Three-dimensional printing is tough. That is, if you don’t make one out of LEGOs. Gene Hacker posted his creation on Instructables: a 3-D printer made out of LEGO bricks. It’s still in its infancy of development but is more than capable of rendering 3-D blobs of frosting.

Unlike regular Cartesian system printers, the one Gene built operates in polar coordinates, in other words, a circular motion of printing. When asked why he didn’t build a Cartesian system printer (similar to the LEGO scanner), he replied,

“I didn’t have enough LEGOs to build a Cartesian printer.”

Now, that’s funny.

We have seen our fair share of cool geeky cakes, but this is the first one we have seen that comes with a tutorial to actually make it yourself. This Rubik Cube Cake is truly as cool as the arctic tundra. Just plain geek-o-rific.

Using some skilled frosting cutting and lots of strategically placed food coloring, you to can win your next annual geek cake bake off competition. And if that actually exists, please inform us. We would love to take part. — Andrew Dobrow
