Polymaker Fiberon PA612-CF15 Carbon Fiber Nylon Filament 1.75mm Black 0.5kg, Fiberon PA612-CF15 Strong & Low Moisture Sensitive Nylon 1.75mm 3D Printing Filament

I printed the above image with a stock Kobra Max (260° max nozzle temperature. Although some people suggest it runs hot), 0.8mm nozzle(not a nozzle suggested for small gears)... I have been printing for a well over 5 years and it's not just a side hobby. It's not work but it's an obsession. I've had many printers, I've tried innumerable brands and types of filaments. This is my first favorite. I'm going to write a simple list of why you should buy this filament. By far the strongest filament I have ever used. It's a different kind of strength though. PC FG/cf, peek etc might be stronger in certain ways, But having the same volume as a regular kilogram, yet half the weight, it's just something special. Just a note, the way this filament works is a lot like say porcelain. It's an incredibly strong substance, but if you kind of chip away at it with say a pair of bolt cutters, it'll break easier with scary pieces flying at you.. Kinda like that. Dimensional accuracy is off the charts. You make a hole, the whole will be the size you make it. I only have one printer that prints perfect every time. A toybox printer.. If you know what that is, you'll understand. Anyway, this filament in my Kobra Max, is officially my new most consistent and reliable print. I use Cura to do the "print one at a time" (instead of all at once), and I can have 19 different prints I want done all in that one platform, and it'll just go through one after the other and print them all completely accurate. No more checking every 30 minutes or hour. No need for a camera mounted on it or special failed print sensor... Keep the support material as low density as you can, but when it comes to the support interface and removing this support, it's amazing. The support interface ACTUALLY works...... Really. And once you break off the support which CAN require a lot of strength (ice pick or smaller nozzle size suggested) You're left with a manufacturer quality part. No post-processing necessary. A real quick note, I tried doing the flow reduction for the support material and it ended up failing. I'm sure it's because this material is very thick/.8 nozzle/and printed well below the suggested print temp, But that did fail me. Anyway, I'm sure if you actually have the appropriate setup/settings you'll be fine. Print your support flow to give you ~0.2 mm support line width. Then it should break off super easy, clean and without any excessive strength. Guess that's really all I have to say. Aside from the fact that it also has a really nice texture. Oh, and make sure you use "alternate wall printing direction" or something like that. I'm sure even if you use a smaller nozzle size, there will be a little pull like with metal field or glass filled filaments. You want to make sure it changes direction each layer to avoid that warp and shit. If you use Cura, the newest update has that option in experimental or somewhere at the bottom. This is my summary. I'm using a stock printer, oversized nozzle, and very little is done to try and accommodate this filament suggested print settings. I'm honestly not even sure how it works. But regardless, I'm getting manufacture quality parts. Truly functional. I have every other filament. And although some might have higher strength in certain areas(and usually some disadvantages), but they all require some specialty equipment, tons of work to get it to stick or print clean. High build plate temperatures that waste electricity and often result in warping. And so on and on. And maybe ridiculous for me to say, but I think this is the best filament ever produced...(Aside from basic PLA for prototyping). I just want to know if it comes in 5 kg.

Printed a benchy within a few hours of receiving my spool. I printed directly from my dryer, but didn't wait for it to dry out after loading - call it a factory packaging check. The little boat came out nearly perfect. The only thing I've noticed is that the open-air extrusion is kind of wavy, like the fibers aren't happy about going through my 0.4mm nozzle. I bet a 0.6mm would alleviate this completely. As it stands with the 0.4mm, there is some light waving that makes it into the print but not much. I saw no stringing at all, and the overhangs look fantastic. Surface finish has a unique sheen to it and is *extremely* rough due to the carbon fibers sticking out of it, if I was printing something that will be handled a lot I'd want to put a few coats of clear paint over it first. Flicking the benchy with my fingernail it sounds kind of glassy, suggesting that the part is as stiff as it feels. I like to break the chimney off of benchys to check layer adhesion and this stuff hurt my thumb and took a couple of tries. I bet with annealing and conditioning it would have hurt my thumb even more. Great filament, will reorder when I need it again.

Good and strong filament. Print well

Very nice filament. Comes decently dry out of the box and prints very well. I use the bambu preset for it and I haven't had to do any tinkering with the settings, the surface is beautiful and the print is very solid. Its a little expensive but its tempting to switch over to this for everything. Using glue on the bed i have never had problems with adhesion like I have with abs or asa

I'm printing a cold air intake system for my car from this stuff. 4mm think walls on 2 1/2" tubes are as strong as I could buy in anything below aluminum. And the temp resistance is high enough that it's only ever going to be an issue if my car catches fire. Good stuff, highly recommended.

Excellent product, probably the best cf nylon you can get especially for the money. Prints with virtually no layer lines. Comes out a matte finish with a little texture which is to be expected. Tough tough tough! Amazing because it feels so light but it is deceivingly strong for how light it is. The only issue with it is warping and bed adhesion. Print with a large brim if what you are printing has a small footprint and you should be fine. I wouldn't even try without a heated bed and enclosed environment though. 280c seems to be hot enough for me.

Easy to start printing with and had quality bed adhesion, maybe too much bed adhesion. The only issue I’m having is on me and that is it quickly clogged the printer’s nozzle. I suggest purging the filament before it cools if you’re using a high flow nozzle. It came tightly wound and fairly dry making setting up printing take a short time.

This is impressive stuff. I am designing motorized equatorial telescope mounts and needed a material that is rock solid for some of the parts. After much consideration I settled on the PA612-CF and it has performed well. I am using an A1mini with a glass bed and glue stick. With a little trial and error, I got my temps set. Then a flow calibration dialed in perfect prints. I actually have to use a metal scraper to get the prints to release. To get more out of this filament I anneal everything at 90°C for at least 6 hours. To compensate for shrinkage, since I am printing precision parts, I increase X and Y axes to 100.10% and Z axis to 100.50%.

Liefert sehr gute Ergebnisse, robust mit einer schönen Oberfläche. Allerdings ist hier ein gewisser Aufwand erforderlich, die hohen Temperaturen müssen genau eingehalten werden und die Trocknung muss regelmäßig erfolgen. Am besten ist es, aus einer beheizten Trockenbox zu drucken.

Stampato perfettamente con Qidi Plus 4.

Très bon filament belle bobine demande d'avoir un ace pro.

ottimo. mi sono trovato subito bene. resistenza impressionante

Prints really well. Needs lots of drying, but well worth it. High quality parts produced.
