Got an industrial-grade 3D printer laying around that you don't know what to do with? 3D print your own "invisibility cloak"!

We recently told you about how it's possible to 3D print a handgun. Now, a new study shows you can even 3D print an invisibility cloak.

But there are a couple of caveats: the object is still pretty small and it only makes things invisible to microwaves. At east for now. The researchers think the technique could be used to 3D print larger cloaks for visible light in the future.

It's not a gun, but okay. An invisibility cloak is something I could use. Wait, it only makes me invisible to microwaves? Well, I guess that works for when they get to the frozen burrito section of "To Serve Man".
