    First I’ve heard of this company. If the 3D printed components work, they may be cost competitive in the small satellite market.

    Informative article, but it’s on a 3-D printing web site rather than a space web site. I expect that explains the one howler in the piece about the 2nd stage Rutherford engine weighing 23,000 kg. Looking at the Rocket Lab website, I see that the 2nd stage engine is said to have a thrust of 22 kN. Oopsie!
