I noticed that casting LDS in a foundry still uses the old recipe with molten iron, instead of titanium. Granted since there's no molten titanium, that doesn't quite work and I think it'd be less interesting to add a molten titanium that's used instead of titanium plates for other casting recipes... so I'm unsure. Maybe it costs vacuum AND titanium plates, so that it both costs titanium, and still has 2 fluids for input?

All that said, there being two different paths to LDS production IS interesting in its own right, and perhaps for some planet I haven't considered yet, it's important for there to be the two separate options to make progression feasible. Happy to defer to your thoughts here.

Thanks for raising this. Yes, I missed that recipe. I think your idea of using titanium plates and vacuum is a good idea, so I've made that change in the latest build.

And yeah, while I tend to agree having differing paths to making an item is often interesting when it has a purpose (Py has done this well in several places), with these mods I always try to stick to the "feel" of of the base game. For Space Age, I think having LDS rely specifically on titanium feels right.
