This is a Statement of Work (SOW) for additive manufacturing research to be conducted by the University of Texas-El Paso (UTEP) for NASA Marshall Space Flight Center (MSFC). The contract will support research related to Game Changing Development (GCD) "Additive Manufacturing for Propulsion" and Space Launch System (SLS) Liquid Engines Office (LEO) projects, building upon prior NASA awards 80NSSC22PA055 and 80NSSC23PC201.

The SOW comprises four tasks, each with 50% cost sharing between NASA and UTEP, to be completed over twelve months from contract initiation at UTEP's Keck Center. Task 1 requires evaluation of Inconel 718 L-PBF angled wall samples across 16 machine configurations to determine mechanical property variations, with deliverables including characterization, microstructure analysis, post-mechanical testing summary, and a journal article report. Task 2 involves characterization of Inconel 718 LP-DED angled wall samples to assess impacts from build parameter and geometry variations, with similar deliverables. Task 3 compares LP-DED JBK-75 powder from different vendors (PAC and HMI) with samples provided by NASA MSFC, requiring microstructure and property analysis with journal article and summary slides. Task 4 provides comparative data on Aconity beam shaping laser systems versus standard fixed focus systems using identical powder and alloy specifications, with final report and summary slides required. All deliverables include post-mechanical testing evaluation, fractography analysis, and technical reporting in journal article format where applicable.
