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!

If the 3D printed components work, they may be cost competitive in the small satellite market.
