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.

Très bon filament belle bobine demande d'avoir un ace pro.

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

First off I needed a rush order for a client of Black PA6-GF originally but Bambu Lab takes sometime to get so while I wait I figured I can try this out. I’m seriously impressed, not only did it adhere solid and strong to a G10 plate even with releasing adhesive. But it’s seamless on the layer adhesion and rigid AF! I love Bambu Lab PAHT-HF but it’s a pain if you don’t have perfect chamber temps and has very potent fumes. This PET-CF17 didn’t have nearly as much but still you need filtering. I downloaded their Bambu print profile and sent it! Worked first try with a 40c chamber, 75c Bed temp, 300c nozzle (Modded X1C with Panda Revo 0.4mm ObXidian) no AUX fan and printed flawless with ZERO WARPING! I don’t think I even needed a brim honestly. It’s extremely brittle! So be careful with loading and make sure to have smooth transitions in the PTFE lines. I had this loaded in the AMS as well and had zero issues! The texture on the surface finish is astounding and feels just like the competition. For only 500g’s I’m pretty happy about this product and definitely hope polymaker releases some other color options with their Fiberon Line. I wanted PA6-GF but it’s only available here in gray… I was hesitant trying this but it’s going to be a solid go-to option from now on! I think I’m going to buy the PPS-CF20 next! Trust PolyMaker they’ve been in the game long enough!!

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!

The Polymaker Fiberon PETG-RCF Filament is, without a doubt, some of the best filament I’ve ever run through a printer and I’ve used a lot of filaments over the years. I’m running a Centuri Carbon high-speed printer, and this filament handles like an absolute champ. Perfect fit & smooth feeding, flawless extrusion, no stringing, zero drama. The consistency is outstanding. Every print came out clean, accurate, and strong, without any of the stringing or weird inconsistencies you sometimes get with carbon-fiber blends. Even better: the filament wasn’t loaded with moisture. No popping, no hissing, no micro bubbles just perfect material from the very first layer. Packaging was excellent too, sealed tight, clearly cared for, and ready to go right out of the box. It’s the kind of attention to detail that makes you immediately confident in what you’re buying. I cannot recommend this filament enough. If you’re on the fence, just grab it. The performance is seriously impressive.
