Regrettably the knowledge to build a Saturn V was not captured. To do it again would be a lot of starting over.
The Saturn V was primarily constructed of aluminum. It was also made of titanium, polyurethane, cork and asbestos.[54] Blueprints and other plans of the rocket are available on microfilm at the Marshall Space Flight Center.[https://web.archive.org/web/20100818173517/http://www.space.com/news/spacehistory/saturn_five_000313.html]
However, it is the unwritten knowledge and experience that engineers etc. attained that is not captured.
