well when you do a full lifecycle assessment you find something interesting:

But I am 3dprintingfag, not electriccardouche, so what do I know?

There are also new research fabbers being made capable of making precision investment casting molds for jet turbine blades.

If one's smart enough, it shouldn't be too hard to diy one.

There's really nothing to it. 3d printing is a new field, you could learn almost everything there is to know from a couple of books.

Well, if you're going to go indirect, you might as well just print the molds. One might be able to use a DLP projector to cure some resin mixed with alumina particles to make ceramic molds.

This has been demonstrated professionally and was shown to be precise enough to make molds for jet turbine blades. The process was so precise that a new file format had to be used, because STL just wasn't high resolution enough.
