Researchers aiming to make buildings much safer during natural disasters have revealed 3D-printed concrete that gets stronger when cracked. As the old saying goes, ‘what doesn’t kill you makes you stronger’, and when it comes to the latest concrete design, that couldn’t be closer to the truth. In a paper published to the journal Advanced Materials, a team from Purdue University in the US revealed an advanced 3D-printed concrete paste designed to actually become stronger when it starts to crack. The new material drew inspiration from nature, specifically the shell of arthropods such as lobsters and beetles that get tougher...

Scientists from Carnegie Mellon University (CMU), Pennsylvania, have used a novel 3D bioprinting method to build functional parts of the human heart. According to a study published in Science, an advanced version of Freeform Reversible Embedding of Suspended Hydrogels (FRESH) technology was developed to 3D print collagen for small blood vessels, valves, and beating ventricles. FRESH technology is patented to FluidForm, a Massachusetts-based medical startup. Professor Adam Feinberg, CTO and co-founder, FluidForm, and Principal Investigator at the Regenerative Biomaterials and Therapeutics Group, CMU, said: “We now have the ability to build constructs that recapitulate key structural, mechanical, and biological properties...

Cobod is ready to ship the world’s largest 3D construction printer to Elite for Construction & Development Co in Saudi Arabia – ordered as part of the kingdom’s Vision 2030 mandate to build 1.5 million private-sector homes over the next 10 years – after completing the dry and full testing of the printer, a machine that offers a print area of 300m2 per floor and can print three-floor tall buildings, with its Bod 2 configuration marking the largest that Cobod has produced to date. After a private house in Riyadh was 3D-printed last year, multiple public and private organisations have...

I have long suggested practical homemade guns of the future will only use 3D printing as part of the process. They will be hybrid designs using the strengths of 3D printing and simple metal components to produce practical firearms in the home or in small, unregulated shops.A prominent experimenter of homemade and small shop technology for crafting usable guns, Ivan the Troll (Internet screen name) claims to have made a breakthrough in home manufacture of rifled barrels. Ivan is part of, and often the spokesperson for, the Deterrence Dispensed project. Rifling a barrel has been done for hundreds of...

Scientists were faced with the unique challenges of creating a technique that would still work in zero gravity. So, the team invented a method of 3D printing that would work while upside down. They thickened human blood plasma, which is used to bioprint skin cells, with plant material so it could work in altered gravity. To 3D print bones, they added calcium phosphate bone cement to printed human stem cells. The calcium phosphate works as a structure-supporting material, and is absorbed by the body as the bone grows. The samples are just the first steps in a long journey to...

A young man from Zimbabwe has been convicted in London of making and possessing two guns with a 3D printer. The gun parts were discovered during a raid searching for marijuana. From independent.co.uk: A second raid of his home in February 2018 led to the discovery of further components of another 3D printed gun.Acting Detective Sergeant Jonathan Roberts, who led the investigation, said: “We know that Muswere was planning to line the printed firearms with steel tubes in order to make a barrel capable of firing.“This conviction, which I believe is the first of its kind relating to the...

Tomorrow is the day. The AR-15 will be unleashed to circulate on the Internet forever. When the day of home 3D metal printing arrives every free citizen of the world will be able to make one. This is the nightmare for oppressors - but a blessing for the liberty loving common man.

All 3D printing tends to get lumped together, but there are actually two specific styles with some pretty significant distinctions. Fused deposition modeling (FDM) is a faster, but less accurate, method achieved by layering melted plastic into a shape. Stereolithography, (SLA), sacrifices speed for precision by using an ultraviolet laser to harden a liquid resin. That trade-off limited 3D printing’s potential: You could either slowly print actually useful parts and objects, or rapidly print mostly useless trinkets. But thanks to a recent breakthrough from tag team of researchers, SLA has now become equally as fast as its counterpart. Before this...

When you walk around a Maker Faire, you’re likely to see a wide variety of 3D printers, though if you look at the basic construction, you’ll find there are usually only two main types on people’s tables. There are cartesian (with a gantry at right angles) and delta (the ones with three arms holding the print head). Sure, there are a few others that appear from time to time, but these two dominate the landscape. Cel-Robox has teamed up with M-Solv to create a new entity called Q5D Technologies to push new manufacturing technologies, such as this one that caught...

Printer company Dagoma and TBWA Paris edited the files to make the firearms useless In 2013, Second Amendment activists briefly released online blueprints for 3D-printed guns, firearms made of plastic that can be fabricated by relatively inexpensive consumer-level machines and assembled to shoot real bullets. The Defense Department shut down the distribution, but last year, the blueprints were made public again after a lawsuit. Despite ongoing legal wrangling and court-issued injunctions, gun blueprints were downloaded at least 20,000 times. The cat is out of the bag, and there’s no way to put it back in. But maybe the cat can...

Capitol Police on October 3 arrested 27-year old congressional staffer Jackson Cosko for posting on Wikipedia the private addresses of three members of the Senate Judiciary Committee—what’s known as “doxxing” (a word derived from the shorthand for “document”). Cosko is facing serious charges that include illegally posting private information of public figures, witness tampering, threats, identity theft, and unlawful entry. In the mainstream media, Cosko is being portrayed as a hapless overzealous intern who didn’t even have the smarts to cover up his criminal act. His former boss— Rep. Sheila Jackson-Lee (D-Texas) has denied she knew anything about Cosko’s activities....

Humans have figured out lots of ways to shape metal -- casting it with a mold, stamping it, drilling holes and milling surfaces in a machine shop, even zapping it with a laser. Well, now you can add a new method: 3D printing. A number of companies offer metal 3D printing, which creates products and components layer by layer with a computer-controlled system tracing its lineage to ordinary inkjet printers. But on Monday, printing giant HP announced it's entered the market with the ambition to dramatically lower prices, courtesy of a $400,000 product called the Metal Jet. "We're really going...

AUSTIN — Cody Wilson, the Austin man who owns controversial 3D-printed gun company Defense Distributed, has been accused of sexually assaulting a child, an affidavit obtained by KVUE reveals. During a forensic interview with the Center with Child Protection on Aug. 27, the victim told counselors she met Wilson through the website, SugarDaddyMeet.com. Court documents show Wilson used the profile, "Sanjuro," and told the victim that he was a "big deal." During the conversation, he also identified himself as "Cody Wilson." Police said the two exchanged cell phone numbers and continued their conversations using the Apple iMessage service on her...

We’ve seen 3D-printed houses, ceilings, and bridges. But one of the most sensible uses for the technology may be by the U.S. Marine Corps, which recently finished printing the world’s first 3D-printed concrete barracks. The new technique is safer and less wasteful compared to conventional construction methods–and the research, a collaboration with the architectural firm SOM, could change how emergency housing and infrastructure are built, too. “The clearest advantage is flexibility,” Captain Matt Friedell, the Additive Manufacturing Lead at the Marine Corps Systems Command, headquartered in Quantico, Virginia, says over email. “We can make walls, obstacles, buildings, and other structures...
