Need help finding 3d printer that supports carbon fiber filament

Hello there, recently i heard that you can get carbon fiber filament for your 3d printer. However, i don't know which printers currently supports the material, other than a printer that cost about 9.000 dollars (which is above my budget). So my question really, i guess, is it possible to modify or replace some parts on a printer to allow it to print with the material? I learned about it through this article http://makezine.com/2015/09/11/carbo...ruins-nozzles/ is it possible that i will have to replace the extruder as well?
Also, if you know how this could be done, what printer would be suitable, if all it has to do is print precisely and support a lot of materials (and preferably a descent - large build size) without considering design, user friendliness and such.

Thanks in advance:)

at the end of the article you link to they say where you can buy an extruder that will resist abrasion of carbon fiber:

i'm printing with this filament on ym Felix 3.0 printer:

it's awesome. I think most 3d printer can print with this filament. YOu might have to change the extrusion tip at some point, for a tougher one, but it works.

Yes most 3d printers will be able to print carbon fibre filaments but carbon fibre filament is extremely abrasive and can rapidly wear out a 3d printer nozzle. So you will have to replace the extruder nozzle frequently depending on how often you print with the filament.

Hi,
To be precise, carbon fiber-filled filament exists, you can find PLA, ABS, Nylon and PET with cut carbon fibers. You can print that on the same printers you would use for standard PLA, ABS, Nylon and PET.
You will wear your standard nozzle very fast (brass is not abrasion resistant), so you can either change them frequently or invest in a hard steel nozzle. Those have drawbacks too as their thermal conductivity is lesser.
The more expensive printers that you mention actually do fiber roving, a very different endeavour and mechanically much more sound.

Thank you, this was very informative - i actually didn't know the exact difference between the normal 3d printers and the fiber roving versions.
However, because the normal 3d printers only use a mixture of a plastic type and carbon fiber, doesn't that mean you won't get the same strength when printing, compared to a printer specialized for working with fibers - fiber roving > carbon fiber, plastic mixture?
nevertheless, I'm happy to know that it actually is possible without having to invest in specialized hardware.

what you actually want bto look at is the markforge printer. That's the only machine in the world that prints with continuous carbon fibre, kevlar, fibre glass etc strands.

Uses a two extruder system that incorporates the continuous fibre within a standard plastic.

$5.500 - But it can make items strong enougb for final use.

The best composite material I've used is a carbon fibre reinforced nylon filament. Expensive - but pretty much indestructible.
And also the only nylon I've tried or heard of that it warp free !
And once you've tried printing nylon you'll understand just how amazing that is.

Interesting, never heard of this one. I wonder how it compares to Proto-Pasta Hi temp Carbon PLA:

Wish we could see specs. Nice to see the "hammer test" on Mymat webpage, but specs would also be welcomed.

I like the finis of proto-pasta carbon PLA. I printed this bracket once, nice finish, even at 0.2mm layer:

i could do better at 0.1mm and slower print.

carbon fibre PLA has no real comparison with carbon fibre nylon.

The pla is - obviously - much stiffer but also can break and shatter and chip.

The nylon one is less stiff, but virtually indestructible - it's reinforced nylon :-)

Both will wear out nozzles if you print enough of them.

makes sense, might give it a try. YOu bought it from that store i presume ? good service ?

Aardvark,

I have a sample of that fibre reinforced nylon too, which I have not yet tried.

What did you use to bond it to the heatplate and at what temperature?
