3DX Carbon Fiber Reinforced PETG Filament 500g (1.75mm) - Black - 0.5kg - 1.1023lbs

Excellent, excellent material. Great printability, minimal stringing, good layer adhesion, amazing carbon finish. High CF content. Much stiffer than normal PETG. Likes to be printed hot (250-255C) and slow (30-35 mm/s) with no fan. Sticks very well to the Creality magnetic bed at 80C. Hardened nozzle is a must. When they say it's abrasive, they're not kidding: a roll of this stuff ground the sharp tip or my MicroSwiss supposedly wear resistant plated brass nozzle flat, losing 0.3mm in overall length (Turn off combing in your slicer to avoid dragging the nozzle over the surface. This is a nozzle killer.) I since switched to a tungsten carbide nozzle and stainless steel extruder gear for a good measure, as the brass one was starting to show wear. Made in USA!

DO NOT EXPECT THIS TO DO EVERYTHING! Carbon Fiber does not necessarily mean more better! Benefits are added rigidity, slightly better heat tolerance and abrasion resistance. Plus it looks cool MOST STANDARD PETG WILL BE STRONGER AS FAR AS SHOCK RESISTANCE AND INTER LAYER BONDING That being said, 3DXTECH did an outstanding job with this filament and any reviews you see negative are more than likely due to people who dont know what they're doing. This printed first shot out of a Hermera Revo 0.6 (dont recomend 0.4) with no tuning and has never given me a problems. Its my go to if i need an easy to print rigid material!

This stuff is very easy to print with. The filament itself is brittle due to the carbon fiber so make sure it doesn’t bend towards 180 degrees. Part finish is very nice. I attached a picture of a few small pieces I printed.

Thus far I have gone thru 3 spools and have found the filiment is fairly reliable (good and bad). Im printing on a Prusa MK3S with a Steel E3D Nozzle X - V6-3mm x 0.50mm and PEI bed. My temps are 285/290 nozzle and 85/90 bed temps and a .3 layer height (standard prusa PETG filament settings except for layer height) My only printing complaint is bridging, it sucks big time. Ive tried a lot of different bridge settings and thus far ended up having to remove the first bridge layer if its over 10mm. The good news is that for my first three parts there is only one large bridge area which is not critical to look or strength of part. Ive included a current part printed with CarbonX PETG-CF.

Great adhesion, clogged once with .4 nozzle but I was running a lower temp and my dryer was off but after that things were great! Beautiful filament will be buying more from this company. Oh and the spools are super nice too
