Polymaker Nylon Filament 1.75mm 0.75kg Black CoPA, PolyMide CoPA Warp Free Nylon 3D Printer Filament, Strong & Tough & Heat Resistant

This stuff is amazing. Nylon that has no fibers and still doesn't seem to warp like mad or absorb water like it's dessicant. It prints effortlessly for nylon. This will be my choice for plain nylon from now on. Very nice work Polymaker!

I don't know what black magic polymaker shoves into their filament, but holy crap. I've used their straight polycarb, it's good. I've used their PC-MAX, it's awesome. I've used some off-brand PA-6 CF, it was a'ight. This stuff? I didn't do any calibrations, any prep, I just threw it in a drybox, dried it for 12hrs, and tossed it on my prusa mk4 for a benchy so I could start calibrations. Their claims of "don't heat the heatbed" had me weirded out, but whatever, it's my first print. It's like the first pancake of the batch, it always gets thrown away. That benchy came out *perfect*. I couldn't believe it, so I ran a stress test. Perfect 65° overhangs, minimal stringing, it never even treid to let go of the PLA temp bed. Once my 100g sample ran out, I flew over to amazon and ordered 2 spools of this stuff, and it's been magical ever since. If you need to print nylon, and you don't want to suffer with all the quirks and weird build plates, this stuff is WELL worth the extra money.

this nylon works great, i had to print a large flange of 22" in dia on an open printer and this printed great, no curling, no delamination and also the part came out super tough after some days of acclimating. highly recommend

Make sure you have a way to dry the filament before you order it. I was a little nervous to print nylon. My dad needed a part that kept breaking in PLA, PETG and ASA. I printed it in CoPA, annealed it and it has held up great for a year. I used the rest of that spool making parts for an RC car that worked great. I've always kept a spool of this on-hand since. Polymaker makes the best filament overall, but you do pay a bit more for it.

No problems, prints beautifully like it should. Prints good from my Qidi and my Bambu lab

Copa took a bit to dial it in but wow this is strong stuff and prints smooth.. But doesn't like overhangs much.. Could be in my settings tho.. As most know every printer is different with settings..I turned up my feed rate to 115% and made a huge difference in layer adhesion and Wall adhesion. Using the creality spider hot end and simplify 3d slicer.. And printing at 240 temp.. .24 up to .32 layer thickness

I was really impressed with the PETG ESD. It was nice having something a choice in the ESD line with without carbon fiber to obtain that nice shiny smooth surface finish you often give up to a certain degree with carbon fiber filaments. Fit my application nicely. Easy to print and I used temps of 60/280 which were provided through the slicer filament profiles on the polymaker website. Despite the manufacturer box recommending a bed temp of 70-80 the provided profiles worked perfectly. If you read alittle bit more into this product you'll find polymaker mentions this product is more and more effective/ optimal the higher the nozzle temp so I didn't shy away from what I initially assumed were high temps. Great product and I already bought more. Not one failed print yet.

Filament came in well packed. Just to be sure, I baked it overnight at 55C (max dryer temperature). Later on during printing, there were no hissing or popping noises so it was truly dry. I started with the recommended 260C nozzle and 45C bed settings. After the first few layers the extruder starts to make creaking noises and skips. Upon inspection I could see a few ground out spots on the filament. Temperature was raised to 270C to improve the flow. Still no go. Model changed to reduce retractions. Still no go. Checking the filament movement, it seems as if the flow gets restricted now and then and extruder fail to overcome it. Increasing spring tension and “helping” the extruder improve things somewhat but not enough to finish a print. Partial clogging? Extruder is Micro Swiss bowden dual gear. It is calibrated and does not any problems with other filament: various PLAs, PolyMax™ PC, PolyMide™ PA6-CF, etc. Suspecting there might have been a fault with the printer I swapped Polymaker CoPA for the old trusty Taulman Alloy 910 and the exact same g-code completed just fine. I did manage to complete one part and it came out strong, with decent finish and slight warp. No problems with the first layer or inter-layer adhesion. So, I suspect if you manage to print it, the parts would be, as expected, quite strong. As for me, it is back to Alloy 910.

Filament faible à imprimer mais relativement déçu du rendu. J’ai choisi ce filament pour ces capacités thermiques. Il supporte bien les hautes températures une fois imprimé. Je n’apprécie pas le rendu qui n’est pas lisse. Je recommande plus volontiers du PACF PAGF qui s’impriment bien avec un bon tendu et une excellente résistance thermique aussi.

I have run a few pounds of Taulman 910 and it is good stuff but it is way overpriced on Amazon and my regular vendor was out. This stuff is every bit as good in my opinion and is a little more stiff which is beneficial for what I do with it.

Tres bon produit
