Starting from 1/2 way through rank 8, it took me approx 1500 duplicates, 300 cores, and 1m credits to max it out.

Obviously these numbers will change depending on what types of duplicates you have (a million and a half skill mods vs a million and a half crit modifier mods) and what types of cores you have (rank 3, rank 5, uncommon, rare, etc.).
