Write a review

PLEASE NOTE: Sadly, we've stopped supplying filaments. After much consideration we've chosen to recommend the following supplier as an alternative.

Here's why:

  • Excellent dedication to customer service, quality & range of materials.
  • Very competitive pricing & UK based.
  • High reward customer loyalty plan.
  • FREE UK delivery on all orders.


What is Carbonyte?

Carbonyte is a Carbon Nylon blended filament.

Carbon fibre is a seriously strong and low density material, it’s only done justice in a composite with a copolymer that has qualities to perfectly compliment carbon. While carbon is stiff and light, Nylon 12’s properties are that it’s the most durable (and in our eyes, generally superior) 3d printing material available.

Combined with it’s low friction coefficient, low density and high resistance to heat and chemicals – Nylon 12 was the perfect accompaniment to create this performance filament.

The addition of the carbon fibre material has also granted this material improved UV resistance over standard nylon materials.

The result?

An uncompromised blend of Carbon Nylon (or PA-CF for short) that knows no competition. This blend offers the outright highest strength of any FDM printing filament we’re currently aware of (please let us know if you find stronger). While boasting incredible stiffness combined with a reassuring level of subtle durability and excellent layer adhesion – your parts won’t fracture or snap under excessive loads.

All while keeping the density lower than weaker filaments.  

Currently there are a few varieties of Carbon Fibre reinforced filaments available. Most are blended with more traditional materials (like PLA or ABS) that you’re familiar with. We’ve taken a different approach.

You see, it’s not just a case of adding carbon to an existing material to instantly improve it. You’ve got to ensure the properties of the host plastic actually compliment that of carbon. Otherwise you end up with something very brittle, crumbly or otherwise no discernible improved qualities over the original non-carbon filament.

Our mission with this material was to create the highest performance 3D printer filament currently available. This means the best of all the traits you need in a high performance filament, while still getting excellent printing reliability and finish quality.

This material is not intended for printing desktop trinkets and at this price – we think you’re aware of that. Unfortunately getting all the variables right of these high-end materials to print perfectly is painstaking work – the price has to reflect this. We understand our Nylon Carbon Fibre Filament isn’t for everyone.

If you need the best filament currently available, with no compromise – then look no further and order a KG or a sample today.

Carbonyte PA12 CF - a good choice for structural parts

Carbonyte PA12 CF is an carbon fiber reinforced polyamid PA12 filament. It prints without any problems (Anycubic I3 mega, 0,6 mm Microswiss A2 hardened nozzle, printbed carbonfiber epoxy plate from Ahltec, Adimide adhesion improver, 260°C nozzle, 80°C bed, 30 mm/s), has a very good flow, perfect bed adhesion, perfect layer adhesion, no warping at all even if printed with 100% infill, and a very clean-looking print surface. The tensile strenght is about 66 N/mm² in XY-direction and about 12 N/mm² in Z-direction (own test) which is in the same magnitude as other PA-CF filaments. Altogether very recommendable for structural parts which carry loads with major stresses mostly in XY-direction. Considering all advantages, its worth the high price.

Still assembling my new Modix BIG 60 V2 dual head 3D printer on which I plan to run your Carbonyte filament. I'll try the Carbonyte first, once the printer is assembled and tuned. John Gotthold

Not fun...

I was really looking forward to using the Carbonyte, especially after all the positive reviews and stuff. Unfortunately, even though it printed well, and looked like every video I saw, nowhere could I find reasons for shrinking in Carbonyte printed parts. I was astounded, and every forum I asked, CF Nylon isn't supposed to shrink, and I saw people posting photos of CF Nylon printer parts and what not. For myself, I would have shrinkage of at least 0.2mm to 0.5mm, which would make tolerances VERY tight for most precision printed parts. Made the entire roll completely useless, and I made the mistake of buying a 1Kg roll. A lot of wasted filament and time. :(

Hi Ibadat,

Thanks for taking the time to leave this review, although I'm sorry your not happy with your Carbonyte.

Shrinkage is normal for Carbonyte just like when printing with any molten plastic. 0.02mm to 0.05mm is in the range we would expect.

I suggest trying to print your part slightly larger to allow for the shrinkage.

I understand if this doesn't suit your needs so please just get in touch and I'll see what I can do for you :)

All the best,
PA 12+FG vs PA12+ CF

hi PA12 + FG is a great filament - easy to print the objects are rigid and stiff with a level of flexibility the PA12 + FC is stiff not so flexible and breaks easy so between the two filaments i other vote for PA12+ FG great material for end parts
