AM certifications guide: what's required, by industry

Additive manufacturing sits at the intersection of materials science, process engineering, and quality systems — and regulators have taken notice. Whether you are qualifying a titanium bracket for aerospace, a polymer implant for medical use, or just bidding on a defense contract, certification requirements will shape your process.

This guide maps the certification landscape by industry, explains what each standard actually covers (not just what it's called), and gives you a realistic picture of effort and cost.

The two types of certification

Before going through each standard, it's worth understanding the distinction:

Process certification — certifies that your facility and process can produce parts to a defined quality level. Examples: AS9100D, NADCAP, ISO 9001. You hold the certificate; it applies to your site.

Product/material qualification — certifies that a specific material or part geometry meets defined mechanical and microstructural requirements. Examples: AMS 7003 (Ti-6Al-4V LPBF), ASTM F3001. The OEM or prime contractor usually drives this; you provide test data.

Most serious AM shops need both: a process certificate for their quality management system, and material/product data to satisfy each customer's design approval.

Universal baseline — ISO 9001 & ISO/ASTM 52900 series

ISO 9001:2015 — Quality Management System

What it is: The baseline quality management system standard. Required as a prerequisite by almost every sector-specific standard (AS9100D, ISO 13485, IATF 16949).

What it covers: Document control, design control, nonconforming product, corrective action, management review, internal auditing.

AM relevance: Does not address AM-specific requirements (traceability of powder lot, build parameter control, post-process thermal treatment). Most AM shops treat ISO 9001 as the floor, not the ceiling.

Cost/effort: £15,000–£50,000 for a small shop to implement + annual surveillance audit.

ISO/ASTM 52900 — General Principles and Terminology

Not a quality management standard — it's the AM vocabulary standard. Defines the seven process categories (binder jetting, directed energy deposition, material extrusion, material jetting, powder bed fusion, sheet lamination, vat photopolymerization). Referenced by all other AM standards.

ISO/ASTM 52904 — Practice for Metal Powder Bed Fusion

What it covers: Specifies minimum requirements for the AM process (machine qualification, powder lot control, parameter set control, witness specimens, post-processing documentation). The closest thing to an AM-specific process standard for LPBF.

Who requires it: Increasingly referenced in aerospace and defense procurement specifications. Doesn't replace AS9100D but is often required in addition to it.

Aerospace — AS9100D + NADCAP

AS9100D — Aerospace Quality Management System

Publisher: SAE International / IAQG (International Aerospace Quality Group)

What it is: AS9100D = ISO 9001 + aerospace-specific additions (configuration management, first article inspection, key characteristics, traceability to raw material).

What AM operations need to add beyond ISO 9001:

• Powder lot traceability (cert from atomizer → receipt inspection → build → part)
• Build parameter version control (a "recipe change" is a design change)
• Witness specimens in every build (dog-bones or tensile bars printed alongside production parts)
• Machine qualification and requalification schedule
• Post-process chain documentation (HIP, heat treat, machining, NDT, inspection)

Who holds it: Your facility does. AS9100D is site-specific — a second facility requires a separate certificate.

Cost: Typically 12–18 months of implementation + £20,000–£80,000 in consulting and audit fees for a first-time applicant.

Key CBs: Bureau Veritas, TÜV Rheinland, DNV, SGS, NQA.

NADCAP — National Aerospace and Defense Contractors Accreditation Program

Publisher: PRI (Performance Review Institute)

What it is: Supplemental accreditation for special processes — processes where a defect is not detectable after the fact (welding, heat treat, NDT, chemical processing). NADCAP is increasingly requiring an AM accreditation category.

NADCAP AC7110/14 — Additive Manufacturing of Metals (draft/active)

The NADCAP AM checklist covers:

• Machine performance verification (laser power calibration, beam quality, atmospheric O₂/N₂ levels)
• Powder handling and storage (moisture, contamination, recycling limits)
• Build parameter set control and change management
• Post-process heat treatment (covered under separate NADCAP AC7102 Heat Treat)
• Non-destructive testing (CT scan, X-ray, HIP qualification)

Who requires NADCAP: Boeing, Airbus, GE Aviation, Raytheon, Safran, Rolls-Royce — essentially every Tier 1. Many Tier 2 contracts also mandate it.

Medical — ISO 13485 + FDA/CE pathways

ISO 13485:2016 — Medical Device Quality Management System

What it is: The medical sector equivalent of AS9100D. Adds risk management (ISO 14971), design validation, post-market surveillance, and unique device identification requirements.

AM-specific challenges:

• Process validation (3× equipment installation qualification / operational qualification / performance qualification = IQ/OQ/PQ)
• Biocompatibility testing of the printed material (ISO 10993), not just the feedstock
• Cleaning and sterilisation validation for implantable parts
• Change control — a nozzle replacement on your FDM machine can require revalidation

CE Marking (Europe): Requires a Notified Body audit under EU MDR 2017/745. Class IIa and above implants require full technical file submission. AM-specific guidance was published in 2021 by EUDAMED.

FDA (United States): The FDA published "Technical Considerations for Additive Manufactured Medical Devices" (2017, updated guidance 2024). For Class II devices: 510(k) substantial equivalence pathway. For Class III (implants, life-sustaining): PMA (Pre-Market Approval).

FDA AM-Specific Considerations

The FDA guidance explicitly calls out:

• Device design — software version control, file format (.STL, .AMF, .3MF) traceability
• Software workflow — validation of slicer and build preparation software as medical device software (IEC 62304)
• Post-processing — each step (support removal, surface finishing, sterilisation) must be validated separately
• Dimensional verification — sampling plan must account for build position and orientation variability

Defence (TR/NATO/DOD)

Turkish Defence — SSB Qualification

Turkey's Defence Industries Presidency (SSB) requires:

• AS9100D or equivalent Turkish equivalent (TSE ISO 9001 is accepted as a baseline)
• AFNOR/NATO STANAG 4671 for unmanned systems
• For AM-produced defence parts: material qualification per AMS or equivalent + AS9100D at the production facility

TEI (TUSAŞ Engine Industries) and Aselsan are the primary primes and have internal supplier qualification programmes that mirror NADCAP requirements without the formal NADCAP certificate.

US DoD — MIL-HDBK-1823A (NDE) + AM Roadmap

The US DoD published an AM Roadmap that mandates:

• Traceability to powder atomisation lot
• In-situ process monitoring (melt pool imaging or pyrometry) for structural parts
• CT scanning for complex internal geometry
• Mechanical test data (tensile, fatigue, fracture) with process parameters documented

Material qualification standards (not facility certs)

Note: AMS 7003 and ASTM F3001 are material standards — they specify chemistry, microstructure, and minimum mechanical properties. They do not certify your shop. The OEM specifies them on the drawing; you must demonstrate compliance with test data.
