You talking about Gigantes Heavy Armor?
Very rare drop from the story fight with Gearworm where he uses it. The item is literally called 'Arsenal Core "Gearworm"' you just nab it and then you just craft it in the crafting menu in the factory where a new option called Heavy Armor shows up under items in the Development menu.
