Spray Casting Is Attractive Fabrication Process for Outer TF Shell
Molten alloy metals just above melting point are atomized and sprayed onto a preform to fabricate the part
Fast deposition rates (0.5 kg/s/head with 4 heads)
Minimal labor required with computer control
Detail is less than laser forming (probably will need final machining on mating parts)
Stainless steel coolant tubes can be embedded
