R QIDI TECHNOLOGYCarbon Fiber PET Filament 1.75 1KG Spool, PET CF 3D Printer Filament 1.75mm for Most FDM 3D Printers, High Strength, Low Creep, Low Moisture Sensitivity, Black

This stuff is awesome for strong, functional, heat resistant parts. It prints amazingly well - looks better and feels stronger than even my 3DXTECH PC-CF. It never once warped on me, and doesn't seem to be sensitive to humidity like Nylon filaments. I am super impressed and will be buying more of this when it goes on sale again.

Prints beautifully! No warping and very precise. The filament is brittle so take care when loading the extruder. Tested with several shapes for strength and it's quite hard compared to plain ABS. Reduced my frow rate by 25% (24mm3 to 18mm3), 260°c nozzle, 105°c bed. Reduced extrusion rate by 1.5%. Printed on a Voron 2.4 withXOL toolhead/Hextrudort.

I think this is one of my new favorite filaments. Stuff prints so good I ordered 2 more rolls of it. I print alot of HTPA-CF and this stuff is good for parts that don't need the higher temp of HTPA-CF. The finish on the printed parts are stunning. I dried the filamanet over night @ 70c on Eibos Polyphemus filament dryer and printed direct from dryer. I use sealable ceral containers filled with color changing desicant to store after printing.Stuff printed great at 320c deg, 80c bed, 60c print chamber. I use fans speed of 20-40% and 60% for overhangs. Printed using a modified Qidi X-CF Pro with a Bondtech/slice mosquito printhead running klipper.

The bad:Last spool (not the filament) arrived cracked, making it impossible to place it on bottom rollers in my drying container. I ended up rewinding the material on a different spool (it took me almost 2 hrs), as I needed it for the project. Two times I received the filament and both times I received with damage to the spool.The good:The filament is a great combination of ABS and glass fiber. The prints come out rough or matte looking but exhibit typical fiberglass material strength. Yes, the filament itself is brittle and breaks easily if bent, which is unfortunately typical of all glass fiber filled filaments (I have the same issues with Nylon PA6 from 3DXTech). All of these fibers do best with drying out and good calibration.

Sure it won’t work in my Bambu AMS, but it’s such a good filament to print in. Incredibly strong, no smells, extremely dimensionally accurate with zero warping whatsoever. It’s completely replaced my usage of ABS or ASA. It’s a brittle filament but I haven’t had any filament breaks in my Bambu printer yet. Adheres really well to PEI and G10 build plates.

Filament is so brittle it keeps breaking even after I dried it for 12 hours plus I tried it on my QIDI printer

Seriously strong filament. Not hard to print with. Used on my Bambu Labs X1Cs without issues.

The media could not be loaded. Great Quality Filament my default Filament from the day I used it for the first time professional Engineering grade prints speak for it
