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.

When NASA gets really bored, it starts doing pointless comparisons of the first successful landing on the moon. Only the brightest minds at NASA will be jotting down coordinates and tracing all of Neil Armstrong and Buzz Aldrin’s movements. It turns out that the two original mooninites only hopped around in an area smaller than a soccer field.

So NASA: Interplanetary exploration? We care. Beer in space? We care. Your old missions compared to modern day sports? Don’t care. Figure out space travel instead of wasting time dwelling in the past. Unless of course, dwelling in the past eventually leads to innovative space traveling techniques that lead to the creation of sports in space.
