Tungsten PETG autoclaving test
Now Prusa never said you could or could not autoclave the PETG/Tungsten, so more out of curiosity we tried a part, which as you can see here, melted into a blob (I have autoclaved lots of printed parts in nylon 910, polycarbonate plus of course many SLA resin prints and never had a problem, so was somewhat surprised that 115C steam would melt it so readily, I suspect unlike normal plastic the thermal mass of this is so high. Oh well, no big deal, but was a useful test to know if you could anyway? And before someone goes off on a tear about how 3D printed ridges can't be sterilized, thanks, we have a large infection control team who test the autoclaved parts and this is for a lab experiment anyway, and we've had plenty of success sterilizing nylon prints in the past, which is why autoclaves work so well is they use pressure to force the steam into crevices (not like our surgical instruments don't have tons of nooks and crannies also!)
