If you can share:

• The specific metal alloy you need (e.g., Titanium Ti6Al4V, Inconel, Aluminum)
• Whether you require end-use flight hardware or prototypes
• Estimated part size or volume

I can help narrow down which provider matches your exact technical requirements.

Yes. If you mean industrial metal additive manufacturing for aerospace parts, with an aerospace quality system such as AS9100/EN9100, there are several strong U.S. and international suppliers.

Strong candidates

• Sintavia — A particularly strong fit for flight-critical metal AM. Sintavia is AS9100 Rev. D certified, Nadcap accredited, ISO/IEC 17025 accredited, and ITAR registered. Its Nadcap scope includes laser/e-beam additive manufacturing, heat treatment, NDT, and materials testing.
• Stratasys Direct — Provides aerospace production 3D printing, including metal capabilities, with AS9100 and ISO 9001, ITAR registration, and AS9102 First Article Inspection capability. It reports more than 115,000 qualified parts shipped annually.
• 3D Systems — Offers aerospace/defense metal additive manufacturing and operates AS/EN9100-certified production facilities. It also supports aerospace certification and process qualification.
• Materialise — Especially interesting if you need flight-ready aerospace parts rather than merely prototype printing. Its aerospace operation is EASA Part 21.G certified, manufactures metal parts under EN9100, and works to Airbus AIPI standards.
• American Additive Manufacturing — U.S.-based supplier with AS9100D, ISO 9001, and ITAR registration. Its metal capability includes EOS DMLS and SLM equipment, with aluminum, titanium, and Inconel production.
• i3D MFG — Now part of BTX Precision. It operates 30 EOS DMLS machines and reports AS9100D, CMMC compliance, and ITAR registration, making it worth considering for higher-volume aerospace/defense metal production.
• Protolabs — Offers aerospace 3D printing with AS9100D and ITAR compliance. It is attractive for rapid quoting and prototypes/production, although for a highly flight-critical metal component I'd verify the exact material/process qualification required for your part.

If this is for an actual aerospace part

I'd narrow the supplier based on what certification you actually need, because "AS9100 certified" does not by itself mean that a particular printed part or AM process is approved for installation on an aircraft.

For example, if you need flight-critical metal components, I'd put Sintavia near the top of the list because its qualifications extend beyond AS9100 to Nadcap AM, heat treatment, NDT, materials testing, and ISO/IEC 17025 laboratory accreditation.

If you tell me the metal (Ti-6Al-4V, Inconel 718, AlSi10Mg, stainless, etc.), approximate part size, quantity, and whether it's commercial aerospace, defense, or space, I can narrow this to 3–5 suppliers that can actually manufacture that type of part and compare their certifications, machines, location, and likely suitability.

Yes. If by “aerospace certification” you mean a supplier that can produce metal AM parts under an AS9100 quality system, with traceability and potentially Nadcap/ITAR/FAI support, there are several strong options:

• Sintavia — One of the strongest fits for flight-critical metal additive manufacturing. It is AS9100/9110 certified, Nadcap accredited, ISO/IEC 17025 accredited, and ITAR registered. Its Nadcap scope includes laser/e-beam AM, heat treatment, NDT and materials testing.
• Stratasys Direct — Offers industrial metal 3D printing including DMLS, with AS9100 and ISO 9001, ITAR registration and in-house AS9102 First Article Inspection capability.
• 3D Systems — Provides aerospace metal additive manufacturing and has AS/EN9100 production facilities in the U.S. and Europe, plus engineering and certification support.
• Protolabs — Offers DMLS metal printing in aerospace applications, with AS9100D, ISO 9001 and ITAR credentials, plus HIP and CNC post-processing and AS9102-compliant FAI documentation.
• American Additive Manufacturing — U.S. contract manufacturer offering DMLS in aluminum, titanium and Inconel, with AS9100D, ISO 9001 and ITAR credentials.
• voestalpine High Performance Metals — Provides aerospace additive manufacturing with AS9100 + ISO 9001 certification and supports both prototyping and serial production.
• Wipro 3D — Provides certified metal AM for aerospace/defense, including serial production, with EN/AS9100 compliance and Nadcap capabilities.

My shortlist

For actual flight hardware rather than prototypes, I'd start with:

1. Sintavia — particularly compelling if you need Nadcap and extensive material/process qualification.
2. Stratasys Direct — good general-purpose aerospace production supplier with broad AM capabilities and FAI.
3. 3D Systems — strong if you need engineering + certification + production under one organization.
4. American Additive — attractive U.S. option, particularly for DMLS titanium/Inconel/aluminum.

One important distinction: AS9100 certification of the manufacturer does not automatically mean your particular printed part is “aerospace certified” or approved for flight. For a flight-critical component, you'll want to specify the required material/process specification, machine/process qualification, heat treatment/HIP, NDT, dimensional inspection, powder/batch traceability, witness coupons, AS9102 FAI, and customer/OEM approval in the RFQ.

If you tell me the metal (e.g. Ti-6Al-4V, Inconel 718, AlSi10Mg), approximate part size, quantity, and whether it's flight-critical, I can narrow this to the 5–10 best suppliers and compare their certifications, technologies, U.S. locations, and likely suitability.

Several prominent industrial 3D printing service bureaus and contract manufacturers specialize in metal additive manufacturing (such as DMLS / Laser Powder Bed Fusion) and hold critical AS9100 or equivalent aerospace quality certifications.

