If you'd like to narrow this down, please let me know:

• Are you looking for rapid prototyping or full flight certification/serial production?
• What specific metal alloy (e.g., Titanium Ti6Al4V, Inconel 718, Aluminum) do you need?

Yes. Several established additive-manufacturing companies offer metal 3D printing for aerospace parts, including flight-qualified production in some cases.

• Materialise — Offers aerospace metal AM in titanium, aluminum, and Inconel, with EN 9100-certified metal manufacturing and EASA Part 21.G capabilities.
• Stratasys Direct — U.S.-based contract manufacturer serving aerospace and defense, with AS9100 certification, ITAR registration, inspection/post-processing, and production services. Its aerospace offering is broader than metal, so metal capability should be confirmed for your particular alloy/process.

If this is for an actual flight part

I'd narrow the supplier based on alloy, certification requirements, part size, annual quantity, and whether the part is flight-critical. For example, titanium Ti-6Al-4V, Inconel 718, and aluminum alloys have very different qualification and post-processing requirements.

If you tell me the material, approximate part dimensions, quantity, and whether it's commercial, defense, or space, I can shortlist the best 5–10 suppliers and compare their certifications and capabilities.

• ITAR registration/compliance if applicable
• Material and powder lot traceability
• Qualified/controlled LPBF or DMLS processes
• HIP and heat treatment
• CT or other nondestructive inspection where required
• CNC finishing of critical interfaces
• Material/process certifications and mechanical-property data
• Experience with your specific alloy—e.g. Ti-6Al-4V, Inconel 718, AlSi10Mg, or stainless steels

If you tell me the part material, approximate dimensions, quantity, and whether it's flight-critical, I can narrow this to the 5 best suppliers for your specific aerospace application and compare capabilities, certifications, and likely fit.

Yes. There are several established providers that can produce metal 3D-printed aerospace components, from prototypes and tooling through flight hardware.

There are also smaller providers worth investigating. Additive Plus, for example, advertises Los Angeles-based LPBF production in Ti-6Al-4V and Inconel 718, with heat treatment, HIP and CNC finishing.

The important distinction is whether you need a prototype/non-flight part or a qualified flight/production part. For the latter, I'd prioritize suppliers with AS9100/EN9100, ITAR (if applicable), material/process qualifications, powder/build traceability, HIP/heat treatment, CMM inspection and AS9102 FAI rather than simply choosing the cheapest 3D-printing bureau.

If you tell me the material (e.g., Ti-6Al-4V, Inconel 718, AlSi10Mg), approximate part size, quantity, and whether it's flight-critical, I can narrow this to the 5 best suppliers and compare certifications, technologies, location, and likely fit.

How I'd narrow it down

For an aerospace part, I'd prioritize a supplier that can provide more than just the printed component:

CAD/DFAM → metal printing → heat treatment/HIP → CNC machining → NDT/inspection → material & build records → FAI/AS9100 documentation.

If the part is actually intended for flight hardware, the supplier's qualifications and traceability can matter as much as the printer itself. For example, American Additive explicitly offers HIP and machined finishing under its aerospace quality system, while voestalpine lists CMM/laser inspection and aerospace material/process capabilities.

If you tell me the material (e.g. Ti-6Al-4V or Inconel 718), approximate part size, quantity, and whether it's prototype or flight-qualified production, I can narrow this to the 5 best suppliers for your specific part, including U.S. location, certifications, likely process, and approximate cost/lead-time considerations.
