In my quest to find new and interesting things to print with I purchased a spool of Kodak Nylon 6 in blue from amazon and ordered a spool in black directly from Kodak. It is a 6/66 copolymer and it sounded like it could possibly be a competitor to the Polymaker CoPA which I love to print with.
Long story made short... Don’t do it. It came out of the bag looking like it was wound onto the spool by a bunch of pre-schoolers during arts and crafts time. I can’t even talk about how it printed because I never got that far. It looked like 10 pounds of crap stuffed into a 5 pound sack just sitting on the spool. It got hung up on the spool during filament loading because, well dammit I paid good money for this stuff I wanna see what it can do. Nope it dragged the spool out of the spool holder in the dry box. The raw filament seems to be quite strong, maybe I can use it to refill the weed eater.
I saw some ads for the Kodak filament and my impression was that Kodak was probably not actually making it, but reselling it as a 'test the water' entry to the 3d printing supplies market. From your photo, it was probably respooled from larger lots, and possibly by makeshift equipment. (LOL, electric drill?) 😉
Thanks for the report. I'll know to stay away for now.
Physically it's kind of like a TPU, a little soft, yet at the same time when I pulled out a piece that was about 3 feet long I couldn't get much stretch out of it using my hands. A lot of filament will just break when i do that. I was really looking forward to printing with it. If I can find the time and the patience, I'll try to respool it onto an empty spool. I'd really like to try it, but at this point it will be a month or two down the road because I'm just disgusted with it right now.
Too much water?
Dry it in a oven.
Good to know, how is PolyMide CoPA performing for you?
I have had good success with Kodak's Orange PLA. I have printed several rolls without a single bad print that was not self-induced. I have also printed a single roll or yellow translucent PETG from Kodak with great results. Kodak's 6/66/12 Nylon was more challenging. I printed for 2-3 days without success. I finally received good results after using a food dehydrator to dry it I put it in the food dehydrator for 13 hours and now I get great results.
I think I got an old batch that sat on the shelf for a little while.
Thank you for the advice Peter.
The issue is NOT that the filament is wet. Currently the way it was haphazardly wound onto the spool is preventing me from even seeing if it shows signs of being wet. It literally will not feed off the spool. Look closely at the photos, absolutely no care was taken in the way it was wound onto the spool by the manufacturer, preventing the filament from feeding properly. Look at the photos again, you will see that the filament looks like it was wound onto the spool by a 4 year old kid between their potty break and nappy time. I had the dehydrator ready to go if I had needed it, unfortunately I never got the opportunity to even try to print with it.
I love the CoPA. What I didn’t like was the price on it. Don’t get me wrong, it’s a quality product and once you get your print settings dialed in the prints are amazing. It s a good high quality product and it’s priced accordingly.
My intent with the Kodak filament was to find something similar, but with a more reasonable price. I’d love to print everything in CoPA, but at that price it’s just not possible. I really like the Polymaker filaments, but the price is pretty top shelf.
I don’t think I’ll give up on them, but for a first purchase from Kodak, I’m disappointed that a company with their reputation had an issue like this with quality control. After I dug into the reviews on Amazon for this filament, I discovered more experiences similar to the one I had. Hopefully they can get their act together because so far I haven’t seen any other manufacturer besides Polymaker and Kodak offering a PA 6/66 copolymer like this.
I also looked at the 6/66/12 filament as well, but my goal was to find a reasonably priced 6/66 blend. Material wise I really don’t see a need for me to use it at the moment. If I need that kind of performance, I’ll probably try it out.
I should have looked closer at the images of this filament on Amazon. Even there the images of the filament on the spool look like crap. Lesson learned I guess.
It may be great material, if you don’t wind great material onto the spool properly, it won’t feed off the spool Smoothly and it will get tangled up.
If you look at the following photo you can see that it has been wound onto the spool haphazardly. That is how the spool looked coming out of the bag. This is the spool that I was complaining wouldn’t feed and got dragged out of the spool holder because the filament was tangled.
I real think @jsw said it best in his post
“From your photo, it was probably respooled from larger lots, and possibly by makeshift equipment. (LOL, electric drill?)“

KODAK, does not have that much to do with this filament. Since the bankruptcy they has aggressively licensed their brand and branding to the highest bidder.
The Kodak Filament and 3D printers are actually a product by https://smartinternationalgroup.com from Argentina, they purchased a license for that market segment. Might be a an excellent filament though, don't know about that.
