AddQual Achieves Rare Zero-Finding Nadcap 3DSL Audit

In a major quality milestone for UK-based metrology specialist AddQual in Derby, the firm has successfully completed its latest Nadcap audit for 3D Structured Light (3DSL) measurement with zero major and zero minor findings—an achievement that places it among a very small number of organisations worldwide operating at this level of compliance and precision.

The Nadcap (National Aerospace and Defense Contractors Accreditation Program) audit is regarded as the industry’s most stringent independent assessment for process control and quality assurance in sectors such as aerospace, defence, and power generation. Carried out by the Performance Review Institute (PRI), it is designed to verify that critical technical processes meet the highest standards of repeatability, traceability, and accuracy.

For AddQual, the audit result is not only a testament to its internal quality systems but also a significant endorsement of its role in supporting manufacturers who need rapid, reliable insight into complex parts and production issues. As a provider of advanced 3DSL scanning and inspection workflows, the company has built its reputation around speed and technical clarity—qualities increasingly in demand as global supply chains face mounting pressure to reduce downtime and avoid costly rework.

Managing Director Ben Anderson explains "Achieving a zero-finding Nadcap result is rare. Specific numbers of companies holding this particular 3DSL accreditation are not made public, but the limited pool of approved providers—and the high bar required to maintain such status—highlight the significance of AddQual’s result. It reinforces us as a trusted service provider and also as a benchmark for best practice in a critical area of modern manufacturing.

In traditional aerospace inspection workflows, component qualification can take days or even weeks. AddQual’s model aims to cut that down to hours, without compromising traceability or compliance. The company’s digital-first, accredited workflows are designed to support fast, confident decision-making across engineering, quality, and production teams. Whether qualifying a part for flight or resolving a production bottleneck, the firm provides metrology-backed insight that helps customers act with speed and certainty.

The Nadcap result confirms that these capabilities are not only effective, but validated at the highest level—an important distinction in sectors where trust, accuracy, and compliance are non-negotiable.
