Technical Abstract (Limit 2000 characters, approximately 200 words)

IERUS Technologies proposes to investigate utilization of additive friction stir deposition (AFS-D), to robotically fabricate and repair large structures in the external space environment. The AFS-D process, commercially known as MELD, provides a new path for coating, joining, repairing and additively manufacturing metals and metal matrix composites The MELD process produces fully-dense, near net-shape structures in open atmospheric conditions without secondary post processing. MELD is a fast, low-power, fully scalable, deposits almost any metal on the market and builds complex 3-D structures without support material. MELD also offers a unique opportunity for in-orbit recycling applications. The MELD process is a capable platform for recycling, using scrap metal chips and damaged components as feedstock to additively manufacture new. MELD could be the technique that unlocks in-space manufacturing potential while simultaneously mitigating orbital debris. The MELD additive manufacturing technique is well suited for on-orbit manufacturing and will bring tremendous advantages.

Potential NASA Applications (Limit 1500 characters, approximately 150 words)

The advantages of the proposed In-space manufacturing stem include the ability to manufacture larger structures, lower launch costs, increased performance, longer satellite life, increased resilience, simplified logistics, and more sustainable spaceflight operations. NASA needs to be ready to move forward and continue scientific and technological advancements by proceeding with in-space manufacturing efforts now.

Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words)

Commercial markets such as SpaceX’s Starlink satellite constellation are emerging that could greatly benefit from the proposed in space manufacturing concept. There also is a continued and constant interest for a commercial space station, that would undoubtedly need in-space manufacturing technologies in order to be successful and reach its true potential.
