I printed the Watering Sprinkler STL from the page above in PC-ABS and it came out great! Easy to print in an enclosed printer with a great surface finish. Perfect for functional prints where you know it needs to be strong or stand up to the elements.

Not the first time I’ve used Sunlu with great results and likely not the last. I printed a new extruder housing for my Elegoo Centauri Carbon, decided on this filament as I need durability and heat resistance since it’s near the hotend. I then printed an additional hook for my utility shed to hang tools. It won’t be expused to UV but extreme heat in the South Texas summers

SUNLU PA6-CF has become my go-to engineering filament. I’ve tried several carbon fiber nylon filaments, and this is the only one I fully trust for functional, high-strength parts. It prints consistently, has excellent layer adhesion, and produces strong, rigid parts with a great surface finish when properly dried. I’ve used it for demanding projects where strength and durability matter, and it has never let me down. If you’re looking for a reliable engineering-grade filament, I highly recommend SUNLU PA6-CF.

I ordered one of these rolls same day shipping to print some car part brackets that were going to take several weeks to ship. 3 hours later is was printing and installing in vehicle! This filament printed great with no breaks or issues and has been a lifesaver. Seems very durable far and it is something I would highly recommend to others!!! (White was a similar original part from another area. Black item is the item I needed and printed.)

Printed a few things so far with this filament and so far for my first carbon fiber filament it’s been pretty easy to work with! I love how easy this was to actually print and I didn’t have any buildplate adhesion issues at all! Highly recommend if you want to try some carbon fiber filaments! Color looks good and no layer lines at all. Zero clogging issues after over 200g of filament used! Quality is great for the price! Highly recommend!

This PA6-CF is the bomb, cheap and very strong. Not super strong but thats not what Im here for, I say not super strong but you can't shake a stick at it. This stuff is exceedingly effective. I will buy a lot more continuing on.

Dried for 12 hours in my E2 dryer. Only one issue is the filament was held onto the spool with tape. That tapes adhesive couldn't hold on at the 80C drying temp. It ended up unspooling a little. I'd recommend feeding it through the spools holes before drying. Using only a slightly modified profile for Bambu PA6 profile I printed a few things and am amazed how well it turned out. Printed @260C, Chamber temp 50C. Came out pretty smooth. Pics look rough but it's smoother than it looks. Layer adhesion was great. I also annealed the parts in my E2. Now I'm excited about printing some of my bigger projects. This is my favorite PA12 I've printed with so far.

VERY easy to print with. My print is strong yet flexible. Less prone to moisture absorption than PA6. It is a very rich black that looks the same extruded as it does on the spool. The layer lines bond extremely well and the finished print resists breaking apart and retains flexibility that will allow this filament to be used as a spacer, bracket or hinge in functional parts that require durability and strength. I highly recommend this filament.

Makes very nice looking, sturdy parts, with a matte finish. However, I had to turn the extrusion down to 80% to get clean parts (not over-extruded looking, sharp edges). I've attached some microscope images of an example part where you can see that there's some porosity in the printed material. I don't know why, since there's been no obvious signs of moisture (no popping, hissing, etc.). My filament drier doesn't get nearly hot enough to dry this filament properly, so I can't say if that would make a difference. Filament diameter was around 1.75mm, as expected. I've had zero issues with clogging, tangling, bed adhesion, or warping (even on very long, thin parts), and there isn't an obvious smell, so this might be my new favorite filament to print with.

Strong and durable, spool was dry when I opened the package. Doesn’t print quite as fast as fiberon but at half the price a few extra minutes of print time is worth the savings. Overhang printing was great. Photo: This is a AI designed wheel for an ice chest dolly for use on loose sand at the beach. Despite the relatively thin spokes it has proven very strong. Wheel weighs about 300g and is designed for a 60lb cooler, with 2 of these wheels there is a nearly 10x safety factor(600lb). No supports needed for the spokes.

printed some sprockets on an H2C for a chain drive transmission, they turned out great and are super strong. i plan to also print motor plates using this filament that the designer recommends using aluminum and i have no doubt it will work great.

Very easy to print and durable! With the way the texture of the material is not silky smooth like PLA, but rough and gritty feeling like sand, I thought I would test the limits and make a print in place nesting retractable self defense baton. It came out perfect and nothing fused together! Very impressed!

Great filament! Incredible first layers. Great bed adhesion and release. Works phenomenal on my Qidi Max4 with the Qidi Box MMU. Nozzle temperature: 280-320°C Bed temperature: 80°C Print speed: 20-80 mm/s Cooling fan: 20% Retraction distance: 0.8-1.2 mm at 40-60 mm/s Flow rate: 95-105% Layer height: 0.2-0.3 mm I used .24 Infill: 10-40% Supports: Standard tree or normal supports Nozzle: Hardened steel required Enclosure: Ran well with the cover off. These settings delivered consistent, strong parts with incredible interlayer adhesion once the filament is properly dried. We botched the design on a part so we broke it as a destructive test. This Sunlu EasyPA bends before it breaks, almost like wire.

This ABS-GF prints beautifully and easy. The filament came in a vacuum packed sealed bag and no issues with packaging, filament was neatly wound and no tangles. Zero clogging or printing issues at 280c, adhesion was great, no warping. The GF adds additional strength interweaving through the ABS, also helping with even cooling. I love how the glass fibers eliminate any layer lines and gives the ABS the matte appearance with little specks in the finish. You couldnt tell this storage tray was 3D printed, its that good. I highly recommend this brand and filament!

Wow!! This stuff is very durable. I was making floating center caps using regular abs and it was wonderful but bends too easy. I redid it with this filament and it’s way more stout. I did try to print right out of the bag but it definitely needed drying. Once dried and calibrated the material print flawlessly. Sunlu has been my go to for small toys to big moving parts.
