Using a machine to print an object from scratch may sound like something out of a sci-fi novel, but the concept has actually been around for more than 30 years. As 3D technology continues to evolve and become more accessible (it even has its own category on Amazon), the possibilities of what it can do are seemingly endless.

Here are 10 cool things already being printed in 3D — and no, none of them are guns.

1. Food

One of the most magical parts of the Harry Potter series — for food lovers, anyway — was how the food served at Hogwarts’ Start-of-Term feast automatically replenished itself. With 3D printing, it’s now possible to do almost exactly that. NASA was one of the first to jump on board, funding the development of a fully functional 3D food printer in order to feed astronauts in space.

Now it seems like 3D-printed food is everywhere. Even students like Marko Manriquez, maker of the Burrit0bot, are coming up with new treats to print.

2. Soil

Printing dirt may not sound very cool at first, but as Professor Wilfred Otten explains, “What we often forget is that everything above ground relies on the soil it stands on — it plays a major role in food security and the carbon cycle.” Scientists at the UK’s Albertay University have begun printing intricate 3D images of soil structures in order to better understand the ways in which fungi and bacteria interact within them.

3. Crime scenes

Real-world crime-scene analysis isn’t exactly the fast-paced, high-tech drama shown on TV. However, that could change soon — at least, the high-tech part. A police department in Roswell, New Mexico, recently acquired a Faro 3D scanner capable of creating both digitized, panoramic views and small-scale models of crime scenes. This technology can help law enforcement and investigators improve their ability to analyze a scene and display it to juries in the courtroom.
