Re: Carbon Fibre


Reference?

what do you mean ?
this is the filament
http://www.esun3d.net/products/198.html

as for baking the printed parts - unfortunately nylon based materials will not improve with baking like other materials .

i got carbonium from https://www.imakr.com/ , PAHP i got directly from treed filaments , contact them .

Re: Carbon Fibre

You said ... "there is no real carbon fiber in this filament . i dont know what they added to the filament but i almost sure its not cf . "

So, where is your reference to this claim, or if it's just your hunch, what makes you say that ❓

just my hunch . its way more flexible then other cf filaments , its even softer then regular nylon filament.
it might also be carbon fiber powder , instead of short carbon fiber chops like in other filaments .

Re: Carbon Fibre

@sergey.s4
Those different filaments, at what "maximum volumetric speed (mm³/s)" did you successfully print them? In Slic3rPE the value for CF20 is 1, and that is slooooow.

i didnt use slicer for long time , even if i did , i almost always use custom settings and not the default values (use simplify3d).
generally i print very slow , around 30mm/sec or lower.i print stuff at night so usually its ready in the morning .i also reduce acceleration (around 500-1000 with M204 command) for the printer to be quieter .

slower speed improves layer adhesion (and printing artifacts) , i'm not in a hurry and want my parts stronger.

few more tips for those who want to experiment and avoid my mistakes :

- i never had a single CF filled filament part detach from the heat bed .(i use glue stick sold by prusa , didnt find anything better) . the only failure i have with CF filaments is when nozzle clogs .
- some of the filaments are prone to warping but most of the time they are much better then non cf filled materials . since i put an enclosure i didnt have a single part warp .
- nozzle , its best to use hardened steel nozzle . dont go for ruby nozzle , its a waste . the base of the ruby nozzle is brass and there's a high chance of damaging it (read below) . if anybody know where i can get tungsten nozzle , or even better tungsten carbide nozzle let me know .
- heater block , to my surprise the stock aluminium block can be warped and damaged even at temps below 300c . i damaged my original aluminium block while printing around 280c . my nozzle clogged ,i tried to remove it and it stripped the aluminium block . the nozzle turned but didnt came out .i trashed the block and the nozzle (glad i didnt go with ruby...) . i moved to copper block since .there is also stainless steel option .
- printing at temps above 300c , well , it sucks lol.
i thought all i need is some pt100 +amplifier upgrade , do some software tweaking and wallah .well yes , i can print at 400c , but the problem is most of the high temp (very expensive) materials warp without heated chamber . well no problem , i have an enclosure , i can stick some heaters inside and make a "heated chamber" (assuming printed parts also made with high temp material) - not enough !
when heated chamber is used , the extruder fan is not doing its job . i had those high temp filaments stuck inside my heat break , making it almost impossible to remove without damage . i'm using titanium heat break now but i dont want to test it again and destroy my shiny new heat break .
if you really want to print at 400c , in addition to heated chamber , you will also need watercooled extruder .
i realized peek is not worth it , unless you need your parts to withstand temps above 200c . luvocon 9742 is the strongest 3d printing material they make for 3d printing . even stronger then their peek .
there is new luvocom material called 9891 , i dont know if there is a filament based on it yet .

Re: Carbon Fibre

The Ruby did not work for me but since I moved to a steel 0.6 nozzle, I haven't had a single print failing due to clogging.
So slow is the key? I will try it, but printing overnight makes me sleep not so well, even when I dont hear the printer and have smoke detectors...

Re: Carbon Fibre

Stringing is the only issue I've had with nylon based CF.

Re: Carbon Fibre

By-the-way, if you want stronger prints, use a larger nozzle: https://www.prusaprinters.org/everything-about-nozzles-with-a-different-diameter/
a 25.6% strenght increase if you move from 0.4 to 0.6

Not CF I know, but has any one used the treed LONGCHAIN nylon. It uses a 90º Bed. Is this too much for the Mk3?

No. I use 110 for CF.

Hi OPK
Did you use an enclosure for the printer?

Re: Carbon Fibre



treed carbonium finally something stiffer then good old pla . this is my go-to "general" filament . harder to print then other filaments , but considerably stronger overall . can be drilled and tapped (no need to insert metal nuts like with pla and other filaments)
withstands tepms higher then 100c , moisture absorption not so bad .

Sergey Thanks for all your detailed responses.

Having ordered and received some carbonium and a sample of the PAHP I guess I should start lining up my ducks.
So in no particular order;

  • How have you found the Treed recommended temperature settings?

  • I have 0.4 hardened nozzle. Guess I should upgrade to a 0.6mm but in the short term I will see how it goes?

  • I don't have an enclosure but it is in a very very small room - likewise will see. Is the enclose more about controlling drafts or keeping the space warm?.

  • Important to slow the printing speed as per your earlier post? tech data says 60mm/sec

  • using the PRUSA PEI plate will the glue be sufficient?

  • Not being too experienced I will use the prusa Sli3er. Do you have any thoughts on which of the presets would be the best point of start? the Taulman Bridge?

  • Currently using layer height of 0.15 - seem reasonable?

  • Any other enlightenments?
  • For info I have a spool of the Treed longchain nylon - guess I will be doing a lot of experimenting.

    Re: Carbon Fibre

    You can print carbonium without enclosure.
    I print it in enclosure because i have one for other stuff...
    Print temp 250-260c, no fan.
    If you want good layer adhesion, print slow but not too slow. Start at 30-40mm/sec
    With 0.4 nozzle you might get clogs if you use too much retraction. Set retraction no more then 0.5mm.
    It sticks well with glue stick on pei, bed temp 80-90c.
    It oozes allot, i overcome this in s3d by using nozzle wipe. Somtimes i set wipe to 10-15mm, not sure if you have that feature in slicer.
    0.15mm layer is ok.
    If you print thin and tall objects you might need a fan turned on.
    Make a test print to dial in your extrusion multiplier setting.

  • I'll defer to sergey.s4 on the need for an enclosure for this filament.

    That said, enclosures are about both controlling drafts and keeping ambient temperature warm. They can also be about dealing with fumes & micro-particulates. An enclosure needn't be elaborate/expensive, especially if only for occasional need/use for temperature control--a corrugated box may do. If you plan on more regularly printing filaments that require/suggest an enclosure, something more substantial might be in order. Lots of plans online for all kinds of budgets/complexity.

    That's "MISTER Old Fart" to you!

    Hi,

    Any updates on how did it work?
    I'm in Australia as well and a new MK3 should arrive soon.

    Printing CF filament parts is the main task so I'm very curious to hear how it works for anyone.

    Hi Peter
    I m still work on developing prototypes (and gathering experience) in PLA before starting on CF filaments. I do have a roll of Treed Carbonium ready to go though.

    You may get to it before I do but happy to share info when I have it. Where are you?

    cheers John

    I'm in Adelaide,
    I'm mentoring a team of students taking part in FIRST Robotics Competition and we are looking into using the printer for printing functional robot parts. Our build season starts in January so we need to learn fast.

    Likewise - we will have to compare notes and examples
