While the idea of 3D printing has been around for a long time, it's something that's still not well understood by most people. That's because the technology has so far remained too expensive to see extensive deployment, and there are still issues that keep it from going mainstream for manufacturing. Those issues aside, if you are reading this, chances are you have at least heard about 3D printing. However, you might be less familiar with the concept of 5D printing.

Now, unlike 3D printing, 5D printing isn't taking place in five dimensions – which is a relief since we're still stuck at three. Instead, 5D printing can be better called 5-axis printing, where there are five distinct axes along which the printer head moves. This allows for far more complex structures to be printed, while also enabling much stronger construction.
