Strontium aluminate - REE glow filament

[ken cummings]

I've read that the older zinc sulfide glow filament glows less and for less time than filament using strontium aluminate. Both use traces of other elements like copper for red glow in zinc or certain rare earth elements in the Sr-Al stuff. Oh, ZnS filament is much cheaper. So where can I get the good stuff? As well as hardened nozzles so I don't rot out the nozzle printing the stuff.

I'm not sure about stock hot end as I've moved to E3D, but they have hardened steel nozzles.

I only found this article today it was an interesting read - http://e3d-online.com/blog/is-carbon-ki ... our-nozzle" onclick="window.open(this.href);return false;
