Researchers have that found that 3D printers spew tiny particles into the air as they operate, though the quantity and nature of these potentially toxic aerosols are poorly understood. A new study identifies a startling variety of these emissions, and the conditions under which they’re produced.

After four years aboard the International Space Station (ISS), NASA has confirmed it’s mission complete for phase I and II of the Made In Space operated “3D Printing in Zero G Technology Demonstration.” The findings of this mission, accepted October 2018, were used in development of the Made In Space Additive Manufacturing Facility (AMF) which has been operating aboard the ISS since 2015. With this facility, and the early stage data...

Project Milestone is building the world’s first 3D printed concrete homes that will actually be lived in.

3D Printing is not a new thing to hear about. It is a very popular industry right now that began in the early 80s. But how different is Open Source 3D Printing from proprietary designs? How does this affect its applications in Science and Medicine? Let’s read on.

3D printers have ‘fingerprints,’ a discovery that could help trace 3D-printed guns, counterfeit goods.

This week, during an event at SXSW in Austin, a startup called ICON unveiled an amazing project, a house that could be 3-D printed for just $4,000. With the new method that the company has developed, they are able to print a 650-square-foot house out of cement in less than 24 hours. In contrast, it could take a human roughly 20 days to complete the same project.

3D-printed construction is portable and inexpensive, and could help build a safe barracks in a shorter time. With this in mind, the US Marine Corps Systems Command recently constructed a prototype concrete barracks in under two days with what it says is the world's largest 3D printer.

The local fishermen looked on skeptically. From the deck of a small motorboat, scuba divers grabbed odd chunks of ceramic – which could be described as rocky brains stuck on stumpy stilts – and plunged into the aquamarine waters. The dive team assembled the pieces as a few triggerfish circled around to investigate the commotion.

Amazon has banned a book that provides the code needed to 3D print a handgun. "The Liberator Code Book: An Exercise in the Freedom of Speech," appeared on Amazon's website on August 1. The company said it dropped the $20 book on Wednesday because it violated Amazon's content guidelines, but it would not offer further details.

The founder of an organization that publishes designs for 3D printable guns online said Sunday that he's willing to accept the "social costs" that come with his products in the name of defending the Second Amendment. Cody Wilson, the founder of Defense Distributed, argued on "Fox News Sunday" that any restrictions on the ability to print 3D guns would infringe on First Amendment and Second Amendment rights.

Under a court settlement, people aren't supposed to be able to legally download plans for 3-D printed guns until Wednesday. But because designs for the guns have already been posted online, by Sunday more than 1,000 people had already downloaded plans to print an AR-15-style semiautomatic assault rifle, according to the office of Pennsylvania Attorney General Josh Shapiro.

No traceable gun parts, no background checks, no need for much more than a computer and a 3D printer at home to build one. They could become the firearms of the future: Plastic-and-resin weapons that American gunsmith and self-described anarchist Cody Wilson wants to spread widely. On Aug. 1, the 30-year-old Texan intends to legally distribute online blueprints for his single-shot "Liberator" pistol, as well as manuals to complete guns such as the AR-15.

Gun-rights activists have reached a settlement with the government that will allow them to post 3-D printable gun plans online starting August 1. The settlement ends a multi-year legal battle that started when Cody Wilson, who describes himself as a post-left anarchist, posted plans for a 3-D printed handgun he called "The Liberator" in 2013.

Developers say project will cut costs and environmental damage and offer solution to shortage of bricklayers

A team of researchers from MIT and Harvard University has come up with a way to get 3-D printers to print objects using data sets rather than geometric representations. In their paper published on the open access site Science Advances, the group describes their new technique and some of the ways they believe it could be used.

New York based architecture practice DFA, has proposed a portable 3D printed structure for an elite respite location which caters to a community of wealthy technologists. By Kieron Marchese.

The first human corneas have been 3D printed by scientists at Newcastle University. It means the technique could be used in the future to ensure an unlimited supply of corneas. As the outermost layer of the human eye, the cornea has an important role in focusing vision.

The world’s oldest standing army is getting some new headgear. The Swiss Guards plan to replace their metal helmets with plastic PVC ones made with a 3-D printer, giving the pope’s army cooler and more comfortable headgear when standing guard for hours at a time. The Swiss Guards unveiled the helmet prototype before their annual swearing-in ceremony Sunday. Thirty-two new recruits — all of them single Swiss men under age 30 and upstanding Catholics — will join the small corps for a minimum two years by pledging to protect the pope and his successors.

In a groundbreaking new study, researchers at the University of Minnesota used a customized, low-cost 3D printer to print electronics on a real hand for the first time. The technology could be used by soldiers on the battlefield to print temporary sensors on their bodies to detect chemical or biological agents or solar cells to charge essential electronics.
