Precision and accuracy have become the two unnegotiable factors in manufacturing today. From aerospace & defence to automotive, medical devices to die & mould industries, the demand for flawless
components has pushed the boundaries of measurement technology. At the forefront of this evolution is 3D metrology, which is redefining how manufacturers inspect, analyse, and ensure the quality of their products with unmatched accuracy and efficiency.

What is 3D Metrology?
3D metrology is the science of measuring objects in three dimensions to capture their precise geometric
data. It verifies components’ dimensions, shape, and surface characteristics using state-of-the-art tools and techniques.
Some 3D Measurement Tools
– Coordinate Measuring Machine (CMM) measures the geometries of physical objects.
– 3D Automated Optical Inspection (AOI) systems use advanced imaging techniques to track defects in products.
– Optical Digitizer and Scanner (ODS) uses laser or white light-based scanning technology to capture an object’s geometry by collecting multiple coordinate points, which are then reconstructed into a digital model using specialised software.
– Video Measuring Machine (VMM) is an advanced instrument used for accurate dimensional analysis.
How Does It Work?
The 3D metrology process can be summarised into four key steps:
– Data Collection: In this stage, detailed measurements of a component’s shape, contours, and features are collected.
– Data Processing and Analysis: The collected raw data is then fed into a data processing software to create an accurate 3D model.
– Comparative Analysis: In this stage, the created 3D model is compared with a reference CAD model to check for deviations.
– Visualisation and Reporting: The data acquired from the comparative analysis is then used to generate a comprehensive report summarising the findings.
