3D Printing vs CNC Machining: How to Choose

Additive or subtractive? 3D printing and CNC machining both make great parts — they’re just good at different things. Here’s how to decide.

When 3D printing wins

  • Complex geometry, internal features or organic shapes.
  • Fast, low-cost prototypes and iterations.
  • Lightweighting and consolidated assemblies.

When CNC wins

  • Metal parts and very tight tolerances.
  • Specific surface finishes and material certifications.
  • Simple geometries in higher volumes.

Often the smart move is to combine them — print a prototype to validate, then machine the production version. Cost is usually the deciding factor; see how much 3D printing costs. For ongoing runs, weigh low-volume production options too.

Tell us about your part and we’ll recommend printing, machining, or both.
