This is NASA's new "space fabric" in development at the Jet Propulsion Laboratory.
The metal textile is 3D printed in one piece yet can be easily folded and flexed. Eventually, the researchers expect that such materials could be used as deployable shields to protect spacecrafts from meteorites, as insulation, or possibly for new kinds of spacesuits. To my eye, it could also lead to some fantastic fashions at the cosmic disco. From NASA JPL:
A technique called additive manufacturing, otherwise known as 3-D printing on an industrial scale, is necessary to make such fabrics. Unlike traditional manufacturing techniques, in which parts are welded together, additive manufacturing deposits material in layers to build up the desired object. This reduces the cost and increases the ability to create unique materials.
"We call it '4-D printing' because we can print both the geometry and the function of these materials," said Polit Casillas. "If 20th Century manufacturing was driven by mass production, then this is the mass production of functions..."
The space fabrics have four essential functions: reflectivity, passive heat management, foldability and tensile strength. One side of the fabric reflects light, while the other absorbs it, acting as a means of thermal control. It can fold in many different ways and adapt to shapes while still being able to sustain the force of pulling on it.
The JPL team not only wants to try out these fabrics in space someday, they want to be able to manufacture them in space, too.

Way back in 2011, major American automakers were slow to realize that “companies in Silicon Valley have for some time been looking at cars just like another mobile device or app.” When the disruption, hit, it hit hard, writes Nick Bilton:
Founded in 1970 as Xerox’s R&D division, PARC was a dream factory that brought the world laser printing, Ethernet, the graphical user interface that led to Windows and the Macintosh, ubiquitous computing, and many other technologies that we now take for granted. Why made the place so damn special? Alan Kay, who pioneered networked computing […]
For robots to make our lives easier, they’ll need to work together. But how do we teach them teamwork? University of Southern California engineer Nora Ayanian studies how groups of robots, including flying drones, can be better collaborators and what the machines can teach humans about collaboration. Mark Frauenfelder and I interviewed Nora about robot […]
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
