GE to build 3D made aircraft engine.
GE is testing its a-CT7 turboprop aircraft engine which will be made with about a third of its parts made through additive manufacturing processes.
The prototype replaces 900 conventionally manufactured parts with just 16, demonstrating the technology's power to create more complex parts than conventional means.
There will be components designed to finer tolerances or to withstand heat that ultimately may not be made this way, but the future looks additive.
