Abstract
A method of forming a rotor for an ACM, having steps of forming a base having: a first section adjacent to an ACM diffuser shroud when installed; a second section forming a seal disposed against an ACM aft frame member when installed; a third section connected to an ACM compressor rotor shaft when installed; a fourth section connected to an ACM tie rod when installed; a fifth section between the second and fourth sections, forming the base includes: printing thermoplastic polymer surfaces from thermoplastic polymers disposed against each other, the thermoplastic polymer surfaces having different CTEs; forming a lower support section on the base by printing along the discrete sections a mixture of a third thermoplastic polymer and a catalyst formed with metal; and forming an upper support section on the rotor by depositing on the lower support section along the discrete sections, via electrolysis deposition, a metallic coating.
