A Subtractive 3D Printer

Name of Model: LEGO 3D Milling Machine - "3D Printer"

This "milling machine" is an unusual approach to the 3D Printer concept - instead of using an additive process that slowly stacks up, this machine uses a subtractive process by taking a block of floral foam and trimming it down. That "trimming" is actually even more interesting - a drill (the only non-LEGO component here) digs in over and over again, and the final shape of the printed object is only visible after using a vacuum cleaner to suck away the thick layer of floral foam dust.

actually, not really that unusual... Its called a CNC milling machine. They've been around for many years, much longer than 3d printers that lay material down.

Subtractive 3d printing is not a thing. That's called milling...
