Despite considerable advancements, elucidating the connections between nanoscale architecture and macroscopic mechanical properties remains a complex challenge. In this study, we employ cryogenic 3D X-ray ptychography alongside \textit{in situ} mechanical testing of nanoarchitected pillars (diameter of approximately 40 micrometers) to illuminate the intricate interplay between morphological features and mechanical response in scalable polymer-based nano-architected metamaterials. These materials, endowed with features on the order of (approximately 500 nanometers), were created using metasurface enabled holographic lithography, and exhibited specific energy absorption in the order of 48 kJ/kg. Our analysis revealed a pronounced correlation between two spatially separated deformation modes, specifically barreling versus layer-by-layer collapse, and the principal curvatures inherent to the material's nanoscale architecture. This morphological variation demonstrates the feasibility of scalable functionally graded nanoarchitected materials with holographic lithography.
