Credit: SciTechDaily.com ================================================================================== AI-driven research is making titanium 3D-printing faster, stronger, and more efficient, transforming aerospace and defense manufacturing. Producing high-performance titanium alloy parts—whether for spacecraft, submarines, or medical devices—has traditionally been a slow and resource-intensive process. Even with advanced metal 3D printing, determining optimal manufacturing conditions has required extensive trial and error. But what if these parts could be made faster, stronger, and with near-perfect precision? A research team from the Johns Hopkins Applied Physics...

More effective and sustainable firearms are on the horizon — but future technology is now banned before it can even come to fruition. For 63 years, the United States Congress has drafted and passed the National Defense Authorization Act. The purpose of this act: to pass the country’s defense budget for the following fiscal year. While Americans are focused on inflation and other trending topics, this bill passes every year under the radar. It’s Congress’s way of slowly chipping away at the constitutional rights of millions of Americans without any pushback — mainly because people don’t know about it. However,...

From his Illinois home, he champions guns for all. The Times confirmed his real name and linked the firearm he helped design to terrorists, drug dealers and freedom fighters in at least 15 countries.After an attempted gang murder in the French city of Marseille last year, the police found what appeared to be a toy assault rifle, seemingly crafted from plastic and Lego parts. “But the weapon was lethal,” Col. Hervé Pétry of the national gendarmerie recalled. In the past three years, this model of homemade semiautomatic firearm, known as an FGC-9, has appeared in the hands of paramilitaries in...

Using lasers and metal powder, Australian scientists have created a super strong, super lightweight new “metamaterial” — but they got the idea for this sci fi-sounding creation from plants. The challenge: Materials that are strong yet lightweight, such as carbon fiber and graphene, are used to make everything from medical implants to airships, and developing ones with ever greater “strength-to-weight ratios” is the goal of many material scientists. In pursuit of that goal, some have turned to nature, looking for ways to replicate in metal the hollow lattice structures, like those in the Victoria water lily, that make some plants...

A groundbreaking project has emerged in Heidelberg, Germany, which has welded architecture and technology together to create something that has never been done before. The nation has built Europe's largest 3D-printed building known as the Wave House, according to COBOD. The new structure is reportedly a data center. The report mentioned that data centers are the backbone of today's digital world, but the buildings are often reduced to windowless buildings for security and operational reasons. However, the push to bring these infrastructures into urban areas has forced designers to rethink their design approach. And it took COBOD just 140 hours...

“This project can be the beginning of something meaningful.”A California couple is set to move into a one-of-a-kind home later this year that will be resistant to wildfires. According to Highways Today, a robotic arm 3D printer created by RIC Technology began construction in January on the state’s first fire-resistant, 3D-printed concrete accessory dwelling unit in the city of Walnut. The general contractor Builtech Construction Group is leading the design in collaboration with the city of Walnut and the Los Angeles County Fire Department. Philips and Constance, a couple living in Walnut described as “eager to contribute to wildfire protection,”...

Share 3D-printed “superalloy” could make power plants more efficient...Credit: kinwun / Adobe Stock Anew high-performance metal alloy, called a superalloy, could help boost the efficiency of the turbines used in power plants and the aerospace and automotive industries. Created using a 3D printer, the superalloy is composed of a blend of six elements that altogether form a material that’s both lighter and stronger than the standard materials used in conventional turbine machinery. The strong superalloy could help industries cut both costs and carbon emissions — if the approach can be successfully scaled up. The challenge: In the world of materials...

3D-Printed Vegan Meat is Going to Conquer the Competition Ahsan Raza / 05 Jan 2023 / Tech 3D-Printed Vegan Meat If you were to have asked someone back in 2012, what market would have an estimated value of close to U.S. $8 billion in 2022? No one would have guessed that value would be placed on plant-based meat! But according to Business Wire, the global plant-based meat market is today worth a whopping U.S. $7.9 billion and is projected to hit U.S. $15.7 billion by 2027. Like any gold rush, there will be winners and losers in the struggle to...

An upstate New York sheriff is irked that people around the US are 3D printing firearms to turn into gun buyback programs for cold, hard cash. "I know in Utica, New York, Houston, Texas, and Spartanburg, South Carolina that 3D printed guns were submitted to the gun buyback program," Robert Swenszkowski, the sheriff of New York's Oneida County and, strangely, a professor at Utica University, told Spectrum News 1. He appeared to be referring to several stories that emerged this summer, in which people in Texas, South Carolina and New York did indeed sell back guns they 3D printed at...

A TECH-SAVVY New Yorker has made a whopping $21,000 by selling 3D-printed guns.The man, who identified himself as 'Kem', sold 110 guns to the attorney general's office in a buy-back scheme, Futurism reported.Earlier this year, the state of New York started a 'Cash for Guns' program that offers at least $200 to anyone who surrenders a gun. Kem then saw people tweeting about the program while joking that they could 3D-print guns to earn some instant cash.The tweets inspired Kem to try the scheme out in real life, using a $200 3D printer he'd gotten for Christmas."I 3D-printed a bunch...

25-year-old man from Minneapolis has been federally charged for being in possession of and manufacturing auto sears, devices that are used to convert a semi-automatic firearm into a machine gun.The U.S. Attorney for Minnesota, Andrew Luger, says that Aaron Malik Cato had four 3D printers at his residence and was in possession of several 3D-printed auto sears.In addition to the homemade devices, authorities say Cato also possessed the parts to make up to 10 more devices.

"It’s come to our attention that German magazine Der Spiegel reports the inventor of the rapid-fire 3D-printed gun that could be entirely printed at home has passed away. JStark, a 28-year-old German citizen, was one of the biggest innovators of this decade when printing weapons and gun parts at home. He helped create Deterrence Dispensed – an online group that promotes and distributes open-source 3D printed firearms, gun parts, and cartridges. The group strongly supports freedom of speech applied to computer code and blueprints. Der Spiegel says JStark passed away on Friday of an apparent heart attack. Foul play was...

The Netherlands needs thousands of new homes to accommodate its growing population and it might not build them all – some may end up being printed. As part of a program exploring how the country can create the homes it needs, Elize Lutz and Harrie Dekkers have moved into a new 94-square-metre, two-bedroom home that resembles a boulder with windows. The curving lines of its grey concrete walls look and feel natural, but they are actually at the cutting edge of housing construction technology in the Netherlands and around the world. They were 3D printed at a nearby factory. "It's...
