3D printers could revolutionize manufacturing and usher in a new era of Make-It-Yourself. You name it, a 3D printer can probably make it: a belt buckle, a missing Duplo connector -- even a burrito! But what are the limits? How close can we get to Star Trek's replicators?

 

Check out the photo gallery above to see just how wide a range of products these gadgets can produce. Then, take our quiz to test how well you know the capabilities and limits of current 3D printing technology. We'll show you a few objects that were 3D printed along with a few red herrings we threw in. Can you figure out what was printed and what wasn't?

Have you dabbled in 3D printing? We want to see what you've made. Send a photo of your masterpiece to photos@sciencefriday.com and we'll post it online for other SciFri fans to admire.
