I didn’t know that they worked with polymaker for their ASA. I knew that Esun is their PLA/+ manufacturer though. I do miss those esun masterspools since they have switched to the cardboard spools. I’m glad that the spooless filament refills are still available. So far I’ve heard great things about atomic and I’ll have to give them a try. I also like overture a lot for their PLA and their PETG.
