Spinning LEGOs Produce 3-D Blobs

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... Continue reading
