The topic of open source has been a touchy one for MakerBot over the past decade.The one-time 3D-printing darling was the subject of some serious smack talk among the maker community when it stopped disclosing machine design in 2012 — a departure from the company’s roots as in the open-source Rep-Rap community.Announced this week, MakerBot Labs doesn’t mark a full return to those roots, but it does find the company carving out a niche for the DIY community that was once a driving force in its rapid growth.“I understand the history,” CEO Nadav Goshen told TechCrunch during a phone call this week, “This is one step in the direction.Openness for us doesn’t mean we have to compromise on quality or ease of use.We’re trying to take responsibility for both.”
The growth in 3-D printing is allowing manufacturers to reduce production time and save money.But the predicted mass production of 3-D printed products for consumers has not yet come to pass.An article in Chemical & Engineering News (C), the weekly newsmagazine of the American Chemical Society, explains how industry is using the technology.Over the past decade, 3-D printing has been portrayed as the next big manufacturing trend, and companies are now starting to take advantage of the technology.For example, as C Senior Correspondent Alexander Tullo reports, Volkswagen has started using 3-D printers for tools and parts, which has saved the company time and hundreds of thousands of dollars.Others are also getting on board, spurring global sales of 3-D printing equipment and related materials to grow to $2.7 billion last year.
Microsoft, of all people, has offered a recipe for cooling the Raspberry Pi 3.Redmond's put the Pi to work on some AI-related chores and found the poor wee things run rather hot when working near their peak capacity.As the infrared shots below show, the Pi runs quite cool at first (left) but after a few minutes of exertion the Broadcom BCM2837 get unpleasantly hot.So hot, in fact, that the quad-core CPU quickly hits about 85 C, well beyond egg-frying territory and also the mark at which the Pi either throttles back its CPU or shuts down to save itself.Slower CPUs are an obvious hindrance to SkyNet's plans to hunt down and kill humanity using the AIs we created ourselves.Hence Microsoft's 3D printing plan for a fan mount that positions a small blower just above the rPI's CPU.

Researchers are proposing a floating antenna design to help alleviate overcrowding in the electromagnetic frequency spectrum and boost wireless signals.The researchers, from the ElectroScience Laboratory (ESL) at Ohio State University, are designing suspended high-gain millimeter-wave antenna arrays constructed through a combination of 3D printing and MEMS (Micro-Electro-Mechanical Systems).Overcrowding will become more of an issue when 5G arrives.Already packed lower frequencies will come under increased pressure as interconnected devices proliferate and require higher bandwidth.Higher frequencies, meanwhile, are more prone to interference.The silicon substrates which antennas today are often mounted on can weaken the wireless signals and cause losses.

It’s been a fascinating couple of years for high tech sneaker heads, between self-lacing Nikes and Adidas’ experiments with 3D printed midsoles and biodegradable yarn.Asics isn’t generally uttered in the same breath as those sorts of bleeding edge offerings, but the running shoe company has just debuted a pretty compelling new take on the manufacturing process.The new technique, developed alongside Taiwan’s Tayin Research & Development Co., Ltd., promises customization, while offering up a relatively sustainable solution to shoemaking — two concepts that tend not to go hand-in-hand in the garment industry.According to Asics, the process utilizes heat generated by microwaves to fuse different materials together, in order to create the shoe’s midsole.Asics is just offering a sneak preview of the technology at the moment, as it’s still in the testing phase — but if all goes according to plan, it could be rolled out to the point of sale.Somewhere down the road, the company plans to bring actual production microwaves to shops, so customers can select their custom shoe design in person.
The 3D printers of 2017 aren’t just bringing your ideas to life in multiple dimensions — they’re engraving and carving those dimensions as well.Meet the Mooz, a 3D printer that is not only fully modular, but can also operate as a CNC carver and laser engraver.Because everyone is expected to be a jack of all trades these days — even our machines.Thanks to the easily constructible design of the Mooz, you can quickly vary the shape of the modular device, allowing you to adjust the speed and resolution capabilities of the printer.Depending on how Mooz is oriented, you can either go for cost-effectiveness in your printing, precision and stability, or speed and color-mixing.What is color-mixing, you ask?
A strong advocate for STEM education, particularly for females, Zuckerberg has firsthand experienced being an outlier — she describes how, in her early days in Silicon Valley, she was often the only woman in a room full of tech executives or investors.She’s since launched a slew of endeavors, including a book and TV show, aimed at getting young girls interested in science or technology.True to form, when it came time for her to pick a location for her latest education-focused venture, she looked beyond the traditional tech coasts.With stations that used edible treats for 3D-printing, coding, and playing with liquid nitrogen, families at the pop-up would be able to get their hands dirty with food, all in the name of exploring science and technology.Zuckerberg shares more on the importance of exposing children, especially girls, to technology, why she thinks the Southern tech scene is thriving, and what’s next for her sweet pop-up venture.When did you first decide to dedicate your time and many of your passion projects to closing that gap?
"Although the 3D scanning technology has made significant progress in recent years, it is still a challenge to capture the geometry and shape of a real object digitally and automatically," explains Mario Fritz, who leads the group "Scalable Learning and Perception" at the Max Planck Institute for Informatics.According to Fritz, depth sensors, such as those of the Microsoft Kinect, are very powerful, but unfortunately they do not work equally well on all materials, which leads to noisy data or even missing measurements."The resulting flawed or even incomplete 3D geometries then pose a real problem for a range of applications, for example in virtual or augmented reality, working together with robots, or 3D printing," explains Mario Fritz.Together with other researchers from the US semiconductor manufacturer Intel as well as the Intel Visual Computing Institute at Saarland University, he therefore developed a method that also works with incomplete datasets.In this way, the researchers could, for example, reconstruct a flat monitor, whose digital representation after a 3D scan looked rather like a paneled wall, so that everyone could once again recognize a monitor in the digital object.The Saarbrücken computer scientists have thereby surpassed previous methods that improve faulty 3D scans and complete digital shapes.

