TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Large solar arrays (100 kW-1 MW) are required in order to generate the power necessary for solar electric propulsion to drive NASA's future missions, including: Asteroid Redirect Mission, Mars Exploration, and NASA Commercial Supply. The advantages and benefits of large solar array designs will only be realized if the array support structure weight and packaging volume are minimized. SDC's Advanced Composite Truss (ACT) additive manufacturing technology can provide a 30-40% weight savings and a 250-300% improvement in power per unit volume over existing state-of- the-art solar array boom structures. The ACT technology consists of the lightweight advanced composite truss, the autonomous low-packing volume ACT printer, and an integrated solar array deployment system. The weight of the ACT structure is designed to optimize the load carrying path within an open truss architecture. The material for the truss is efficiently packaged within the envelope of the ACT printer prior to launch. Once in orbit, the ACT printer autonomously manufactures the ACT structure without the need for mechanical joints. The ACT printer can be scaled to manufacture any size, length, and/or geometry truss required to meet the prescribed mission requirements. Following the manufacture of the ACT truss, the integrated drive system of the ACT printer autonomously deploys the solar array.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The primary market for the ACT additive manufacturing technology is large (100 kW-1 MW) solar arrays. However, the ACT system is reconfigurable, scalable, and reprogrammable, making it applicable to a large number of other space applications. The ACT system could also be implemented for structural reinforcement for the ISS or other space structures, structural booms for solar arrays on lightweight space structures, Mars colonization infrastructure, straight and curved primary structure on satellites or future space stations. SDC estimates that the ROI for launching the ACT system on five (5) different missions will exceed 3. The ACT system has direct applicability to the asteroid redirect mission, the Mars Exploration missions, and NASA commercial resupply missions.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The ACT system is being developed with complete printer and structure tailorability to meet a range of mission objectives. Additional applications include private space exploration spacecraft that employ solar electric propulsion, private space stations, and terrestrial applications including low wind resistant booms, light weight antenna structures, and tether satellite structures (electrodynamic and moment tethers). SDC estimates that if the ACT system could be utilized in a production environment (either in space or on earth), ROIs of 10-100 could be realized.
