaceX's Falcon 9, which has a smaller payload capacity and only reuses the rocket's first stage. In late 2024, Relativity plans to test using Terran R to launch payloads to Mars; another startup, Impulse Space, will provide the lander.
From the company's web site: Like its structure, all Relativity engines are 3D printed and use liquid oxygen and liquid natural gas, which are not only the best for rocket propulsion, but also for reusability, and the easiest to eventually transition to methane on Mars.
The tagline for the company's Twitter feed says they're "Building humanity's multiplanetary future." And excitement is running high, reports Spaceflight Now" "There are a number of firsts here potentially on this rocket," said Josh Brost, vice president of revenue operations at Relativity Space....

"Hard to believe the day is nearly here to launch Terran 1, our first rocket!" Tim Ellis, co-founder and CEO of Relativity Space tweeted Tuesday....

The company now boasts some 1,000 employees, a million-square-foot headquarters and factory in Long Beach, California, and $1.3 billion in venture capital and equity fundraising, including an early $500,000 investment from billionaire Mark Cuban. In 2021, the company reached a valuation of $4.2 billion before launching any rockets....

"No new company has ever had their liquid rocket make it to space on their first attempt," Brost, also a former engineer and manager at SpaceX, told Spaceflight Now in a pre-launch interview. "So if everything goes incredibly well, and we achieve orbit on our first launch ... that would be a remarkable milestone for us, which we would be, of course, over the moon excited about. But that doesn't define success for us."
Wired adds that they're not the only company working on space-related 3D printing: Australia's Fleet Space has already been producing lightweight, 3D-printed radio frequency antennas for satellites. Next year, using printers half the size of a bus, they plan to create a satellite constellation called Alpha that will be entirely 3D-printed.... Flavia Tata Nardini, the company's CEO, believes space-based 3D printing is coming next. "In my ideal future, in 10 to 15 years, I won't have to launch satellites from here; I can build them up there."

An anonymous reader quotes a report from Ars Technica: HP customers are showing frustration online as the vendor continues to use firmware updates to discourage or, as users report, outright block the use of non-HP-brand ink cartridges in HP printers. HP has already faced class-action lawsuits and bad publicity from "dynamic security," but that hasn't stopped the company from expanding the practice. Dynamic security is a feature used by HP printers to authenticate ink cartridges and prevent use of cartridges that aren't HP-approved. As the company explains: "Dynamic security relies on the printer's ability to communicate with the security chips or electronic circuitry on the cartridges. HP uses dynamic security measures to protect the quality of our customer experience, maintain the integrity of our printing systems, and protect our intellectual property. Dynamic security equipped printers are intended to work only with cartridges that have new or reused HP chips or electronic circuitry. The printers use the dynamic security measures to block cartridges using non-HP chips or modified or non-HP electronic circuitry. Reused, remanufactured, and refilled cartridges that reuse the HP chip or electronic circuitry are unaffected by dynamic security."

HP is set on continuing to use DRM to discourage its printer customers from spending ink and toner money outside of the HP family. "HP have updated their printers to outright ban 'non-HP' ink! They no longer shows the 'can't guarantee quality' message, but instead cancels your print completely until you inset a HP ink cartridge," Reddit user grhhull posted Tuesday. "After contacting HP, they advised 'this is due to the recent 'update' of all printers.'" It's unclear when HP issued updates for which model printers, but there are alleged customer complaints online stemming from late last year, showing plenty of customers surprised their printer no longer worked with non-HP ink cartridges after an update. Some pointed to third-party brands they had relied on for years.

HP community support threads include complaints about the OfficeJet 7740 and OfficeJet Pro 6970. HP lists both printers, as well as others, as able to circumnavigate dynamic security under specific conditions. However, HP's support page states this only applies to models manufactured before December 1, 2016. For more examples, there are comments on HP's support community suggesting that HP's OfficeJet 6978 and 6968 were recently affected. Both printers are discontinued, but HP's product pages make it clear that the fickle nature of dynamic security means that third-party ink could stop working at any time. And HP's dynamic security page also leaves the door open for the sudden bricking of functioning ink: "Firmware updates delivered periodically over the internet will maintain the effectiveness of the dynamic security measures," the page reads. "Updates can improve, enhance, or extend the printer's functionality and features, protect against security threats, and serve other purposes, but these updates can also block cartridges using a non-HP chip or modified or non-HP circuitry from working in the printer, including cartridges that work today."

An anonymous reader quotes a report from Ars Technica: Cheap, light, flexible, yet robust circuit boards are critical for wearable electronics, among other applications. In the future, those electronics might be printed on flexible circuits made out of bacterial cultures used to make the popular fermented black tea drink called kombucha, according to a recent paper posted to the arXiv preprint server. "Nowadays kombucha is emerging as a promising candidate to produce sustainable textiles to be used as eco-friendly bio wearables," co-author Andrew Adamatzky, of the University of the West of England in Bristol, old New Scientist. "We will see that dried -- and hopefully living -- kombucha mats will be incorporated in smart wearables that extend the functionality of clothes and gadgets. We propose to develop smart eco-wearables which are a convergence of dead and alive biological matter."

Adamatzky previously co-authored a 2021 paper demonstrating that living kombucha mats showed dynamic electrical activity and stimulating responses, as well as a paper last year describing the development of a bacterial reactive glove to serve as a living electronic sensing device. Inspired by the potential of kombucha mats for wearable electronics, he and his latest co-authors have now demonstrated that it's possible to print electronic circuits onto dried SCOBY mats. The team used commercially sourced kombucha bacteria to grow their mats, then air-dried the cultures on plastic or paper at room temperature. The mats don't tear easily and are not easily destroyed, even when immersed in water for several days. One of the test mats even survived oven temperatures up to 200 C (392 F), although the mats will burn when exposed to an open flame. Adamatzky et al. were able to print conductive polymer circuits onto the dried kombucha mats with an aerosol jet printer and also successfully tested an alternative method of 3D printing a circuit out of a conductive polyester/copper mix. They could even attach small LEDs to the circuits with an epoxy adhesive spiked with silver, which were still functioning after repeatedly being bent and stretched.

According to Adamatzky et al., unlike the living kombucha mats he worked with previously, the dried SCOBY mats are non-conductive, confining the electrical current to the printed circuit. The mats are also lighter, cheaper, and more flexible than the ceramic or plastic alternatives. Potential applications include wearable heart rate monitors, for instance, and other kombucha-based devices. "Future research will be concerned with printing advanced functional circuits, capable for detecting -- and maybe recognizing -- mechanical, optical, and chemical stimuli," the authors concluded.
