Abstract
A turbopump is formed from a metal additive manufacturing process in which both the housing and the impeller are formed as a single piece with the impeller trapped within the single piece housing. The impeller is formed with an axial bore and a shaft is secured by a tie bolt on one end to secure forward and aft bearings within the housing after the impeller and housing have been formed.
