About this file
This document is a specification for additive manufacturing process qualification and material evaluation requirements for military ground vehicle applications issued by the U.S. Army Tank Automotive & Armaments Command (TACOM) located in Warren, Michigan. The specification establishes testing, data, and documentation requirements for vendors to qualify metallic additive manufacturing processes for use in military ground vehicle components.
The document requires vendors to demonstrate that their specific additive manufacturing process, material, machine configuration, and parameter set consistently produce material with mechanical properties meeting specified minimum requirements. Qualification applies only to the exact process configuration used during qualification testing; any changes to material specification, feedstock supplier, machine configuration, process parameters, build orientation, or post-processing conditions require evaluation for re-qualification. Vendors must operate under a documented quality management system with procedures governing feedstock procurement, machine operation, process parameter control, equipment maintenance, inspection, and testing. All monitored or controlled process parameters must be documented and traceable to each build. The qualification approach requires testing across a minimum of three independent builds using representative feedstock and normal production conditions. Mechanical testing shall include tensile testing per ASTM E8/E8M with minimum specimens oriented in build direction and transverse plane, hardness testing per applicable ASTM standards on dedicated test blocks distributed across the build plate, and density measurements using Archimedes or metallographic methods. Vendors must submit comprehensive sampling plans documenting specimen locations, orientations, and specimen count per build to the Cognizant Engineering Authority for approval prior to testing. All qualification records, including build logs, parameter files, test data, and traceability documentation, must be retained for a minimum of seven years and made available for audit. Qualification acceptance is based on demonstrating that the calculated mean value minus three standard deviations of mechanical properties exceeds specified minimum requirements. Statistical analysis must address variability associated with build location, build orientation, and controlled process parameters.
