Objectives • Enable OEMs to productionize FDM Hardware• Raise Manufacturing Readiness Level (MRL) of
FDMTM technology for aerospace and defense applications from level 4 to level 7
• Build a platform for long-range technical and economic developments for Additive Manufacturing technology
Project Scope• Task 1: Design Allowables• Task 2: Certification Procedures• Task 3: Design Guide• Task 4: Validation• Task 5: Final Report
NAMII Project Scope
Task 1 – Design Allowables
Phase I(FDM Parameter Investigation)
Phase II (B-Basis Allowables Testing)
Process Parameter Exploration• Influence on strength DOE’s• Influence on manufacturing yield DOE’s• Influence on manufacturing rate & cost DOE’s• Sub-element scoping
Down-Select DOE Parameters
Comprehensive Materials Database• Strengths (tensile / compression / shear)• Moduli (tensile / compression / shear)• Bearing Strength• Tension Creep• Fatigue• Thermal (expansion / specific heat / diffusivity)• Poisson's Ratio• Density
Phase III (Supplementary Testing)
Supplementary Testing• Test hardware representative sub-elements• Bolt holes, connections, thick wall, thin wall, tooling etc.• Chemical resistance

DOE Sustainability Goals• Reduced lifecycle energy cost of the FDMTM process compared to parts manufactured using the alternate
conventional manufacturing process• Energy efficiency of FDMTM manufacturing as compared to parts manufactured using the alternate
conventional manufacturing process• Environmental sustainability impacts of FDMTM manufacturing
Industry Energy Savings• Reductions in material use compared to existing conventional manufacturing process.• Energy savings from material substitution, including reduction in fuel burn as a result of light-weighting
structures.• Process energy of FDMTM manufacturing a part as compared to the conventional manufacturing process.• Reduction in water use as a result of using FDMTM manufacturing as compared to the conventional
manufacturing process.• Plant energy savings due to process overhaul resulting from utilization of FDMTM manufacturing compared to
the conventional manufacturing process.
Sustainability Overview

Secondary Education• Module presented during summer camps held at the University of Dayton: focus on introducing high school students
to careers in engineering.
Community College• Design Guide data & non-proprietary processes share with Sinclair Community College, Dayton, Ohio, which operates
the National Center for Manufacturing Education (NCME) for workforce training in advanced manufacturing.
Undergraduate Education• University of Dayton undergraduate students will be employed to work on testing and design guide development
phases; Inclusion of material in required seminar series for undergraduate mechanical and chemical engineering students.
Graduate Education• Design guidelines to be incorporated into new graduate course on AM at University of Dayton which will cover
analysis, design, and processing of structures using Additive Manufacturing.
Workforce• Contribution to the creation of an engineering pipeline that is prepared to meet the demands of designing
for Additive Manufacturing technologies.
Workforce and Educational Outreach
