Data from the dynamic scaling analysis of the growth front of silver patterns electroformed in a quasi-2D cell under localized and non-localized random quenched noise are reported. The plating solution either embedded in filter paper (FP), or containing disordered glass beads (GB), or as agarose gels (AG) were utilized. The scaling exponents from the displacement of the driven interface are α = 0.63 ± 0.05 and β = 0.60 ± 0.05 for FP, irrespective of its pore size distribution; α = 0.64 ± 0.05 and β = 0.58 ± 0.05 for GB; and α = 1.25 ± 0.10 and β = 0.88 ± 0.15 for AG. Exponents for FP and GB fit the predictions of the directed percolation depinning (DPD) model for D = 1, whereas for AG they coincide with those calculated by Leschhorn from a lattice model of probabilistic cellular automata. The difference between exponents resulting from FP, GB, and AG can be attributed to a non-localized random pinning in AG, which introduces a size-dependence mobility of obstacles in the gelled medium.
