Abstract
A method of fabricating a tank includes connecting a pressure source to a nozzle on a male mold, inflating the male mold via the nozzle, forming a tank by applying at least one layer over the outer surface of the male mold, the tank having a port formed about the nozzle, deflating the male mold, and withdrawing the male mold through the port. A method of fabricating a tank includes 3D-printing a male mold, connecting a pressure source to a nozzle on the male mold, inflating the male mold via the nozzle, forming a tank by applying at least one layer over the outer surface of the male mold, the tank having a port formed about the nozzle, deflating the male mold, and withdrawing the male mold through the port. A method of fabricating a tank includes forming a tank on a mold formed from a foam blocks.
