OK, almost entirely: The actual cutting is done by a metal drill bit. Everything else, however, is Lego system elements. It looks like the machine uses a “raster” type subtractive process, covering the surface of a florist’s foam block in a close-packed grid of holes, each of which is drilled to an appropriate depth to form the final surface contours. It doesn’t look like it works at all, until maker Arthur Sacek turns on the hair drier to blow away the chaff. Then the magic happens. [via The Brothers Brick]

    From the video, he actually sucks it up with a vaccuum cleaner, but close enough ;-)

    Is floral foam any good for making a cast? Is it to brittle or porous?

      Both. But, if it works on floral foam you might be able to build one that cuts plaster or something a little tougher.

    wow! this is amazing how would you able to made this without a machine? because I’m looking or a good milling machine that will last longer, durable but cheap price.
