Zipp - hand built?

Hi all. Potentially a stupid question but here goes anyway…

Are all Zipp wheels hand built? Or specifically the 30 Course disc tubeless?

Thanks in advance.

Thanks Richard. The 30 Course is aluminium though and at the budget end of Zipp’s range so I’m not sure the techniques are the same.
