Very interesting but they didnt actually say how they made the non-weldable metal, weldable. Would be interested to know what it is they actually did.

- tyingq 9y agoThis article has more detail. https://www.seeker.com/tech/materials/nanoparticles-keep-3d-printed-alloys-from-cracking https://www.seeker.com/tech/materials/nanoparticles-keep-3d-... "They used a computer program to sort through and analyze more than 4,500 different alloy and nanoparticle combinations to see which ones had atomic structures that would fit together best. The idea was that the grains of metal would glom onto the tiny nanoparticles, sort of like a water vapor droplet that nucleates around a particle of dust to create a drop of rain. They found that a nanoparticle made of hydrogen-stabilized zirconium would work best with two different kinds of aluminum alloys."

- hugs 9y agoUsually when key information (like price, but also sometimes key tech) is left out, it's because they want you to contact them so they can begin the formal sales process. In this case, though, since there is a Nature [1] article about their technique, the details just didn't make it into the Futurism article.
