#Weird pattern with Polymaker ASA

The last few days I was trying to find the correct setting for the extrusion multiplier to print Polymaker ASA and besides a couple other problems, I noticed a weird pattern while printing. I checked many different slicer settings, printer settings, hardware changes etc and nothing really helped. Today someone recommended that I should try a different filament and after doing so, everything suddenly changed. It seems like when I try to print the black Polymaker ASA, as well as the white ASA (different) I get weird textures on my lines while other filaments don't seem to have that problem. On every second line of the top of the EM cube you can see weird "cracks" along the lines. When I try the white ASA those cracks disappear but it looks like the lines are made out of blobs (or almost braided) instead of being a smooth line. When I use other filaments (e.g. eSUN ABS+) the lines become super smooth and the problems seem to be gone. I tried temperature ranges between 245-260C and the results are always the same. Is there anything else that I can do, to fix this problem and make it possible for me to continue using Polymaker ASA?

The 2 photos of the black ASA are from 2 different spools, purchased at different dates which shows that it is also not a spool specific problem, they are from the same batch # though

Looks like moisture bubbles. I’d start by drying the filament

The second pic is from a spool that was in a food dehydrator at ~70C for ~10 hours

#

The first one was fresh out of the packaging

#

White was dried for ~3 hours

I'd also recommend drying. Just because it's fresh out the bag doesn't mean it hasn't gotten moisture at one point or another. That goes for any filament.

How much longer should I dry it to expect a difference haha

I read that wrong and that you were comparing the esun that was dried and the fresh out the bag polymaker.

Since you did dry it, I would say it could be a temp setting and may need to adjust accordingly.

The temp is more dependent on the flow rate you’re trying to achieve, than the mfg recommendations.

I set a limit to 10mm3/s on my Revo and the top layers are printing at 60mm/sec which is way below the maximum volumetric flow I set which is already below what the Revo could handle

Just for fun, have you tried a different nozzle?

Yes, I did switch to a brand new Revo nozzle and had the same results. That was one of the first things I tried because I thought it might be scratching the filament 😄 It wouldn't really work that way though knowing that other filaments work fine but I tested that a lot later

Try +/- 10-15C on your nozzle, I've found that darker filaments need a higher temp a lot of times. I have to run blue filaments the hottest it seems

I know LJ on the voron discord uses it as the pif primary color with success. So must be this one batch. 2 others were mentioning this batch in the voron filament discussion

If you haven't already, at this point I'd submit a ticket in #open-ticket
