of the false banana, and archaeology's sexual revolution. Here are some of the cool things

from the news today. From 3D bioprinting organs to 3D food printing of alternative meats, the 3D printing world is really on fire right now, with lots of promise for big innovations in the coming years.

But there's another type of 3D printing that could have huge impacts on manufacturing, metal 3D printing. Now, when a lot of people think of 3D printing that could have huge impacts on manufacturing. Metal 3D printing. Now, when a lot of

people think of 3D printing, they think of plastic items printed layer by layer from a digital
