Additive manufacturing of metals — Test artefacts — Compression validation specimens for lattice designs
This document defines testing coupons and methods for the evaluation of the compression strength of AM lattice designs. The standardized test coupons will accommodate the application of a variety of lattice designs, while standardizing the evaluation method. This document is generally intended to be used in validation or verification activities for an additively manufactured component that incorporates a lattice or porous (non-solid) design. Details may include limits or requirements for minimum repeated elements and relative dimensions of the specimen. Note: Due to inherent variability across the manufacturing of AM components, evaluation methods are needed. Specifically, when an eventual component is intended to be subjected to compressive loads, a representative testing coupon is needed to represent the component to undergo destructive evaluation as a surrogate for the component itself.

Overview
ISO/ASTM FDIS 52959:2025 is an international standard developed jointly by ISO Technical Committee 261 and ASTM Committee F42. It specifies test artefacts and procedures for evaluating the compression strength of metallic additive manufacturing (AM) lattice designs. This standard addresses the need for representative, standardized compression specimens to validate and verify AM components that incorporate complex, porous lattice structures. It ensures consistent quality assurance in compression testing by defining specimen geometry, manufacturing constraints, and testing methods tailored specifically for lattice architectures in metal additive manufacturing.
By standardizing test coupons and evaluation methods, ISO/ASTM FDIS 52959 facilitates reliable destructive testing on samples that accurately represent the mechanical behavior of AM lattice components under compressive loads. The standard is designed to accommodate a wide variety of lattice designs and materials, offering clear guidelines on specimen design, testing protocols, and reporting requirements.
Key Topics
- Scope and Application: Defines testing coupons for axial compression evaluation of AM metallic lattices and guidance on specimen preparation for validation of compressive strength.
- Specimen Design: Details requirements for specimen shapes (rectangular cuboid or cylindrical), minimum unit cell counts or mean void intercept length (MVIL) criteria to ensure representative lattice volume, and options for incorporating endplates to improve load distribution.
- Testing Procedure: Specifies cleaning, visual inspection, dimensional measurement, and identification protocols essential for reliable compression testing of AM lattice specimens. Emphasizes aligning build orientation with expected compressive load and controlling manufacturing variables.
- Loading and Measurement: Provides methodologies to estimate compressive lattice stress using either endplate area or projected lattice cross-section, including dynamic test data collection and deformation monitoring.
- Material Considerations: Addresses differences in testing requirements for ductile versus brittle materials, with distinct minimum unit cell configurations for each.
- Safety and Hazards: Advises on handling metallic powders and potential specimen fracture hazards during compression, recommending compliance with ISO/ASTM 52931 and use of personal protective equipment (PPE).
- Traceability and Reporting: Mandates comprehensive specimen identification including material, lattice configuration, specimen dimensions, build parameters, and any deviations from the standard to facilitate reproducibility and auditability.
Applications
ISO/ASTM FDIS 52959 is essential for industries employing additively manufactured metal parts with lattice or porous designs where compressive load performance is critical. Typical applications include:
- Aerospace and Automotive: Validation of lattice structures integrated into lightweight, load-bearing components to optimize weight-to-strength ratios.
- Medical Implants: Compression testing of porous metallic implants designed for bone ingrowth and load transfer.

Introduction
Validation and verification activities to support the manufacture of components are critical quality
requirements to ensure reliable production of consistent parts. Additive manufacturing (AM) offers the
opportunity to seamlessly incorporate computationally designed, high resolution, lattice structures into
components. On the other hand, AM systems can have different capabilities in terms of feature resolution,
therefore impacting physical properties of lattice structures. In order to ensure quality requirements, there
is a need to develop standardized lattice specimen geometries that can be used as surrogates in destructive
evaluations. Specifically, components incorporating lattice structures can be placed under compressive
loads. Since lattice designs, including, beam, gyroid or schwartz, can be unique to manufacturers, a
standardized approach is needed to ensure that the lattice design is adequately represented and can be
consistently assessed. This can allow for the evaluation of the compressive mechanical strength with
adequate representation of the manufacturing of the lattice design.
This document provides the lattice compression specimen and other AM specific considerations for using
the specimen per an existing compression test method like ASTM E9 or ISO 13314. Although ASTM E9 and
ISO 13314 provide standard methods of compression testing for metallic materials, in this document specific

Introduction
Les activités de validation et de vérification à l’appui de la fabrication des composants sont des exigences
essentielles pour garantir la production de manière fiable des pièces cohérentes. La fabrication additive
(FA) offre la possibilité d'incorporer de manière transparente dans les composants des structures en treillis
à haute résolution conçues par ordinateur. D'autre part, les systèmes de FA peuvent avoir des capacités
différentes en termes de résolution des caractéristiques, ce qui a un impact sur les propriétés physiques des
structures en treillis. Afin de garantir les exigences de qualité, il est nécessaire de développer des géométries
normalisées d'éprouvettes de treillis qui peuvent être utilisées comme substituts dans les évaluations
destructives. Plus précisément, les composants incorporant des structures en treillis peuvent être soumis
à des charges de compression. Étant donné que les conceptions de treillis, de faisceau, de gyroïde ou de
schwartz peuvent être uniques aux fabricants, une approche normalisée est nécessaire pour garantir que la
conception de treillis est représentée de manière adéquate et peut être évaluée de manière cohérente. Cela
peut permettre d’évaluer la résistance mécanique à la compression avec une représentation adéquate de la
fabrication de la conception de treillis.
Le présent document fournit l'éprouvette de compression en treillis et d'autres considérations spécifiques
à la FA pour l'utilisation de l'éprouvette selon une méthode d'essai de compression existante telle que
l’ASTM E9 ou l’ISO 13314. Bien que l’ASTM E9 et l’ISO 13314 fournissent des méthodes normalisées d'essai
de compression pour les matériaux métalliques, le présent document tient compte de considérations
spécifiques aux structures en treillis, telles que le nombre minimum de cellules unitaires, les considérations
relatives aux matériaux ductiles et fragiles, la possibilité de construire des éprouvettes avec des plaques
d'extrémité et les différences entre les treillis réguliers et non réguliers, ainsi que des exigences en matière
de rapports sur les paramètres de fabrication de FA.
