> I'm hoping for the next innovation with mixed extrusion to reduce print times. We are lacking an automatic extrusion amount and nozzle size mixing within a "layer". Not just fine layers everywhere with mixed colors on the inside.

The INDX has extremely low waste when you switch from one tool head to another. Just a little tiny nugget.

It also supports different sized nozzles in the different heads, like the Prusa XL.

So I suspect having far more people with access to that will help push better uses for that. PrusaSlicer 3 is coming soon with lots of improvements (according to them) but we don’t know what yet. I’m hoping that’s one of em.

Calling it "marketing" is a bit over the top. I understand what you're saying and your disappointment, but I think the issue is really a matter of unrealistic expectations.

The article is by Prusa Research and it's about a recent, novel 3D printing technique. This is very much an area of active research and also development (not to be confused with R&D).

The "FullSpectrum" thing is the name given to the project in which the developer, ratdoux, who is presumably an individual, demonstrated the technique. There's no Orcas in it, either.
