A key issue for high av­er­age power, nor­mal con­duct­ing radio fre­quen­cy (NCRF), pho­toin­jec­tors is ef­fi­cient struc­ture cool­ing. To that end, Ra­di­a­Beam has been de­vel­op­ing the use of Solid Freeform Fab­ri­ca­tion (SFF) for the pro­duc­tion of NCRF pho­toin­jec­tors. In this paper we de­scribe the pre­lim­i­nary de­sign of a high gra­di­ent, very high duty cycle, pho­toin­jec­tor com­bin­ing the cool­ing ef­fi­cien­cy only pos­si­ble through the use of SFF, and the RF ef­fi­cien­cy of a re-en­trant gun de­sign. Sim­u­la­tions of the RF and ther­mal-stress per­for­mance will be pre­sent­ed, as well as ma­te­ri­al test­ing of SFF com­po­nents.
