PETG-CF Carbon Fiber PETG Filament 1.75mm, 1 KG, Black | Carbon Fiber Reinforced, High Rigidity & Strength, Low Warping, Strong Z-Adhesion, High-Speed Printing, Wide Compatibility

After testing several PETG-CF options, this filament has become my go-to. It prints smoothly, adheres well to the bed, and offers a great balance of strength and flexibility. One of the biggest positives is how easily supports break away, making post-processing much simpler compared to other carbon fiber PETG filaments. Print Quality & Ease of Use From the first print, it was clear this filament was well-formulated and easy to work with. It flows consistently, doesn’t clog, and produces sharp, detailed prints with minimal stringing. The smooth extrusion results in clean, well-defined layers, and I’ve had zero issues with stringing or blobs, even on complex prints. The matte finish gives parts a professional look while also reducing visible layer lines. Great Compatibility with Bambu Printers I’ve been running this filament on my Bambu X1 Carbon and P1P, and it’s been incredibly reliable. It feeds smoothly in the AMS, maintains excellent dimensional accuracy, and doesn’t require constant tweaking to get good results. Moisture resistance also seems better than other PETG-CF options, making it more forgiving over time. Positive Pre-Sales & Product Support While I haven’t needed support for any issues, I did reach out with pre-sales and general product questions, and the response was quick, helpful, and knowledgeable. It’s clear the company stands behind its product and is engaged with its customers. Final Thoughts This filament has earned a permanent spot in my setup. It’s smooth, reliable, and easy to work with, delivering strong, high-quality results without the usual frustrations of PETG-CF. No stringing, no clogs—just great prints every time. If you’re looking for a dependable PETG-CF filament that works seamlessly with Bambu printers, this is an excellent choice.

I can't praise Tinmorry PETG-CF filament highly enough. It is easy to calibrate, easy to print, and allows me to produce highly durable functional parts with precise dimensions and beautiful matte finish. With it, I have never encountered any warping, stringing or delamination -- it is very tolerant to both printing and bed temperatures and fan settings, which can deviate from "perfect" but still yield a good result. I don't remember a single failed print, even when I accidentally used wrong settings (though, of course, the best results are obtained when all settings are correct). Clogging is also a non-issue, even with a 0.4 mm nozzle. With this material I can even print springs: it is rigid, but can flex and, more importantly, return to its original shape once the force is removed. For all it its great mechanical and aesthetic qualities, it is also quite inexpensive -- especially compared to the likes of PA-CF, which can easily cost twice as much, but are not as easy to print with. Now, some downsides, or rather "considerations". When printing with PETG-CF (or any carbon fiber containing filament), it is important to make sure you printer is equipped with _both_ a hardened nozzle and a hardened extruder gear set, as it is quite abrasive and can ruin your "regular" steel parts in no time. (For my Bamboo Lab P1S such upgrade cost me about $40). Sanding this material is usually a bad idea unless you're doing it outside and wearing a respirator mask, because the dust particles it produces are irritating, not biodegradable, and thus very harmful to inhale. (Good thing you don't need to do it often because the finish is usually great as is). I'd also like to mention that this plastic is not fully radio-transparent because of CF content; so it is not well suited for making enclosures for electronic devices containing a functional radio antenna. Overall, it is a very reliable material yielding highly consistent results, and is now one of my favorites. 10/22/24 update: recently I had a chance to compare it against very premium and four times more expensive Qidi PA12-CF filament. I have to say that, while the latter definitely has some advantages (such as scratch and heat resistance), Tinmorry PETG-CF still holds better in terms of dimensional stability, rigidity, color and overall finish. It will remain my "to-go" material for most projects, while PA-CF will be used for printing gears -- the only application I can currently think of where its advantages are crucial. P.S. I'm adding pictures of my Kiwi-drive ball balancing robot, with 95% of its structural parts printed from Tinmorry PETG-CF. It already took quite a lot of beating (inevitable when you have a five-year-old in the house) but still looks almost like new. And if any part eventually breaks, I can easily print it again.

Printed some awesome stuff with this filament. It's insanely easy to print, compared to bambu labs petg cf this stuff printed faster and had way better layer adhesion than the bambu stuff. It also for whatever reason didn't suffer from heat creep at all. I like to heat the chamber to around 50-55c to help with better layer adhesions and it has a more even surface finish. I don't recommend a heated chamber for most as I know heat creep is a problem but I have not had any issues. I don't recommend CF filaments for anything you touch a lot as they do release small fibers which have little research on long term exposure effects. This stuff is great for functional parts. I've printed button boxes for motion racing sims. Printed a vent holder for my portable ac that is hot swappable and a external grill. The air going through the grill is at around 140f and there is no warping after 2 months. I also made a reverse light mount for a side by side and it has seen itense terrain and has been beat on a ton and is still holding up fine. Definitely need to dry this before use but so long as you dry it good I have had 0 complaints!

