  • $ 4999



 Available in ONE KILO (2.2lbs) & 3.5 KG Jumbo rolls

  Also Available in 3.5KG Jumbo Rolls - CLICK HERE


Prints with a deep black slightly textured surface & no transparency.

Filament and parts are NOT brittle like some other CF products. Excellent for professional looking technical prints.

Engineering grade PETG resin with USA made premium MILLED carbon fiber NOT powder or dust.

PETG is a newer printing filament and has the advantage of printing easily like PLA, but offering higher temp and impact resistance like ABS.


Carbon fiber infused filament benefits:

  • Increased rigidity / strength
  • Highly desirable texture / look
  • Greatly reduced part shrink / warp
  • Greatly reduced stringing / angel hairs
  • Printed parts hold better details / sharp corners

Get Ready to Raise the Bar!

I am just wrapping up a net new Prusa MK3S+ build with a Bear 2.1 frame. I'm printing the Bear plastic parts using the stock Prusa .20 "Quality" Slic3r profile at 250C on a Buildtak PEI sheet at 75C. The only modifications I have made to Prusa's stock profile are the part-by-part variations in perimeters that the Bear print settings require. Unlike my early experiences with a different vendor's high-end matte finish PETG filament, these prints stick and release as they should from PEI (with Windex applied before starting each print) and the finish is consistent and really nice with little to no stringing at all. I have never had such an easy time printing PETG before and I think my prints are just beautiful - even if they are just functional parts for a printer or CNC machine. I just received two more rolls of Atomic PETG-CF in today's mail, and I can't wait to see how my MPCNC build comes out using dark blue/ultra black. If you are at all on the fence, don't be - this stuff is really that good and well worth the price especially if you factor in that you likely won't have any waste due to failed prints or endless calibration. And speaking of being "that good" - this was ordered very early on Friday morning and came in Monday's mail, so it's clear that Atomic is firing on all cylinders when it comes to both product and service. If there's any downside at all, it's simply that you may find yourself reprinting perfectly functional parts over again just because you want to see how much better they will look when printed with Atomic CF. But that's a risk worth taking. ;-)

Thomas, I don’t think my mom would be that nice! Thanks for the amazing review.

Outstanding Product

I'd expect a fiber filled product to present difficulties. However, I found this material as easy to print as unloaded PETG. The print parameters I used for PETG worked just as well with less stringing. As many people noted, the texture hides the print lines. The carbon fiber gives a matte texture which looks less plastic. It's all the good things with PETG combined with improved strength. Except for installing a steel nozzle, a novice can use this with no issues.

Gary, glad to hear the ease of use. Excellent to hear!

Am enjoying this filament

I was using a different filament for an ongoing project, and I was becoming less satisfied with it. I have started using this CF filament and am liking how things are turning out. It is about $15 more per roll than what I was using, but the quality of my finished piece has been great.

Atomic Filament

Yes Lyle, we are not inexpensive. And I am so glad the quality matters and you can see it! We really work hard to make the best!

Awesome stuff

I grabbed a roll of this CF PETG to print a couple of parts I needed to be more rigid compared to regular PETG. This filament is much stiffer than regular PETG and as a bonus it prints easier. Way less stringing and very nice surface finish. The only adjustment I had to make from my regular Atomic Filament PETG profile was to increase the nozzle temp. Yes, I *increased* the temp and have way less stringing with a PETG based filament! Definitely a recommended filament if you need/want PETG characteristics but want/need less bend in the printed parts.

Patrick, great comment. Thanks for the info for the rest of our community!

Best quality prints I have ever done. Best balance of print quality and strength. Carbon fiber obscures layer lines and makes for a great looking print. Bought more immediately. I also bought blue cf petg and I am waiting for red cf petg to come back in stock.

Matt, Thanks for the fantastic review. We live on this sort of feedback! Will be on that Red CF soon...
