Why ISO Certification Matters in Additive Manufacturing

Are you looking for an ISO 9001:2015 certified additive manufacturing company? 

At Re3DTech, you can be certain you’re getting 3D printing services from a team of experts committed to providing consistent, high-quality parts!

ISO certification, which establishes a standard criteria for quality management, isn’t always necessary for prototyping and functional testing. But most companies seeking 3D printing services for production orders consider ISO certification a baseline requirement. 

When one of our biggest medical industry customers told us they couldn’t qualify us as a supplier until we were ISO certified, we sprang into action. We knew—and they knew—that our parts and processes were already up to ISO standards, so the next step was getting the official certification.

The way we see it, our ISO certification shows customers that quality takes top priority and that we have the processes in place to maintain the highest level of quality for each project.

How ISO Requirements Differ for Additive Manufacturing vs. Subtractive Manufacturing

JoeISO certification was traditionally associated with subtractive manufacturing. So there has been a bit of a learning curve in defining ISO standards for additive manufacturing companies.

The documentation requirements are comparable for any type of manufacturing. But there’s variance in how parts are qualified, tested, and measured.

With machined parts, for example, there are specific tolerances to measure. But industrial 3D printing technology is capable of producing exceptionally complex geometries. It’s impossible to put a set of calipers on a 3D printed part and measure every dimension effectively. Auditors are still learning what alternative technologies to use for qualifying 3D printed parts.

The Process of Becoming ISO Certified at Re3DTech

We spent nearly two years building an infrastructure that would enable us to scale and standardize our processes. That preparation made it relatively easy for us to become ISO certified when the time came. Becoming ISO certified involved: 

  • Integrating the software we use for quoting, production, accounting, and other operations
  • Building airtight file management systems that track and show we’re always using the most current revisions for production projects 
  • Implementing training processes to ensure consistency in part production, from cleaning the printers to post-processing the parts to packaging and shipping the orders
  • Documenting the processes and operations that occur at each workstation 
  • Developing quality inspection standards for qualifying parts coming off the printer and deploying corrective action plans as needed
