Vendor Qualification Additive Manufacturing Processes

This technical document contains the engineering drawing title blocks and revision histories for US Army drawing number 12760074 (CAGE Code 19207), which outlines the "Additive Manufacturing Process Qualification and Material Evaluation Requirements." Issued by the US Army Tank Automotive & Armaments Command (CCDC Ground Vehicle System Center) in Warren, Michigan, the document spans 12 sheets under part number 12760074_A. The drawing blocks establish standard administrative, mechanical, and dimensional tolerances, specifying that all dimensions are in inches with standard tolerances for angles and decimal places. The revision history indicates an initial release on April 14, 2026, to insert a material data table (ERR TACY4104), followed by Revision A on June 14, 2026, which updated the distribution statement and revised accompanying notes (ERR TACY4179). The document is designated as Distribution Statement A, meaning it is approved for public release with unlimited distribution (OPSEC# C10669). This file serves as a standardized reference framework for qualifying additive manufacturing processes and evaluating materials for federal ground vehicle systems.

This Request for Information (RFI) is issued by the US Army Combat Capabilities Development Command Ground Vehicle Systems Center (DEVCOM GVSC) in support of Army Directive 2025-14. The purpose is to identify and qualify additive manufacturing (AM) vendors and processes to produce metal replacement parts for Army ground vehicle applications, addressing sustainment challenges where legacy components and original design data are unavailable. DEVCOM GVSC is implementing a risk-based, simplified statistical validation framework. This approach verifies that an AM process can consistently produce materials with properties meeting or exceeding original drawing specifications (e.g., μ - 3σ > S_min), rather than establishing exhaustive new design allowables. The scope covers all metal AM modalities, including laser powder bed fusion (LPBF), wire directed energy deposition (W-DED), powder directed energy deposition (P-DED), and binder jet additive manufacturing (BJAM). Prioritized materials include various steel alloys (such as PH17-4, 316L, and 42CrMo4) and high-strength aluminum alloys (Al10MgSi, AlSi7Mg06). Respondents must submit their CAGE code, Microsoft Excel-formatted quasistatic mechanical performance data, build quality evidence, and quality management documentation. All mechanical testing must be performed by a third-party certified laboratory (e.g., ISO17025 or NADCAP). Submissions and inquiries should be directed to the designated DEVCOM GVSC email address. This RFI is for information-gathering purposes only and does not guarantee future contracts.
