Researchers have designed and built the world’s first microscope made entirely from 3D-printed parts. And because the open-source plans are already available online, almost anyone can assemble their own for barely $60.

A 3D robot printer can also print larger buildings in one go. This speeds up construction and is more cost-effective.

You can use 3D printing for producing pretty much everything: vegan meat, fancy shoes, or even a wall-climbing robot. NASA's 3D-Printed Habitat Challenge developed a living environment for Mars. So, what about a 3D-printed house on Earth?