The K-Pan is a 3D-printed camera that uses 120mm medium-format film to capture panoramic photos — with a little DIY thrown in, too.Designed by London-based photographer Paul Kohlhaussen, the K-Pan is launching on Kickstarter with fully assembled editions and DIY kits.Kohlhaussen built the K-Pan for his design portfolio last year, but the initial project reviewed such a large response that he decided to being the K-Pan to more users by launching the camera on Kickstarter.The K-Pan is selling largely as a DIY kit, shipping with the 3D-printed parts, but requiring assembly and allowing for users to apply a custom finish or leave the gray nylon material unfinished.Because the K-Pan is 3D printed, the camera is designed to be a modular system, which means new features can be added and printed at home.While the initial parts are 3D printed and shipped to maintain quality, the developer plans to release updates by sharing 3D printing files and allowing users to print their own expandable accessories.
When there’s a problem in the brain, it pays to be precise — every millimeter counts with something like a tumor or blocked artery.But it can be extremely difficult to understand the exact shape and size of these things, which makes them difficult to diagnose and treat, as well.That’s the suggestion made by Dr. Darin Okuda (above), who recently published some work showing the effectiveness of this printing method in diagnosing and understanding brain lesions found in multiple sclerosis patients.Okuda’s team analyzed MRI scans of MS-affected brains and printed exact copies of the lesions, or damaged areas, detected in them.These were given to people who would normally have just used 2D images or a 3D reconstruction on a screen to diagnose or monitor this type of thing.“By studying lesions in 3D, we are looking at these findings in an entirely different way, assessing their shape and surface characteristics.”

The RNV is making detailed 3D scans of their all ships so that they can carry out fixes and repairs quickly.The Royal Netherlands Navy (RNV) is making detailed 3D scans of all their warships so that they can fix and make repairs faster.According to a Popular Mechanics report, all of the 32 ships and six frigates of the RNV will be scanned in detail.While there is no reported timetable within which the scanning needs to be completed, it is said that the work will be closely watched by other armies around the world to study the viability.One of the uses of 3D scanning ships, says the report, will be the ability to use digital models to 3D print spares and other parts quickly.Some parts that need repair and replacement might not come with ready-to-use 3D models or manufacturing blueprints, so without this tech, such repairs could take weeks to undertake, says Ben Jansen, CNC coordinator at Marinebedrijf Koninklijke Marine, the company that maintains the RNV fleet.
A 3D-printing machine that can be used to create an untraceable metal firearm known as a 'Ghost Gun' has raised fears from authorities as it could allow anyone access to a handgun without any serial numbers, making it almost impossible to be tracked if used.It is not the first time the controversial Ghost Gunner milling machine has been able to create a 'Ghost Gun' but now it can be programmed to carve out the metal frame of a handgun instead of plastic in just under an hour.Its creator is gun rights advocate Cody Wilson – the same person who created the world's first fully 3D-printed gun in 2013 from his Defense Distributed company.Wilson has released new software for the tabletop $1,500 milling machine, which can create three-dimensional objects, and in this instance the Ghost Gunner can precisely shape a piece of aluminium to form the chassis of a semi-automatic pistol.The rest of the DIY gun kit such as firing pin, barrel and slide can be easily purchased online anonymously and assembled at home to create a firearm with no traceable serial number leaving authorities in the dark.This means anybody who purchases the machine could potentially own a lethal weapon, regardless of age bypassing background checks, criminal history and mental health scrutiny.

The next day, tech leaders including Amazon, Facebook, Google, Microsoft, and Salesforce added another $300 million to the bag, spread over five years.The goal of that initiative is to support K–12 STEM education, focusing on computer science.Software and computers drive the economy, aiding mines and farms, as well as retail stores, banks, and healthcare.That’s more than 10 times the number of students who graduated with computer science degrees last year, according to the nonprofit Code.org, which has been working tirelessly to establish and expand CS access in schools.Yet fewer than half of American K–12 schools offer computer science classes, according to Code.org.That number goes up to around three-fourths of K–12 schools when you include CS exposure through after-school activities and clubs, according to a 2016 Google-Gallup report.
Three years ago, Cody Wilson and his organization, Defense Distributed, released a $1,200 computer-numerically-controlled (CNC) mill called the Ghost Gunner.The machine essentially made home gunsmithing faster, cheaper, and more portable than ever before, but it had a limited scope (no pun intended).Initially, the Ghost Gunner only aimed (OK, maybe some pun intended) to complete unfinished lower receivers for AR-15 semi-automatic rifles.“What we’ve done for ARs we’re going to do for handguns now,” Wilson tells Ars.Defense Distributed's store now carries new fixtures, frames, and tooling to create these two handguns, in addition to its previously offered AR-15 lower receivers and jig sets."It’s a certain type of person who builds and enjoys an AR-15—that’s a lot of gun, and most people don’t feel the need to have a big ol’ battle rifle," Wilson says.
