Industrial additive manufacturing has moved beyond prototyping, with manufacturers using it for functional parts, tooling and complex components across industries such as aerospace, automotive and energy.
As production scales, quality, consistency and traceability become just as important as the part itself. Standards such as ISO 9001 and AS9100 provide structured frameworks to control processes, meet requirements and support continuous improvement.
For manufacturers adopting industrial additive manufacturing, understanding these standards can help build reliable processes and prepare for larger-scale production.
Why Standards Matter in Industrial Additive Manufacturing
Additive manufacturing has variables that influence the final part such as material condition, machine settings, build orientation, post-processing and inspection.
If processes are not controlled properly, inconsistent results are difficult to trace. A quality management system can assist by defining procedures, responsibilities and records to make production more consistent and reliable.
That is why standards are key when moving from experimental production to reliable additive manufacturing solutions.
What Is ISO 9001?
ISO 9001 is one of the most recognised standards for quality management in the world. It provides the framework for establishing and maintaining a quality management system based on consistent processes, customer requirements and continual improvement.
ISO 9001 does not mean every printed part that comes out of an additive manufacturing company is automatically defect-free. Instead it shows that the organisation has a systematic way of managing quality.
This can cover areas such as:
- Document and record control
- Customer requirements
- Supplier management
- Employee competence and training
- Production and process controls
- Non-conformance management
- Corrective actions
- Risk-based thinking
- Internal audits
- Continual improvement
These areas can be particularly useful in additive production, where traceability and process consistency can become increasingly important as production volumes grow.
How ISO 9001 Applies to Additive Manufacturing
Consider a manufacturer producing polymer or metal components for industrial customers. Before production, it may define material specifications, machine settings, inspection requirements and acceptance criteria. Production records also help track parameters and address issues when a part fails inspection.
ISO 9001 provides a structured framework for managing these activities. It also connects design, material procurement, printing, post-processing and inspection into one controlled process, which is especially valuable for delivering reliable additive manufacturing solutions.
What Is AS9100?
For companies working in aerospace and related sectors, AS9100 is an important standard to understand.
AS9100 builds on the principles of ISO 9001 but includes additional requirements designed for the aerospace, space and defence industries. These sectors typically demand strong levels of traceability, risk management, configuration control and product assurance because component failure can have serious consequences.
For manufacturers using additive technologies in aerospace applications, AS9100 can therefore provide a more industry-specific quality framework.
Its requirements address areas such as:
- Operational risk management
- Product safety
- Configuration management
- Counterfeit-part prevention
- Supplier controls
- Traceability
- Production planning
- Inspection and verification
- Non-conforming outputs
- Change management
The exact requirements applicable to an organisation depend on its activities, customers and certification scope.

What Manufacturing Standards Mean for Additive Production
Manufacturing standards cover more than ISO 9001 and AS9100. In additive manufacturing, they can address materials, equipment, testing, inspection, design and production processes.
Compliance is not just about certification. Customers may also expect evidence of material traceability, controlled production parameters, equipment maintenance and proper inspection. Standards should therefore be part of a broader quality strategy.
Building a Standards-Ready Additive Manufacturing Process
Getting ready for certification or customer audits does not necessarily begin with paperwork. It starts with understanding the production process from end to end.
A manufacturer can begin by mapping the complete workflow:
Design → Material → Machine Preparation → Build → Post-Processing → Inspection → Documentation
Each stage should have clear responsibilities and defined controls.
Material management can include supplier approval, batch tracking and proper storage, while production requires documented machine settings and build records. Post-processing and inspection should also follow controlled procedures.
Together, these records provide traceability, allowing manufacturers to verify how a component was produced even after delivery.
Certification Is Not the Same as Compliance
One common misconception is that obtaining ISO 9001 or AS9100 certification means every product automatically complies with every applicable technical requirement.
That is not how certification works.
A quality management certification generally demonstrates that an organisation's management system has been assessed against the relevant standard. It does not automatically approve individual designs, materials or production processes.
A particular additive manufacturing project may still require additional qualification, testing, validation or customer approval.
Understanding this distinction prevents manufacturers from treating certification as a shortcut. The real value comes from using the quality system to make production more controlled and predictable.
How Standards Support Growth
As an additive manufacturing business grows, standards become increasingly important. Documented processes reduce dependency on individual experience, make it easier to investigate problems, and help maintain consistency across machines and teams. For customers, they also offer confidence that quality is being managed in a systematic way, particularly when industrial additive manufacturing moves from prototyping to repeat production.
Preparing for the Future of Industrial Additive Manufacturing
With the maturation of additive technologies, requirements for consistency, traceability, and quality assurance will likely become more important.
Manufacturers that develop strong quality systems early on may find themselves in a better position to enter regulated or demanding markets. Standards can be seen by businesses as part of the infrastructure needed to scale, not as a barrier.
The goal is not only to collect certifications. The goal is to have a production environment where processes are understood, risks are controlled, changes are controlled, and results can be demonstrated with credible evidence.
For companies developing advanced additive manufacturing solutions, the foundation can be just as important as the printer, material, or software used to make the part.
Conclusion
The industrial additive manufacturing sector is attaching growing importance to certification and standards. ISO 9001 provides a broad quality management framework, AS9100 extends those principles for the specific needs of aerospace, space and defense. For companies such as Rapid Fusion, these standards support the development of reliable, repeatable additive manufacturing processes for demanding industrial applications.
However, certification alone does not ensure a successful additive manufacturing process. Its value is in establishing disciplined systems of materials, production, inspection, documentation, risk management and continual improvement.
For manufacturers who want to make additive technology a reliable production capability, knowledge of these manufacturing standards is an important step.
Frequently Asked Questions
Is ISO 9001 required for industrial additive manufacturing?
ISO 9001 is not universally required for additive manufacturing. However, customers or contracts may require suppliers to operate under a certified quality management system. The relevance of ISO 9001 depends on the industry, application and customer requirements.
Is AS9100 better than ISO 9001 for aerospace additive manufacturing?
AS9100 is specifically designed for aerospace, space and defence applications and includes requirements beyond the ISO 9001 framework. For suppliers serving these sectors, AS9100 may be more appropriate where customers or contracts require aerospace-specific quality management.
Does ISO 9001 certify an additive manufacturing part?
No. ISO 9001 certification applies to an organisation's quality management system rather than automatically certifying individual parts. Specific components may still require testing, inspection, validation or other technical approvals.
Why is traceability important in additive manufacturing?
Traceability helps manufacturers connect a finished component with relevant information such as material batches, production records, machine parameters, inspection results, and post-processing activities. This can support quality investigations and customer requirements.
Can standards help an additive manufacturing company scale production?
Yes. Standards can encourage consistent procedures, clearer documentation, controlled processes and systematic improvement. These practices can become increasingly valuable as production volumes increase, more employees become involved and customers demand stronger quality assurance.
