Lego Polar 3D Printer

By on August 29th, 2008 in blog



Yes, it is apparently possible to build a working 3D printer out of Lego blocks! Don’t believe us? Check out the link below to Instructables, where Gene Hacker provides a step-by-step process for creating the device.


Interestingly, he used a Polar coordinate system rather than the traditional XYZ scheme, because “I didn’t have enough Legos to build a Cartesian printer”. As they say, necessity is the mother of invention.

Kerry Stevenson, aka "General Fabb" has written over 8,000 stories on 3D printing at Fabbaloo since he launched the venture in 2007, with an intention to promote and grow the incredible technology of 3D printing across the world. So far, it seems to be working!

  1. Back in March 2001 Elektor Electronics provided an article on a polar based PCB drilling machine. The drilling arm moved on an arc and the PCB was rotated on a table. There was also a clever thin gearing system for moving the table. It had a ratio of 231:1 in just one stage (a stage consisting of 2 gears and 2 annular gears) with 60:22 and 23:63 teeth. ref: VDI 2157
