Has anyone used ESUN PVA as support ?
In my project it’s just a mess, long strings and it ruined my project.
I tried to lower the temperature, but that didn’t help.
Maybe it’s because the trash is stocked, see picture…
It looks like the PVA sticks to the trash outlet.
I’ve just started playing with it. I believe mine is Sunlu branded but is likely the same/similar (it certainly looks identical to yours) I had to respool it to use in the AMS. I used the generic PVA profile. It does stick more than the PLA like you’ve discovered. There’s recommend settings that if you choose PVA for support in the slicer.
I confirmed the suggestion from the dialog, that didn’t help.
I set the temperature much lower (180 degrees), and the stringing was gone.
but it still not a success, the PVA does not stick well now, so I’m gonna set the temperature a bit higher to 190 degrees.
Mine PVA spool was to small for the AMS, so I made the 20 cm diameter one cm smaller with my multi tool and then I used a adapter to make the spool wider.
Make sure it’s fully dried before you use it , as it’s extremely hygroscopic (which is obvious, as it dissolves in water). And I’d only use it for the support interface, not the whole support. This will save on filament changes and the risk of stringing.
PVA needs to be dried
eSun PVA works well. I only use it for Support Interface
Generic PVA filament setting worked well on 0.4 mm nozzle with changes to nozzle temp to 190-210
On 0.2 mm nozzle @ .08 #Standard I use the following setting…
Speed slowed down support interface to 25
First layer to 25
First Layer Infill to 40
PVA material settings
Nozzle temp 190-215
Volumetric speed limitations 0.5
Hey, which settings do you use for the 0.4 mm nozzle? And how can I specify that I want to use Sun PVA, since Bambulab doesn’t have it listed as a filament? Should I just choose Bambulab PVA, or how should I proceed?
