Gallery: Incredible LEGO Printer Invented by 14-Year-Old Boy!


We’ve seen LEGO wizards create some pretty amazing projects lately by combining the iconic blocks with technology. One fourteen year old LEGO genius, Leon Overweel, has used his skills to construct his very own LEGO printer! Dubbed the LEGO Mindstorms NXT printer (or PriNXT), the machine uses three motors to control an attached pen, which draws objects and messages.

    I could swear blind that something like this was one of the original projects for the old Lego Control Centre of the early 90s. You could hook the thing up to a BBC Micro and use it as a plotter… Ages 12+ I think.

    And then there was the “Lego Inkjet” of a couple years ago where someone on youtube made up an actual line-printer (rather than plotter) using a felt pen that could be hooked up to a mac and controlled with a custom driver. Replete with minifigs “operating” the machinery.

    It’s a pretty cool thing this kid has made, but it’s hardly an invention.

    BTW, Johnross – no… what you want is a LEGO Reprap… O_O

    Very cool – can you post any of the printed images so that we can see what they look like?

    Hey this is Leon :) Thanks for the awesome article!! Just one thing: my last name is without the “h”. It’s a common problem, so don’t worry about it, but if you could change it that’d rock :)

    Thank you!
