SpaceX sent its first 3D-printed part into space early this year. The part, a rocket engine main oxidizer valve, flew aboard SpaceX's Jan. 6 launch of a Falcon 9 rocket carrying the commercial Thaicom 6 telecommunications satellite to orbit. The valve flew inside one of the rocket's Merlin 1D engines. [3D Printing In Space: A New Dimension

It would seem possible that there were 3d parts on the latest Falcon 9 rocket. I am long with 185,000 shares and intend to remain so well into commercialization. That being said I am looking for some insight from anyone who is somewhat familiar with what an oxidizer valve does and the likelihood that it would lead to the need for an abort of the rocket launch in a 3 engine assembly.
