Subject: Orbex unveils world’s largest 3D-printed rocket engine

UK-based space startup Orbex has unveiled the world’s largest 3D-printed rocket engine. The single-piece, cryogenic liquid-fueled engine is installed in the second stage of an engineering prototype of the company’s Orbex Prime launcher and is claimed to be more powerful by volume than many heavy launchers.

Could be safer as well as I imagine welds/joins would be a potential weak spot if not done properly.

Are they using CSIRO technology? CSIRO pioneered 3-D printing in titanium.

Note, much machining needed to smooth surfaces after 3-D printing.

Also, fingers crossed on the throat. That should be graphite, which can’t be 3-D printed.
