I dove head first into 3d printing with a hammy down Ender 5 pro, my first project was a diesel heater in a pelican case and this petg-rcf08 filament. I was struggling given I’m pushing my novice knowledge and this machine beyond its stock capabilities and wound up melting my Capricorn tubing in the stock hot end resulting in extreme amounts of stringing and lack of fusion between layers. however after stepping away and trying to figure out everything with pla and coming back I’ve figured it out my plan of attack little better. I ran max heat 260c that my machine was limited to and bumped up the bed temp to 70c. Now I’ve gotten results I’m happy with! Im still getting a bit of stringing but I think with a little more retraction and heat I’ll be right where I’d like to be! Make sure to use something like purple glue sticks to limit the bed adhesion because this stuff will weld it’s self right to the bed surface, right now I’m putting together a mercury v1 kit to run my Ender machine at the recommended 270c and I’m using this material for the parts and I’m very pleased with my results given my limitations at the moment. The texture of the material hides layer lines well giving off a nice sleek satin black, also the strength and heat resistance is impressive! for a beginner it was a bit of a challenge at first knowing nothing about 3d printing but honestly overall it’s a pretty forgiving filament for the price I wouldn’t think twice about using it again!

Prints look great with this filament. It hides layer lines well. Nice soft texture to prints. Prints easily, even my open-air printer. Makes very strong functional prints. Adhesion is good with layers, but can be brittle with smaller parts. Handles higher heat applications well. I did some parts for a diesel heater And they are both strong show zero signs of warping. It’s a shame the price is so high. I’d just se this as my go-to filament if it wasn’t so expensive! Read more

Sehr gutes Material. Ließ sich auf dem X1C mit den dafür vorhandenen Einstellungen sehr unkompliziert drucken. Brauchte für einen Trockenmittelbehälter die hohe Temperaturbeständigkeit, werde das Filament aber jetzt auch für andere Teile verwenden. Read more

perfect quality. it came dry (only 12% humidity), it prints really easy, just almost like pla. no warping, no bed adhesion problems at all. It is not like any other PA I tried to use before. Read more

Absolut einfach zu drucken und tolles Oberflächenfinish. Einziges Manko ist, dass es nur grau gibt. Read more

Piezas acabadas muy resistentes, no es nada flexible, asegúrate de que tu impresora pueda manejar arriba de 280 grados, y una boquilla adecuada para filamentos abrasivos, la alimentación a la impresora no puede tener curvas estrechas por qué se fractura en ellas, en la Creality k1c tuve que alimentarlo desde arriba, con un trozo de tubo, y no usar la alimentación de la impresora, puse un trozo de filamento para que el detector no pausara la impresora, al usarlo debe estar seco, seco, y más seco. Lo usé para unas piezas de una herramienta que estamos fabricando y quedaron muy bien. Read more

I recently started using PA612-CF15 filament in my 3D printer, and it's been an excellent material for high-performance, industrial-grade prints. Here's my detailed review: Print Quality & Ease of Use: The PA612-CF15 filament is a 3D printing material that combines polyamide (nylon) with carbon fiber. It’s a bit more challenging to print with compared to standard filaments like PLA, but it produces outstanding results. The carbon fiber reinforcement provides extra rigidity and strength, and the printed parts come out with a nice matte finish. I’ve found that it’s crucial to adjust the print settings for optimal results—slower print speeds, higher temperatures, and a hardened steel nozzle are key to getting the best quality. Strength & Durability: This filament’s main selling point is its strength. It offers excellent mechanical properties, including high tensile strength and low moisture absorption, which means printed parts stay tough and won’t warp or weaken easily. I’ve used it to print functional parts that need to withstand a bit of wear and tear—things like brackets and connectors—and they’ve held up impressively well. The carbon fiber content also adds to the durability, making it ideal for parts that will be exposed to high stress. Printing Performance: While the PA612-CF15 filament prints relatively well, it’s a bit finicky when it comes to adhesion. I highly recommend using a heated bed, as well as a build surface that’s designed for high-performance filaments (like PEI). Once you’ve dialed in the settings, however, it adheres well and delivers smooth, strong prints. Post-Processing: Another benefit of this filament is its ease of post-processing. You can sand, drill, or machine it with minimal effort, which makes it ideal for parts that need to be further customized. However, because of the carbon fiber content, it can cause additional wear on your print head, so you’ll want to use a hardened nozzle to avoid clogging or damage. Finish & Aesthetics: The carbon fiber content gives the prints a unique, matte black finish that looks both sleek and industrial. This is great if you’re looking for a functional yet stylish end product. The finish is slightly rough to the touch, which adds to the overall durability and strength, but it’s also one of those materials that looks even better the more you use it. Overall: PA612-CF15 filament is a fantastic choice for anyone needing durable, strong, and heat-resistant 3D prints. It’s best suited for functional prototypes, automotive parts, or anything that requires robust mechanical properties. While it takes a little effort to get the settings just right, the results are definitely worth it for demanding applications. Rating: 4.7/5 Pros: High strength, excellent durability, easy post-processing, great finish Cons: Requires careful calibration, can cause wear on nozzles, difficult to print with for beginners Read more

This might as well be as strong as aluminum. Prints just as easy as PLA on the right machine if properly dried, no weird warping issues although it does shrink and expand a tiny bit depending on moisture so account for that. On the TDS it says that annealing and water conditioning is important to achieve max strength. I annealed my prints at 100c inside the oven for 10 hours and then left them in a tupperwear with a wet sponge for two days after. The result is some extremely tough parts they almost feel like sintered nylon. Read more

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