From what I read on the crafting page and result logs on JP wiki, Bismarck can be crafted using Base default recipe but you need at least 20 dev mats, higher chance comes with the Yamato recipes. Also having Z1 or Z3 as flagship may increase chances but it is possible to get her without having them as flagship(there is one guy who managed to get Bismarck with Yamato as Flagship).

Whether 20 Dev mat is a must or not, I'm not sure since I've yet to see anyone managed to get her using base recipe and 1 mat, although there are a few cases with base recipe and 20 mat.
