3D printing vs injection molding for small batches

Injection molding is excellent at very high volumes, but for small batches tooling cost and lead time can make the business case weak.

Summary

Injection molding is excellent at very high volumes, but for small batches tooling cost and lead time can make the business case weak.

  • FDM requires no injection mold.
  • FDM can start once CAD and material choice are clear.
  • Design changes are easier between batches.
  • Injection molding often wins once volume is high enough.
