"CNC" stands for "Computer Numerically Controlled," and CNC Fabrication means "using computers to control machines to make stuff."
By using software to control hardware, we can easily turn our ideas into physical objects, test them, tweak them, and try again. This is called "Rapid Prototyping," and is the foundation of contemporary design.
The Maker Hubs CNC machines include 3D printers, a Laser Cutter, and a Vinyl Cutter. Each machine is best suited for different types of fabrication. Take a look at the pages for individual machines to learn more.
