Can you tell when the dry filament started being extruded?
(lemmy.dbzer0.com)
This particular filament (Sunlu matte HS PETG) is one of the absolute worst I've ever used WRT being hygroscopic. It arrived so wet that I had literal steam from the extruder the first time I wanted to use it. It took almost 48h in my drier to dry it completely so I could use it. Its been sitting in an airtight box with dessicant for 5 weeks and I needed to dry it for >16h for it to be usable again. The wet part in this print was in the bowden tube between dryer and printer, I restarted the print after took this image.
Sure it prints well at 300mm/s, but it is by no means matte at the temperatures that allow printing it at high speeds, it is actually very glossy. A huge bummer.
smooth first layer...so nice
I've never seen a PETG that isn't glossy. Maybe this stuff is so hydrophilic that the little time it spends outside whatever storage environment you have allows it to get really wet?
Probably not, I've seen reviews online (after I bought it) that complains about it only printing matte at lower temperatures but then is isn't possible to print fast anymore.
