Metallic Materials Used for Additive Manufacture

Chapter: SECTION C: TECHNICAL REGULATIONS

In Simple Terms

F1 teams can use 3D printing (additive manufacture) to create certain metal parts for their cars. The allowed metals include aluminum alloys, titanium alloys, steel alloys, and copper-based superalloys. However, the final printed part must weigh at least 60% of its original printed form—meaning teams can't remove too much material after printing.

  • 3D printing is permitted for specific metallic materials in F1 car construction
  • Approved materials include aluminum, titanium, steel, and copper/superalloy variants
  • Finished component must retain minimum 60% of the printed mass—material removal is limited
  • Teams must use FIA-approved alloy specifications (e.g., Ti6Al4V, 316 steel, AlSi10Mg)
Official FIA Text

Additive manufacture: Aluminium alloys (AlSi10Mg, AlSi7Mg, etc), Aluminium-Magnesium alloys, Titanium alloys (Grade 1/2, Ti6Al4V, Ti5553, Ti6242), Steel alloys (316, 304, 15-5PH, 17-4PH), Copper/Superalloys. Finished mass minimum 60% of printed component.