I’m currently on my second roll of Tinmorry PETG-CF filament with my Bambulabs P1S, and it has been a fantastic experience so far. I've tried other PETG-CF brands, but this one stands out as the best. Every print has been flawless—no stringing, excellent overhangs up to 40 degrees, and significantly improved bridging. The parts come out with a sleek matte finish that effectively hides the layer lines, making it difficult for most people to tell that the part is 3D printed, even if they’re familiar with printed pieces. I primarily print functional parts, and for that, PLA just doesn’t cut it. PETG has the right amount of flexibility, but it does come with some downsides. Adding carbon fiber solves most of those issues, providing extra stiffness. In my testing, this PETG-CF lasts about twice as long as regular PETG and holds up 10 times better than standard PLA. A client unintentionally left test parts made from PLA, PETG-HF, and this PETG-CF in the front seat of his car for a week in 90°F weather. The PLA became a distorted mess, the PETG-HF from Bambu shrank more than expected, but the Tinmorry PETG-CF remained perfect. It's also far more dimensionally stable than any other filament I’ve used. I used the standard PETG-CF profile in Bambustudio, and although I dried the filament beforehand, I didn’t bother with any additional calibration. Even so, the prints came out flawlessly, with most dimensions holding within 0.05mm. I’m using the recommended hardened 0.4mm nozzle and extruder on my P1S, along with Aquanet hairspray on the textured bed, as the adhesion is so strong that I’ve ruined glass beds with PETG in the past.

I’ve been using the TINMORRY Carbon Fiber PETG filament on my Bambu Lab X1C, and the results are impressive. The filament prints beautifully with excellent layer adhesion and minimal warping. The carbon fiber blend adds noticeable stiffness and strength, making it perfect for functional parts that need durability without sacrificing detail. Surface finish is matte and professional-looking, which is a nice bonus for aesthetic projects. It runs smoothly through the extruder with no clogging issues, and dimensional accuracy has been consistent across multiple prints. Drying the filament before use helps achieve the best results, as with most PETG CF blends. The only minor downside is that it’s slightly more abrasive, so a hardened steel nozzle is a must. Once set up properly, this filament delivers strong, lightweight parts that feel premium. Highly recommended for makers who need strength and style in their prints

Tinmorry makes good filament, this one prints very well and with the appropriate settings is very strong. I’ve printed several parts that are in stress-bearing applications and they have held up well with no wear or breakage so far. CF will wear your nozzle, so make you use hardened steel. Even then I’ve had to replace them after about printing 3/4 of a roll or so and going back to PLA or PETG. Highly recommended!

Super easy to print PETG, no issues with clogging, tangling, or anything else with it. Another review had some settings for a KS1, and those worked perfect for mine. No issues with stringing, and have fantastic layer adhesion and first layer adhesion. Have not had any issues with prints breaking. Easily the best PETG I've used, and the price is very good for the quality.

I'm putting a review here as well as a little info for those who do not own a k1C or something such as a bambu labs x1-carbon. I am using a creality labs K1 Max with the unicorn nozzle and upgraded metal extruder wheels/gears. I literally used the default PETG setting in orcaslicer and simply slowed the print down on my K1 Max to 50% to be safe. I've read you can go at 75% but have yet to try. My max has the unicorn nozzle so it is not reinforced to my knowledge. However, nozzles aren't too expensive so it's not a problem while I wait for an upgrade. For those not using a unicorn, I say to get a ruby tipped nozzle of better. Then I would suggest metal extruder gear upgrades. This combo should have you ready for most abrasive filaments. I plan to use my V400 as well and test that. So far this filament is awesome. It looks amazing, layer lines are so crisp and smooth, ease of use out the box was surprisingly simple, the box comes with a simple plastic bag to help keep dry in between uses and this material is rather inexpensive compared to even some simple PLAs on the market. With the low costs and relatively simple use, I expect to get more of these for certain in the future. Also, the carbon fiber petg comes in several different colors as well which is awesome! This may become my replacement for pla and petg in a lot of my personal projects. I fully recommend!

No tuve que mover ningún parámetro de la impresora, simplemente use el perfil para PETG estándar y funcionó a la perfección. El color y acabado realmente es impresionante, en algunos ángulos incluso desaparecieron las lineas de capa, definitivamente lo pondré en mis filamentos de uso diario.
