3D printers work by laying down material, a process called additive manufacturing. Computer Numerically Controlled milling machines (CNC mills) work by removing material, which is subtractive manufacturing.
CNC mills aren’t quite as sexy as 3D printers, perhaps because the technology has been around a bit longer. Nevertheless, both technologies are useful and, indeed, complimentary.
A small company in Arkansas has recognized that fact and developed the first desktop manufacturing machine that does both addition and subtractive manufacturing. The Quintessential Universal Building Device, or QU-BD, will be introduced at Maker Faire in San Mateo.
Just one of the many wonders to be found at Maker Faire. See you there!
