Hi folks. I obtained a pre-owned Anycubic Vyper. Alas, every print features defects in the surface as shown in the picture. It occurs in any type of material. Does anybody know the source of this type of defects?
Wet filament. Or. Bad filament.
Those are bubbles. Try a dryer.
I already got myself a dryer as I suspected that. But this occurs in multiple filaments, brand new and older ones, different brands. To me it somehow feels like this is not the root cause… But I’ll keep an eye on that.
Do you live somewhere humid right now?
Central Europe. I’d say it’s not too bad, but the printer is in a basement which tends to be humid…
This is also my take on it.
I got results kinda like that before when I tried a Volcano on an old Bowden style printer and printing wet PETG… Tons of oozing.
Well, the PETG is brand new and I use a heated chamber for the filament, so I really hope this is not the case. But as the setup sits in a basement, I’ll try to check that, too.
Did you dry your filament? How old is it? Did you get all your filament pre-owned as well? Depending on the kind of material, it has a limited shelf life, once you get beyond that it won’t ever print right.
Try some brand new filament and see how that works.
The filament is brand new, I also tried other brands and types of different age so I assume it is independent of the filament.
