Our Commitment to Quality

AS9100 D:2016  |  ISO 9001:2015  Certified | ITAR Registered

At Midwest Prototyping, quality has been our driving force since day one and continues to be the centerpiece of our operations. To us, that quality is more than simply building parts to the specified dimensions. It means a quality experience for our clients, every step of the way. Our customers are the basis for our quality policy:

“We continually improve to surpass our customers’ requirements and provide better parts faster.”

As we shift from prototyping to production, we recognize the importance of a responsive quality management system. Additive manufacturing presents an uncharted set of challenges. Above all, we’ve sought to maintain standards of operational excellence and continual improvement in every aspect of our organization. That’s why we’ve taken the steps necessary to become the first independent additive manufacturing service bureau to become ISO 9001:2015 certified and have followed that with our AS9100 D:2016 certification for aerospace manufacturing.
