Comment on Chonky nozzel + decent amount of material = opportunity for lots of spaghetti
IMALlama@lemmy.world 1 month agoPolymaker ASA is what I’m currently using. You can grab 3 KG spools on Amazon for as low as $50-60 depending on the color (new via prime) if you keep an eye out.
The mix of ASA and a higher flow printer as resulted in a lot more fickle prints though, but this is also true for PETG. Things like EM vary some as a function of speed, so I’ve found that I need to print all my features at a similar speed.
Thx! Sounds like rly good deal, but 3 kg is not for me honestly. I dont print that much and also my spool holder is too small. 500 g spools would be better for me hehe
Not sure what EM is, but if you meant that some parts of print are shiny and the rest is matte, its probably different flow. Having equal speeds should fix that, I saw a video where they reduce max flow as solution
EM means extrusion multiplier, which is also called flow in some slicers. Shiny vs not is usually a temperature thing.

Total anecdote, I had nothing but problems with Polymaker ASA, which I believe was me trying to run it through too fast. i have a dragon UHF which is, in theory, supposed to be able to do speeds over 30 mm^3/s, first thing I’d try is just slower print speeds and then bump it up from there.
You could also look at a cht nozzle, but as a word of warning, I found the bimetallic ones super fragile, if I recall they want a way lower torque spec than a solid brass or steel nozzle, so they’re easy to shear off if you’re not careful.

What kinds of problems have you had? It’s been OK for me. Sure, it’s harder to print than PETG but it’s also ASA. I do find myself wondering if it’s the material or my setup at times though. So far I’ve run about 7 kg of the stuff. You can find a bunch of it in my post history.
What did you switch to?

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.

Thanks for the reply. I haven’t had clogging issues with it, but I have had some whispy stringing until I lowered my temp a touch. My preferred filament house (Atomic Filament) looks like they’re offering ASA so maybe I’ll give them a shot. My biggest issue is warping and I can’t imagine that other brands are going to be that different. I finally got great bed plate adhesion but my last print pulled the magnetic surface up.
