K3 Metrology Intros Advanced Real-Time Metrology Platforms

K3 Metrology, a UK-based spin-out from the National Physical Laboratory (NPL), has introduced Metralis, a next-generation real-time coordinate measurement platform developed for advanced manufacturing environments requiring high-accuracy metrology, process-integrated inspection, and scalable automated measurement capabilities.

The company recently launched with £2.75 million in seed funding to support commercialization of the technology across aerospace, defense, nuclear, and other high-value industrial sectors. The funding round included investment from the Development Bank of Wales, Parkwalk, and the UK Innovation & Science Seed Fund (UKI2S).

Developed through more than 12 years of collaborative research at NPL, the Metralis platform was designed to address limitations associated with conventional large-volume coordinate measurement systems used in automated manufacturing, machining, and assembly environments. The technology is intended for applications including metrology-assisted machining, automated assembly verification, precision alignment, and real-time manufacturing process validation.

According to K3 Metrology, the system operates conceptually in a manner similar to GPS-based global navigation systems, using multiple distributed sensors positioned around a working volume to simultaneously detect and measure multiple points of interest. The platform uses frequency scanning interferometry to perform high-accuracy distance measurements with repeatability of approximately 1 μm and accuracy of 2 ppm over distances up to 10 meters.

The company stated that the platform is self-calibrating, enabling sensor positions and related system parameters to be derived directly from measurement data at the time of use. The technology also incorporates direct traceability to the International System of Units (SI) using a quantum frequency reference based on a gas absorption cell, reducing the need for traditional physical scale bars and routine factory recalibration procedures.

K3 Metrology noted that the system’s self-calibration mathematics additionally provide built-in uncertainty estimation capabilities designed to account for environmental and instrument-related variables that may influence measurement performance within industrial environments.

The technology was developed in response to feedback from manufacturers seeking more scalable, flexible, and process-integrated metrology systems capable of supporting advanced manufacturing workflows. During customer trials, the company reported substantial performance improvements compared with conventional measurement approaches. A timing study conducted with a manufacturing partner found that use of the Metralis platform resulted in efficiency gains of approximately 60%.

“For decades, manufacturers have been forced to compromise between accuracy, speed and scalability. Metralis removes that trade-off entirely,” said Dr Mike Campbell, CEO of K3 Metrology. “This investment enables us to bring a step-change technology to market and support the UK’s most advanced industrial sectors. Metralis is the result of years of scientific development at NPL, and we are now grateful for the support of the Development Bank, Parkwalk and UKI2S. Our team is excited to deliver real-time, high-accuracy measurement at a scale that has never before been possible.”

NPL stated that the technology has the potential to improve industrial productivity, strengthen manufacturing competitiveness, and support next-generation manufacturing applications requiring scalable precision measurement and traceable metrology capabilities.

“K3 Metrology Ltd demonstrates how publicly funded science can translate into high value industrial capability for the UK,” said Penny Holt, Chief Financial Officer of NPL. “Metralis is a transformative technology with the ability to raise industrial productivity, strengthen UK manufacturing competitiveness, and set new international standards in large volume measurement.”

K3 Metrology is based at the Advanced Manufacturing Research Centre Cymru (AMRC-C) in Broughton, Wales, where the company continues development and industrial deployment activities focused on advanced manufacturing and precision engineering applications.
