This technical report presents FPP Térmico v3.0, a computational model based on First-Passage Percolation geodesics as a constructive principle for designing materials with programmable directional thermal conductivity. Key results: anisotropy ratios up to 985x, surpassing carbon fiber composites (60x). Includes 3D extension, inverse design, spatial correlation, and comparison with real materials including graphite and copper. Applications: thermal management for AI data centers, electronic components, directional heat exchangers, and aerospace thermal protection.
