ISO/IEC 16466:2025

This document specifies methods and metrics for assessing the accuracy and precision of 3D scanned data for use in 3D printing, throughout the full 3D printing lifecycle.

This document focuses mainly on 3D scanned data from computed tomography. Computed tomography can acquire information concerning the internal structures, regional density, orientation and/or alignment of scanning objects, as well as their shape and appearance.

This document is applicable to the assessment of image-based modelling, segmentation, and 3D models.

This document is not intended to assess the 3D printed product itself.
