Manufacturing with 3D Printers and CNC Mills

In This Chapter

  • How 3D printers work
  • The workings of CNC mills
  • Should you use a 3D printer or a CNC mill?

When it comes to rapid prototyping, there are generally two approaches that can be taken: 3D printing and computer numerical control (CNC) milling. CNC milling isn’t strictly considered “rapid prototyping,” but that’s mostly a matter of semantics. In practice, CNC mills can create 3D parts just like a 3D printer, and can often do it more quickly and with greater precision.

However, CNC mills and 3D printers differ greatly in their actual operation. Essentially, they’re two completely ...
