Quality Metal Additive Manufacturing (QUALITY MADE)
Unclassified
EPE-FY17-03: Quality Metal Additive Manufacturing (Quality Made) Additive Manufacturing (AM) is a disruptive new manufacturing process that will enable reliable & cost effective low volume manufacturing to increase Fleet readiness when
- appropriate. While early AM adoption is currently being used or
explored across the Naval Enterprise, technology development is still necessary to realize AM's full potential for metallic components, to improve designs, to reduce manufacturing cost/waste, and to increase the quality and reliability of manufactured parts. This EC will develop technologies that provide a science based approach to AM design optimization and process control and allow for increasing the size and complexity limits of AM systems. These technologies will be demonstrated to a TRL 6 by AM fabricating parts that are currently cast and by rapidly manufacturing complex molds for use in casting. Castings are a high value target for AM because
- f their complexity, high initial investment cost and their wide
spread use across Naval platforms. The use of additive manufacturing technology to manufacture metal “on demand parts” can enhance operational readiness and reduce the total

EC Metrics: Program Level:
- Increase platform availability by reducing part acquisition time (Mean
Logistics Delay Time) from 8-28 months for one-off parts, low-volume, crash damage, and red stripe parts* by 50% (T) and 80% (O). * 8-28 Month Baseline established by NAVAIR review of DLA data on multiple
aircraft for low volume production runs and out of production parts. Also represents 50% reduction in part manufacture from 19-95 weeks.
- Reduce time/cost to design and optimize AM replacements for cast
components by 30% (T) and 50% (O). Eliminate need and cost for special tooling/casts for applicable parts. Baseline is current cost/time to procure cast parts. S&T Product:
- Process capability 2σ for tensile properties with closed loop process
control [P (LSL ≤ x ≤ USL)≥95%]; (O) 3σ or ≥99.7%
- Microstructure-Property Prediction Capability as a function of process
and geometry: +/- 10% (T) and +/- 5% (O)
- ICME & processes developed for selected materials: 2 alloys - Ti-6Al-4V
and Al-Mg-Si using 2 metal AM processes (T), 3 alloys to include the addition of Steel (O)
- Uniformity of Microstructure (by % volume): 90% (T) and 95% (O)
Demonstration Parts:
- Defects (Porosity, Lack of fusion) - Size and Number: (T) Match that of
Castings and (O) 25% Improvement over Castings
- Mechanical Properties: (T) Match that of castings and (O) Meet or
Exceed AMS for selected materials
- Fatigue Properties: (T) Match that of castings and (O) Match wrought for
selected materials
