Overview

EN ISO/ASTM 52902:2023 - Additive manufacturing - Test artefacts - Geometric capability assessment of additive manufacturing systems - is a CEN-adopted, international benchmark for evaluating the geometric performance of AM (3D printing) systems. Updated in 2023 and superseding the 2019 edition, this standard describes a suite of benchmark test artefact geometries and prescribes the quantitative and qualitative measurements to assess AM system capability and to support system calibration. It defines what to measure and how to report results, but does not mandate specific measurement methods or machine process settings.

Key topics and requirements

• Test artefact suite: A range of geometries (linear, circular, z-axis, resolution features, texture and labeling) designed to isolate specific geometric performance metrics.
• Measurement scope: Specifies the quantities and qualities to be measured on artefacts (dimensional accuracy, resolution features, surface texture, labelling readability), and gives examples of feature configurations for different assessment grades.
• Purpose-driven assessment: Supports two main uses - AM system capability evaluation and AM system calibration - allowing users to select artefacts relevant to their performance targets.
• Production guidance: General principles on producing artefacts: feedstock conformity, process documentation, file formats and preparation (AMF preferred with conversion guidance), orientation, part consolidation, arrays, labeling, supports and post-processing considerations.
• Measurement principles: Emphasizes measuring parts “as built,” developing a measurement strategy, and documenting measurement uncertainty and reporting requirements. Annexes provide informative guidance on measurement techniques and procedures.
• Reporting and comparability: Guidance to help compare results from one machine or across systems while accounting for uncertainty and differing measurement grades (low/high).

Applications

• Benchmarking and validating geometric accuracy of printers across technologies (metal, polymer, powder bed, material extrusion).
• Calibrating AM systems to improve dimensional fidelity and repeatability.
• Supplier qualification, acceptance testing, and process validation in production environments.
• R&D and process development to quantify limits of resolution, feature fidelity, and surface texture.

Who should use this standard

• AM system manufacturers and integrators
• Quality engineers and metrology labs
• Additive manufacturing service providers and production shops
• R&D teams developing AM processes and design-for-additive-manufacturing (DfAM) practices
