The low warpage is insane.

This is a really awesome filament. Like other nylon filaments I've used, finished prints have a very nice slick dense feeling that other plastics like PLA, PETG and ABS just don't have. The feel is somewhat similar to Taulman Alloy 910. Polymaker claims that this filament doesn't really warp, and they are absolutely right. This filament just doesn't warp - at all. I have had one "failed" (meaning I couldn't use it, though the print did complete) print, due to the nozzle being too high, and the amount of warp I had due to the bottom layer being too far from the bed was roughly equivalent to what I would expect from printing PLA.

Right off the print bed, even small features feel extremely tough. This filament is no joke, and the inter layer adhesion is insane. Even features that are a single layer tall are incredibly robust.

The only thing to be aware of is that this is a Nylon filament - so you *need* a dry box/filament dryer. It will absorb moisture, and print quality will go down. It took me about 2 days to go through the 750g roll, and I decided to not put the roll in a dry box because I wanted to see what would happen. The first ~6 hours of printing were great, with no noticeable degredation of print quality. Over the next 12 hours, the prints I was running got more and more stringing, but it was never so bad that I couldn't clean up the print with a torch/xacto knife afterwords, so I left the filament out of the dry box. So ultimately, if this filament is nice and dry, it will print basically like PLA. It's just as easy, can be run fast (I'm running this on my Voron Trident at 150mm/s and 6700mm/s^2 acceleration, and layer adhesion is not a problem at all), and looks amazing - again, just keep it dry.

I will absolutely be buying this stuff again. I bought the "natural" color, as I'm 'dyeing' (get it?) to see how dyeing the parts I've printed goes. Supposedly RIT liquid fabric dye works well with nylon 3d prints, so that's what I'm going to try.

Oh, and a note on annealing. I haven't tested strength before and after, but annealing doesn't appear to cause the print to change in appearance as some other filaments do. I've done it on my prints because I want the 180C heat deflection temperature, but the parts feel just as solid to me both before and after annealing, so YMMV.


In case you're wondering about the preview image, it's correct. You actually get 0.75 kg (750g).

I do think the filament is interesting though. It's about as easy to print as PLA. Sticks right down and stays stuck. Right after printing, it has a somewhat slick feeling, but it also feels dense. Maybe like ABS? After annealing, the resulting product feels both sturdy and lightweight. Umm, like holding a hollow charcoal briquette (I was printing a motor housing for one of my voron's feet)

Even though it says you do not need one, I would recommend the enclosure. This filament gives off an unpleasant odor as it melts. After thinking about it, it smells very similar to mulch (not the nice-smelling pine kind, the sour-smelling one soaked in liquid fertilizer or something)...so having something to keep it isolated will help your sanity. Or maybe the reason why I could smell it is because I kept the fumes in a small box and let it concentrate since I've seen others claim that this should give off less odor than PLA. Not sure.


PolyMide™ CoPA is based on a copolymer of Nylon 6 and Nylon 6,6. The filament combines excellent strength, toughness, and heat resistance of up to 180˚C. 
  • Does PolyMide™ CoPA requires an enclosed printer?

No, all our Nylon features our Warp-Free™ Technology which means it does not require a heated bed or heated chamber of more than 50˚C.
PolyMide™ CoPA can be printed on a 30-40˚C bed without enclosure.

  • Do you need to anneal PolyMide™ CoPA?

PolyMide™ CoPA displays outstanding mechanical and thermal properties when fully crystallized. The printed part will not reach full crystallization after the printing process, an additional step is required: Annealing.
You can anneal PolyMide™ CoPA by placing your part in the oven at 80˚C for 6h.
