Who offers metal 3D printing services for aerospace parts?

Several companies offer metal additive manufacturing (metal 3D printing) for aerospace parts, ranging from rapid prototypes to certified flight hardware. Some notable providers are:

Other aerospace-oriented suppliers include:

• Forge Labs — aerospace additive manufacturing for flight hardware, UAV parts, tooling, and lightweight assemblies.
• Polran Metal — metal AM for aerospace and defense mission-critical parts.

When selecting a supplier, aerospace buyers typically check for:

• AS9100D certification
• ITAR registration (if applicable)
• Metal processes: DMLS/SLM, EBM, WAAM, DED, or binder jetting
• Materials: Ti-6Al-4V, Inconel 718/625, aluminum alloys, stainless steels, cobalt chrome
• Post-processing: HIP, heat treatment, CNC machining, surface finishing
• Inspection: CT scanning, CMM inspection, material traceability, first article inspection (FAI)

For flight-critical aerospace parts, the shortlist is usually narrowed to suppliers with aerospace quality systems and qualification experience rather than general 3D printing bureaus.

Several certified industrial service bureaus and manufacturers offer metal 3D printing (Additive Manufacturing) specifically tailored for flight-ready aerospace parts, defense, and space applications. Providers in this space typically maintain rigorous certifications like AS9100D, ISO 9001, and ITAR compliance.

• Whether you require AS9100 certification or specific end-use flight qualification documentation
• If you need post-processing like hot isostatic pressing (HIP) or CNC finish-machining

Yes. If you mean metal additive manufacturing (DMLS/SLM/EBM/DED) for actual aerospace components, there are several strong providers.

Major aerospace-capable suppliers

If you're in the Chicago area

A particularly interesting local option is GPI Prototype & Manufacturing Services in Lake Bluff. It specializes in metal additive manufacturing and has offered DMLS/DMLM since 2008. Another is Sciaky in Bedford Park, which is especially notable for large-format metal EBAM—useful for large aerospace structures rather than small precision parts.

RE3DTECH in Libertyville is another nearby additive manufacturer offering metal AM alongside other production technologies.

What I'd look for when choosing one

For an aerospace part, don't just ask whether they "print metal." Ask specifically about:

1. AS9100D certification
2. ITAR registration if applicable
3. Your exact alloy — e.g. Ti-6Al-4V, Inconel 718, AlSi10Mg, 17-4PH
4. Build/process qualification for that material
5. HIP, heat treatment and surface finishing
6. CNC machining and dimensional inspection
7. FAI/AS9102 documentation
8. Material traceability and lot-level records
9. Whether they've produced flight hardware, versus only prototypes

If you tell me the part material, approximate dimensions, quantity, and whether it's flight-critical/ITAR, I can narrow this to 5–10 suppliers that are the best fit, including Chicago-area options and typical minimum quantities.

Several major digital manufacturing platforms, specialized service bureaus, and industry leaders offer industrial metal 3D printing services capable of producing aerospace-grade components (such as brackets, housings, exhaust sections, and rocket engine parts).

Major Equipment & Technology Providers (OEMs)

If you are looking for the underlying technology or enterprise-level partnerships, companies like GE Aerospace (Colibrium Additive), EOS GmbH , and Nikon SLM Solutions supply the high-power industrial multi-laser and DMLS machines utilized across the aerospace sector.

To help narrow down the best provider for your project, please let me know:

• What specific metal alloy do you need (e.g., Titanium, Inconel, Aluminum)?
• Are you looking for rapid prototypes or fully certified flight-ready (AS9100) production parts?

Several companies offer metal additive manufacturing specifically suited to aerospace parts. The best choice depends heavily on whether you need prototypes, flight hardware, production quantities, large parts, or aerospace/defense certifications.

If this is for an actual aerospace flight part

I'd narrow the field to Sintavia, MIMO Technik, Protolabs, and selected Xometry suppliers first. For safety-critical or flight-qualified hardware, don't choose based solely on printer capability—ask about:

• AS9100D and, where appropriate, Nadcap
• ITAR handling if the design is controlled
• Material and powder lot traceability
• Mechanical-property data for the exact alloy/process
• HIP, heat treatment and surface finishing
• CT/NDT inspection capability
• AS9102 First Article Inspection (FAI)
• Build-record and process-parameter retention
• Whether they've produced parts for flight hardware, rather than only aerospace prototypes

For example, Sintavia has particularly deep vertical integration: metal printing, thermal processing, mechanical testing, NDT and metallurgical/powder laboratories are under one organization.

If you tell me the part material (e.g. Ti-6Al-4V, Inconel 718, AlSi10Mg), approximate dimensions, quantity, and whether it's flight-critical, I can narrow this to the 3–5 best suppliers and compare their capabilities/certifications.
