We've come across our fair share of 3D printers here at Tom's Hardware. We've even covered a handful of clever Lego-based projects. This is the first time, however, we've seen the two meld together so harmoniously. In a fascinating display of intellectual finesse, a maker who goes by Zealousideal-Army333 over at Reddit has created a working 3D printer using Lego bricks.
Most people would rather buy a printer and get busy printing, but Zealousideal-Army333 truly channeled their inner maker when coming up with this idea. The entire 3D printer body was put together from scratch and, being an original idea, this inevitably took a look time to complete, as confirmed by Zealousideal-Army333 in the original project thread.
Surely you're wondering how well a Lego-based 3D printer performs. The answer? It's fantastically terrible. Sure, you can print a Benchy but it's going to take several tries and the patience of a saint to see it through. Let's say that you're willing to see past those shortcomings for the delightful novelty of a Lego 3D printer—be ready to fork out plenty of cash. You're going to spend almost twice as much as you would on something like an Ender (the Ender 3 V3 is one of our favorites). This project requires more than just Lego bricks, you'll need motors, gears, technic frames, a 3D printing pen and more.
Overall, this project is incredibly cool and it's amazing to see it in action. Still, we recommend anyone interested in 3D printing snag a 3D printer for themselves rather than build one out of Lego bricks.
