TINMORRY Carbon Fiber PETG Filament 1.75 mm, High Rigidity & Strength PETG CF 3D Printer Filament, Compatible with Most FDM 3D Printers, 1 KG 1 Spool, Black

The black petg-cf has become my favorite filament. Before I stuck to pla; petg was tempermental and needed drying so often it just wasn't worth it. I bought this to print a cable chain that required petg and I expected to suffer through it, but the stuff was marvelous. It has a gorgeous finish that hides seams and layer lines very well. And it just prints so nicely: it adheres beautifully, first layers are literally clean and beautiful, there's no stringing, there's no lumps or wads or tangles sticking to the print, I can print faster than I expected (50 for 1st layer, 120 after that on a rickety Elegoo Neptune 4 Plus) and the stuff is *strong*. It's not as flexible as regular petg (a good thing) but still snaps together nicely. I printed the chain, then a circular knitting machine, an enclosure to keep the cats off the printer, storage boxes, and on and on. I'm on my sixth kilo of this stuff and it's still awesome. Well, well worth the price.

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’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.

Filament kam wie bei Amazon üblich schnell und gut verpackt an, im Paket befindet sich noch ein Beutel für die spätere Verpackung. Auf der Spule finden sich Infos zu den Druckparametern und dem Leergewicht. Habe das Filament getrocknet, kalibriert und nach einem Mix aus Voreinstellungen von Bambu und den Herstellerangaben verarbeitet. Druck lief gut, Modell wirkt sehr stabil, allerdings bin ich mit der Oberfläche noch nicht ganz zufrieden, hier muss ich nochmal ran.

Filament Tinkorry PETG-CF Brick Red Als erstes muss ich sagen, TOP Filament !!! Filament durchmesser fast immer 1,75mm dick. Ich habe einen Bambu Lab P1S mit einem Highflow E3D Hotend mit nur einen Düsendurchmesser von 0,4mm. Filament vor den drücken getrocknet. Temperatur ergab 260 grad Celsius. Der Hersteller schreibt auch vor 240-270 grad Celsius. Betttemperatur 70 grad. Ich habe die Maximale Flowrate ermitteln wollen habe aber bei 40mm3/s abgebrochen da dies für mich schon das Doppelte von meiner geschwindigkeit erreicht hat. Vollkommen ausreichend, manche Carbon Filamente schaffen keine 20mm3/s. Layerhaftung sehr gut. Kein Warping gehabt. Kein Stringing. 👍👍👍👍👍 Filament Tinkorry PETG-CF Brick Red First of all I have to say, TOP filament!!! Filament diameter is almost always 1.75mm thick. I have a Bambu Lab P1S with a highflow E3D hotend with only a nozzle diameter of 0.4mm. Filament dried before printing. Temperature was 260 degrees Celsius. The manufacturer also specifies 240-270 degrees Celsius. Bed temperature 70 degrees. I wanted to determine the maximum flow rate but stopped at 40mm3/s because for me this was already twice my speed. Completely sufficient, some carbon filaments cannot achieve 20mm3/s. Layer adhesion very good. There was no warping. No stringing.

Polecam :)

Zaskakująco łatwa kalibracja, wytrzymałość i wygląd po wydrukowaniu. Polecam.

La calidad del filamento es insuperable. llevo tiempo usando filamentos de esta marca y cada dia me gustan mas. Los acabados son sencillamente perfectos. Ajustando los parametros como toca, ningún inconveniente. Sin duda un filamento muy muy Top
