Abstract
ABSTRACT Selective metallization is not be a new concept, but when applied to three-dimensional (3D) geometries, numerous challenges are apparent. Various approaches are explored for utilizing additive copper plating techniques to achieve selective metallization on complex two-dimensional (2D) and 3D structures. With a focus on enhancing the manufacturing of conformal antennas, frequency selective surfaces, and flexible hybrid electronics, this study evaluates three additive copper plating methodologies, coupled with subsequent selective plating and etching techniques, to achieve precise metallization control. Each process implements a unique way to additively build up copper, including electroless copper plating, deposition of conductive inks, and sputtered conductive coatings. Through an investigation assessing each strategy on various materials, key variables were identified to enable accurate and repeatable selective metallization. Building on this success, the approach will be evolved for 3D substrates, establishing a foundation for the creation of intricate conductive patterns on complex shapes. Furthermore, this process will be developed for maturation and scalability in manufacturing, with a focus on applications in the defense industry, enabling the production of complex conformal electronics with enhanced performance, reliability, and efficiency. The results of this study have significant implications for additive electronics, providing new opportunities for advancements in manufacturing of conformal antennas, frequency selective surfaces, and flexible hybrid electronics, and enabling the creation of intricate conductive patterns on complex shapes.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
