FDM 3D printing vs CNC machining for plastic parts

CNC plastic is excellent for tight tolerances and certain materials. FDM can be faster and cheaper when geometry and requirements fit.

Summary

CNC plastic is excellent for tight tolerances and certain materials. FDM can be faster and cheaper when geometry and requirements fit.

  • Choose CNC when tolerances, surface and material certification dominate.
  • Choose FDM for custom geometry, fast iteration, fixtures and low-volume production.
  • Hybrid thinking is often best: print what should be printed, machine what must be machined.

Process

From CAD to repeatable production

1

Send files

CAD, drawing, photo or a short functional description.

2

Technical review

We review printability, material, orientation and risk.

3

Production

The batch is produced with repeatable parameters.

4

Re-ordering

Approved parts can get an article ID for faster repeat orders.

Common questions

Answers that move the project forward

Can you recommend the right process?

Yes. Upload the file and requirements and we will tell you when FDM is a good fit and when another process is better.

Is FDM always the cheapest?

No. Price depends on geometry, quantity, material and quality requirements.

Can the same design move to another process later?

Often yes, but DFM rules differ. Early review helps avoid unnecessary redesign.
