More specifically, GE noted that 855 conventionally manufactured parts had been reconceived as 12 additive-manufactured parts, including sumps, bearing housings, frames, exhaust case, combustor liner, heat exchangers and stationary flow-path components. </p> <p> <br /> </p> <p> In development since 2015, GE Aviation reported it has committed more than $400 million to the engine program. The R&amp;D program and testing have been carried out at GE Aviation’s operation in Prague, Czech Republic, where manufacturing of the new engines will be centered. </p>
