Description

Hod Lipson and Melba Kurman:

"more established than 3D printers are desktop-sized numerically controlled (CNC) routing and milling machines. These machines use a physical blade to cut and carve precise designs into a broad range of materials. Under the guidance of an electronic design blueprint, a rotating mill bit, sometimes called a cutter, is spun along by a motor called a router or spindle. As the electronic blueprint guides the cutter along x, y and z coordinates, the cutting tool makes multiple passes over the material to create perfectly carved engravings or shapes."

Materials:

"CNC routers and milling machines work with a wide variety of materials, from wax to wood to metal to porcelain. CNC routers and milling machines are capable of manufacturing a broad range of everyday objects and parts, ranging from plastic name plates and printed circuit boards, to complex 3D objects such as airplane parts and kitchen utensils."

Advantages

Hod Lipson and Melba Kurman:

  • "CNC routers and milling

machines work with a wide variety of materials

  • The upside of desktop

routers and milling machines is that they are precise, faster than 3D printers, and work with a larger variety of materials.

  • Since computer-guided CNC routers and

milling machines have been in existence in industry for decades, they enjoy a large variety of available tooling, and a broad and experienced user base.

  • Due to their

speed and precision, CNC routers and milling machines, even small ones, are ideal for creating large batches of items. " (http://web.mae.cornell.edu/lipson/FactoryAtHome.pdf)


Disadvantages

"However, CNC machines are significantly less versatile than 3D printers in the range of shapes they can create." (http://web.mae.cornell.edu/lipson/FactoryAtHome.pdf)
