3D Printing Gun Out of Lego

What do you do if you want to 3D print in any direction, but can’t buy a pre-made pen like the 3Doodler? If you’re Vimal Patel, you build your own. He melded a hot glue gun with a powered Lego mechanism (really, Technic) to extrude filament in any axis. To call it bulky would be an understatement, but it works — as you’ll see in the video below, it can produce fairly complex objects as long as you have a keen eye and a steady hand. And if you want to try it, you can. Patel has posted his Lego Digital Designer file for the 3D printing gun, so it shouldn’t be too hard to replicate the invention at home.

3Doodler: The World’s First 3D Printing Pen

If anyone hasn’t already seen this, it is the 3Doodler. It is the world’s first and only 3D Printing Pen. Using ABS plastic (the material used by many 3D printers), 3Doodler draws in the air or on surfaces. It’s compact and easy to use, and requires no software or computers. You just plug it into a power socket and can start drawing anything within minutes.