If you'd like, I can:

• Provide details on specific metal alloys (like Inconel or Titanium) available through these providers
• Break down the differences between AS9100D and ISO 9001 requirements for flight-ready parts

Several prominent industrial 3D printing service providers and digital manufacturing bureaus specialize in metal additive manufacturing backed by rigorous aerospace quality certifications (such as AS9100, ITAR compliance, and ISO standards).

Key industry providers offering certified metal 3D printing services include:

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

• What specific metal alloy (e.g., Inconel, Titanium, Stainless Steel) do you need?
• Are you looking for flight-ready end-use production parts or initial prototypes?

Yes. If by “aerospace certification” you mean a supplier with an aerospace-quality system such as AS9100/AS9100D, plus metal additive manufacturing and the ability to provide production-quality documentation, there are several strong options.

Strong U.S. options

• Stratasys Direct — Offers industrial metal additive manufacturing and aerospace production services. It is AS9100 and ISO 9001 certified, ITAR registered, supports material/process specifications, traceability, inspection, and AS9102 First Article Inspection.
• 3D Systems — Has aerospace/defense additive-manufacturing operations with AS/EN9100-certified production facilities, including its Littleton, Colorado facility. Its capabilities include metal additive manufacturing and production process development.

If certification level is the key criterion

I'd put Sintavia near the top for highly regulated aerospace/propulsion applications because Nadcap + AS9100 + ISO/IEC 17025 goes considerably beyond simply having an AS9100-certified quality-management system.

For a more general production metal-part supplier, I'd shortlist Stratasys Direct, Protolabs, i3D MFG, and American Additive.

One important distinction: AS9100 certification does not automatically mean that every printed part is “flight certified.” The actual part may require an approved material/process specification, machine/process qualification, traceability, heat treatment, HIP, NDT, mechanical testing, FAIR/FAI, and/or customer/OEM approval.

If you tell me the metal (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 their certifications, processes, materials, location, and likely suitability.

Yes. If by “aerospace certification” you mean a supplier with an AS9100/AS9100D quality system and the ability to produce metal AM parts with aerospace-grade documentation/traceability, there are several strong options.

Strongest candidates

• sintavia.com — One of the most aerospace-focused choices. It has AS9100/9110, Nadcap, ISO/IEC 17025 and ITAR credentials, with Nadcap accreditation covering areas including laser/e-beam additive manufacturing, heat treatment, NDT and materials testing.

If you're in the Chicago area

A particularly relevant local option is Sciaky in Bedford Park. Sciaky specializes in large-format metal additive manufacturing using electron-beam technology (EBAM) and provides contract metal-AM services. Its technology is especially interesting for large titanium, nickel and other high-value aerospace components.

For aerospace certification specifically, however, I'd put Sintavia, Stratasys Direct, Protolabs, 3D Systems, and American Additive ahead of a generic local 3D-printing shop because their published quality systems and aerospace programs are much clearer.

Important distinction: AS9100 certification by itself doesn't mean that every printed part is flight-certified. For a flight-critical component, I'd ask the supplier about the exact material/process qualification, machine qualification, powder traceability, build records, heat treatment/HIP, NDT, CT/CMM inspection, mechanical testing, and AS9102 FAI required by your drawing or OEM specification.

If you tell me the metal (Ti-6Al-4V, Inconel 718, AlSi10Mg, stainless, etc.), approximate part size, and whether you're looking for prototype or flight-production quantities, I can narrow this to the 5 best suppliers and compare their certifications, technologies, location, and likely fit.

Several prominent industrial additive manufacturing (AM) service providers and manufacturers offer metal 3D printing (such as DMLS, SLM, and EBM) backed by rigorous aerospace quality management certifications like AS9100D (US) or EN9100 (Europe), along with ITAR compliance and full material traceability.

To help narrow down the best partner for your specific project, could you share:

• What metal alloy do you need (e.g., Titanium Ti6Al4V, Inconel, Aluminum)?
• Do you require end-use flight hardware or initial prototypes?
• What geographical region do you need the manufacturing facility to be located in?

If you mean industrial metal additive manufacturing (metal 3D printing) suppliers that can produce aerospace parts under aerospace-quality systems, several established providers fit that category. Common certifications to look for include AS9100D, ISO 9001, ITAR registration (for controlled U.S. defense work), AS9102 First Article Inspection (FAI) capability, material traceability, and qualified metal AM processes.

Aerospace-certified metal 3D printing service providers

For flight hardware, ask suppliers about:

• Material qualification: Ti-6Al-4V, Inconel 718, Inconel 625, AlSi10Mg, 17-4PH, etc.
• Process qualification: whether the exact alloy + machine + parameters are qualified.
• Inspection package: CMM reports, CT scanning, density testing, mechanical testing, surface finish reports.
• Traceability: powder lot/wire lot, build records, operator/machine logs.
• Post-processing: HIP, heat treatment, CNC machining, coating, shot peening.
• Aerospace documentation: AS9102 FAI, certificates of conformance, material certs.

For critical aerospace flight parts, the strongest candidates are typically the suppliers with both AS9100D certification and qualified metal AM processes, such as Stratasys Direct, American Additive, i3D MFG, Oerlikon AM, and similar aerospace-focused contract manufacturers.

If you need suppliers specifically for rocket engines, turbine components, satellite structures, defense programs, or FAA-certified aircraft parts, the shortlist changes.
