Certainly. That's why I said "parts" and not "all".

What I meant is described in slightly more detail at http://arstechnica.com/science/2013/04/how-nasa-brought-the-... , in the section "3D printing goes to space"

> Using state of the art manufacturing processes where possible actually reduces cost—even if a newer manufacturing method is more expensive, the cost reductions gained from the design simplifications more than tip the scales. In particular, Dynetics and PWR are using techniques like selective laser melting and hot isostatic pressing (HIP) to "grow" entire complex engine parts out of metal powders. The Dynetics team is focusing as much as possible on reducing welds and joins, and therefore reducing assembly and manufacturing.
