To preserve national security, the United States Navy must continuously explore new technologies that can enhance warfighting capabilities, increase weapon system readiness and operate in a narrowing fiscal environment. The high cost of sustainment of military systems, coupled with extended life cycles, has compelled the Department of the Navy to find innovative ways to sustain in-service equipment. Additive manufacturing, also known as 3D printing, is one technology that demonstrates potential to provide novel warfighting capabilities and reduce sustainment costs of military weapon systems. But how can the Navy leverage the cost savings and lead-time reductions promised by additive manufacturing and simultaneously minimize the risks associated with a rapidly evolving technology? This thesis explores the technical and logistical factors necessary to identify applications of additive manufacturing for sustainment of in-service naval aviation equipment. The thesis introduces a component selection methodology to query the aviation spare-parts inventory for identification of additive manufacturing candidates. The methodology organizes the resultant data using a top-down approach that aligns technical feasibility with programmatic objectives. Finally, a discrete event simulation (DES) in Innoslate analyzes the data to provide engineers and logisticians with a decision-management framework to support the development of a business case for additive manufacturing.

Additive manufacturing (AM) has been proven to provide multiple benefits over traditional manufacturing methods including cost-savings, mission adaptability, and increased unit capabilities. Multiple Department of Defense (DOD) organizations are exploring and utilizing AM technology, and efforts are ongoing to determine how best to achieve large-scale adoption of AM in the U.S. Navy (USN). The primary concern that must be addressed is the trustworthiness of AM objects to ensure they will not increase risks to personnel, equipment, and systems. Including cybersecurity throughout the AM life cycle is a necessary component of protecting AM data and ensuring trust in AM objects to support adoption. This thesis reviews aspects of cybersecurity domain as it is applied to AM, and discusses the insights of a survey conducted with USN, U.S. Army (USA), and U.S. Air Force (USAF) resident NPS students. The goal of the survey was to contrast current understanding of adoption of technology and cybersecurity threats in AM, with the knowledge, attitudes, and opinions that prospective users have. The thesis identifies barriers to achieve large-scale adoption of AM in the naval domain with special emphasis on cybersecurity, and proposes approaches to address those barriers and support accelerated adoption of AM.

Additive manufacturing (AM) for space exploration has become a growing opportunity as long-range space missions evolve. In partnership with the National Space Grant Foundation and NASA, students from the University of Wisconsin-Milwaukee participated in the 2014-15 X-Hab Academic Innovation Challenge, with participants tasked with developing new AM solutions that would be recyclable with minimal loss in mechanical properties. The teams investigated materials, characterization, testing, modeling, and tool development, including the ability to employ reusable carbon-fiber tension ties. The tools developed show that it is possible to employ thermoplastic polymer materials fabricated using AM together with reusable and flexible high-performance carbon-fiber-based composite ties. The AM-printed part is completely recyclable. The carbon-fiber composite ties are repurposed into new structural configurations without loss in properties. The results of this project are now published by SAE International. Studies into Additive Manufacturing for In-Space Manufacturing is a series of interconnected papers that explore: Lessons learned in processing of recycled thermoplastic filaments The criticality of process control on the print process The effects of orientation angles and print parameters on mechanical behavior Microstructural analysis Case studies of tools included in the spacecraft's toolbox

In the coming decades, the growth in AM will likely be driven by production parts that leverage this increase in design freedom to manufacture parts of higher performance and improved material utilization. Contrary to popular opinion, however, AM processes do have their constraints and limitations - not everything can be manufactured with AM, and even when it is feasible, not everything should. Design for Additive Manufacturing: Concepts and Considerations for the Aerospace Industry, edited by Dr. Dhruv Bhate, is a collection of ten seminal SAE International technical papers, which cover AM from the perspective of the appropriateness (should) and feasibility (can) of using AM for manufacturing of parts and tooling. Although AM technologies have been around for three decades, many in the industry believe that we are merely at the beginning of the revolution in the design-driven aspects of this technology. Indeed, half the papers in this selection were published only in the past two years, and all but one in the past decade. When it comes to design for AM, it is a safe bet that the best is yet to be.
