A standard bedslinger...but with a twist! The frame, motion system, and extruder are made out of 92%1 LEGO bricks.
This project started as a response to a Hack Club YSWS called Infill. The challenge was to build a 3D printer for under $350, with a twist. Having grown up with LEGO, I decided to make the entire printer out of it.
To make this printer truly one of a kind, I took it a step further: not only would it be built from LEGO, but I would also use only classical LEGO bricks2 wherever possible. As you might expect, some parts, especially the custom mounts for steppers, electronics, and other hardware, can't realistically be made under that limitation.
LEGO cost will vary depending on local availability, and the BOM cost is only a rough estimate. Prices in the sheet reflect the time it was created and are not guaranteed to stay the same. Some parts may also go out of stock, since this BOM will not be actively maintained.
