I had clogging and stringing issues, which not unexpected when jumping between materials. I had tried it to reduce smell, but ended up not finding much of a difference for me. Prusament ASA was decent but really expensive (duties alone). I probably didn’t give it (polymaker) a fair chance, had really good results with the polymaker pla and polyterra pla for some decorative prints. I’ve definitely had my share of hit and miss with amazon filament, they certainly are way better than I recall them being a decade ago, I do try to dry them now before using and stick with a few brands. I may also be misattributing issues to the polymaker asa, I also bought esun abs+ at the same time, I was building a nevermore max, one of the two just gave me grief and I was mildly annoyed with failed prints.

In terms of what I use now, I have had a lot of luck with Spool3D abs and petg, I sourced a lot of parts from them and found their filament pretty solid (though I’m not sure who supplies it). Recently I’ve been using Matter3D abs and pla, they have a wood fill pla I liked and their abs printed nicely for me. I’m Canadian so import duties and shipping can be killer, so trying to find a domestic supply was my goal. I definitely still use polymaker, have used a bunch of standard abs and their colour selection is amazing. I don’t tend to go for asa over abs, if only for price, looking at amazon, for polymaker 2x1 kg black is $55 cad for abs and $77 cad for ASA, I can almost get an entire third spool for the difference in price.
