The International Space Station (ISS) , managed by HEOMD, is the prime candidate for advanced concept technology demonstrations of space-based additive manufacturing technologies, processes, and products, as well as an initial test bed and staging platform for utilization and optimization of products developed with space-based additive manufacturing.

Most recently, NASA Ames Research Center, in collaboration with San Jose State University students, successfully launched the first CubeSat from the ISS, TechEdSat. Other centers, particularly JPL and GSFC, have begun to place particular interest on use and application of smaller satellites and nanosatellites, for both early stage technology demonstration, as well as to implement science missions, possibly including future interplanetary and deep-space nanosatellites.

Additionally, because the focus of SSTP is on development of the satellite subsystems and integrated technologies from the platform standpoint, emphasis and focus on specific enabling technology areas necessary for additive manufacturing do not get specific and focused visibility. As the use and application of CubeSats/nanosats matures and expands from university aerospace education and technology demonstration efforts to peer-reviewed science and technology and specific mission applications, their utility, awareness, and acceptance as viable platforms is becoming increasingly evident in both NASA, DOD, and other government agencies, as well as commercial and entrepreneurial space markets.

FACTORS AFFECTING THE USE OF ADDITIVE MANUFACTURING FOR NASA SPACE MISSIONS Previous chapters of this report discuss the many different additive manufacturing techniques, methodologies, and capabilities now being undertaken worldwide. There are four fundamental factors that will likely have the strongest influence on the future use of additive manufacturing in NASA space applications.

The committee was impressed with the number of ideas and potential uses for this emerging technology. Although it recognized that some of the ongoing research is proprietary, the committee concluded that there are many people and groups that could benefit from sharing ideas and making contacts while identifying the unique challenges associated with space-based additive manufacturing.

highlight 14 critical technology areas, including those necessary to facilitate robotic human exploration beyond low Earth orbit. The roadmaps target timelines where technology development is needed to enable space exploration, and one of those specifically discusses advanced and additive manufacturing.

NASA should build on the considerable experience gained from its Space Technology Roadmaps. The space-based additive manufacturing roadmap objectives should include, but not be limited to the following: • Developing goals for using the technology to assist the agency in meeting its key missions, covering all appropriate mission directorates, especially long-duration human spaceflight and planetary operations, by defining, understanding, evaluating, and prioritizing the direct and supporting technologies for autonomously or minimally attended space-based additive manufacturing and robotic precursor and free-flyer missions; • Identifying flight opportunities, such as on the International Space Station during its next decade of operations; • Targeting the full technology-development life-cycle and insertion strategies through 2050, aligned with target agency missions, for all appropriate mission directorates and related collaborations; and • Ensuring that support for incremental advances to address the technical challenges is supplemented with support for activities related to reaching the full potential of additive manufacturing.

In some cases, the options and trade-offs will be based on operational, cost, and logistical concerns. In other cases, it will become increasingly essential to have space-based additive manufacturing capabilities to support NASA's orbital, lunar, Mars, and deep space endeavors beyond low Earth orbit.
