Topic: Bad filament surface at higher temps

Hey,

I have the issue that the surface of my ABS I bought from and injection molding company gets really rough when I extrude it over 175C. Its not really a problem it just looks weird.

I assume its an issue with that particular type of plastic, but I wanted to ask if anyone else has seen a similar thing with their extrusion.

This is pretty common with all ABS, though MG94 doesn't seem to do it until 200C or so. I am not certain if it is from moisture or melt fracture. Have you tried drying the pellets? What resin ID?

Hmm. It would be good to know, not only for expected extrusion properties but also for safety!
