Color: 114 - Polymide Pa6-gf 1.75mm Grey 0.5kg ...
Size: NYLON
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.

Color: 111 - Fiberon Petg-rcf08 1.75mm Black 0....
Size: PETG
This stuff prints like a dream on my Bambu Labs A1 with AMS Lite. It looks absolutely fantastic. I did dry this filament for about 6hrs at 50°C just in case it was damp from the factory. It might have been perfectly dry when I received it, but I wanted to give it the best chance, so I dried it anyways. This filament is supposed to have less stringing than regular PETG, and that was what I found to be true. I had no stringing whatsoever. As I said earlier though, I did dry the filament prior to using it. This filament is not recommended to be used on the Bambu Labs AMS Lite due to it being slightly abrasive and the filament is more brittle than regular PETG or PLA (you can easily snap the filament with your fingers), but I tried it and had no issues with filament breakage in the AMS Lite, even with multicolor prints. I ran both Bambu Lab config tests and decided to up the K-factor to 0.05 and leave the flow rate at the default for the "Generic PETG-CF" profile that comes with Bambu Studio (which is 0.95 flow rate). I printed multiple models on the Textured PEI plate, 70°C bed temp, 260-265°C hotend, and all of it was perfect right off the bed. I did slow the print speeds down to 200mm/s for walls/infill and 70mm/s for over hangs. 5%-40% max part cooling fan. I did not have any clogs or issues feeding the filament through the standard 0.4mm hardened steel nozzle. Don't use the regular stainless steel 0.4mm nozzle; the filament it too abrasive and will widen the nozzle slowly over time.

Color: 111 - Fiberon Pps-cf10 1.75mm Black 0.5k...
Size: PPS
If you have a suitable, enclosed 3D printer, with a very high temperature Hotend.... Fiberon PPS-CF10 is the greatest! It prints well with no unmanageable warping and prints come out with good precision of dimensions provided it is dry. Parts are strong, stiff, stable, extremely temperature resistant and non-flammable.... this just refuses to burn, even when held in a propane torch, it just melts. It does need to be dry but is fairly easy to dry in an oven set to 100C. Expensive? Not really for a high-grade Engineering material. My new go-to.

Size: NYLON
Amazing project. Just make sure your printer can handle the temperature requirements and has a hardened nozzle. A heated chamber can’t hurt either, but isn’t 100% necessary. Prints come out flawlessly - vertical surfaces are smooth and you can barely see the layers. The prints come out extremely strong and durable. Stringing can be a bit of an issue, but adjusting your settings accordingly will do away with most of that. Great price for an event better product.
