Strontium aluminate - REE glow filament
Posted: Fri Apr 01, 2016 10:22 pm
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.
