Description

3D-printed with selective laser melting, this Additive Manufactured version of the injector showerhead used inside combustion chambers manages to reproduce a complex internal geometry, subsequently passing a pressurised leak test. The standard version requires more than a hundred separate welds to produce, done without in this AM-version. The main remaining challenge has been to produce holes of the correct size required, currently requiring secondary processing to achieve.
