Our Path to Achieving ISO 9001:2015 Certification as a 3D Printing Service Bureau

June 10, 2025

It’s been a long time coming and involved a great deal of hard work, but we’re excited to announce that 3D Parts Unlimited has received ISO 9001:2015 quality management certification!

This is more than a certification to us, though—it’s a mark of our growth and continuous dedication to our customers. While we’d already designed our processes to provide our customers with the highest quality 3D printed parts, obtaining ISO 9001:2015 certification required us to formally document these processes and thoroughly examine each step.

Now, when you come to 3D Parts Unlimited—whether for 3D printed prototypes or volume additive manufacturing services—you can have even greater confidence in the quality of the parts you receive, and the processes used to manufacture them. 

The Value of ISO 9001:2015 Certification

3D printing service bureauISO 9001:2015 is an internationally recognized standard for quality management systems. While it’s not designed specifically for additive manufacturing, it focuses on something crucial across all industries: building strong, repeatable processes that ensure quality from start to finish.

For 3D Parts Unlimited, that means our internal systems—from how we process orders to how we maintain our 3D printers—are designed with structure, consistency, and risk mitigation in mind. It’s about making sure we’re manufacturing the highest quality parts with the correct specifications, and doing it the right way every time.

The Road to ISO 9001:2015 Certification

Obtaining ISO 9001:2015 certification involved much more than just filling out forms and checking boxes. 

Before we could apply for certification, we had to thoroughly study the ISO 9001:2015 standards and examine our existing processes to ensure they met the requirements. However, as we’d already established processes across our 3D printing service bureau with ISO 9001:2015 certification in mind, our auditor had “no findings” in our Stage I audit—a feat we were told is incredibly rare. 

However, we still needed to document our processes in detail and undergo an additional audit. This required us to create training documents, quality policies, and manuals, formalize organizational responsibilities, and develop objectives related to each of our core processes. We had to go deep into every aspect of order processing, additive manufacturing, quality control, packaging, and shipping.

But due to our dedication to quality and our meticulous engineering mindset, we passed our Stage II audit with flying colors. As a result, we received ISO 9001:2015 quality certification.

Why Choose a 3D Printing Service Bureau with ISO 9001:2015 Quality Certification?

Risk mitigation is the primary reason to choose a 3D printing service bureau that’s taken the necessary steps to achieve ISO 9001:2015 certification. The certification requires us to accurately document every process and maintain traceability for non-conforming parts to identify root causes. With standardized quality checks and recall plans, we can quickly identify the affected parts and issue a recall if a part is out of tolerance or a batch of supplier-provided material fails to meet standards.

Our ISO 9001:2015 certification confirms that 3D Parts Unlimited has the structure and processes to reliably manufacture high-quality parts and address issues effectively. And just as importantly, we have the documentation to support our processes, ensuring repeatability from prototype through production.
