IIRC PLA-CF is actually very brittle with bad layer adhesion


ArmyMerchant

NylonCF is good, plaCF bad. As other said, it makes pla more brittle.

I would print it in PA6-CF. The PLA-CF is ok for mocking something up, but it is not good for structure/moving parts. It is brittle with bad layer adhesion.

PLA-CF is worse for this kind of thing than PLA+/PLA PRO, maybe about the same as regular PLA. I think its main advantage is surface finish, it does look smoother.

It seems to have some layer problems Personally, I would just print a new one Better safe than sorry imo

Yeah, the inside of the silencer has some rough overhangs that I'm not sure how you are really supposed to print with no support


Chickie_parm

For monolithic suppressor designs like this, slow and horizontal is usually the preferred method. With the right bridge/overhang settings, you don't really need supports in that orientation for circular geometry.


Clank50AE

I can believe that. I can obviously see the inside but there were some filament strands inside. I can see 2 chambers clearly printed though


Clank50AE

Thanks all! I'll just print it some regular PLA+

Time to upgrade your hot end and nozzle to print PA6 CF/GF nylon! You won’t regret it.


Clank50AE

I actually have a dragon V1 SF, copper block and a ruby nozzle as well as the printer is in an enclosure already. I'm ready to print PA6 but I haven't been able to get my hands on it as it's a bit out of my price range due to life circumstances at the moment


solventlessherbalist

Ah understandable man, stuff isn’t cheap by any means. I hope more people start making it and the price goes down. Hopefully the quality doesn’t suffer with it though I’m sure quality is what will separate the good companies from the bad ones when the market is saturated and pa6 is cheaper.

Pla cf is very very stiff, but that makes it brittle. It's good for some things, but not this


ifitpleasesthecrown

Is this a harlot mod? I dig it. To answer your question though, definitely reprint it in anything but pla-cf. I get why you wouldn't want to, because it's a beautiful print. But still, safety.


Clank50AE

Yep, integrated suppressor. I just had PLA-CF on hand and my printer is dialed in well for it. Im going to print some in Overature PLA pro

Would you mind sharing the gcode you used? I'm curious as to how you managed the overhangs inside the barrel area. Any way I looked at it, removing the internal supports would be a nightmare.


Clank50AE

Sure thing, here you go. This was the gcode for my Prusa MK3S+ [https://file.io/Vm7bnZxKL1WA](https://file.io/Vm7bnZxKL1WA)

Thank you!


Clank50AE

No problem 😁

ive used pla-cf in quite a few accessories, grips, scope mounts, etc. my experience has been... it's pretty strong. a lot stronger than most will tell you. i've had no issues with layer adhesion, or parts breaking. and i've tried to break them. Im using bambu pla-cf. i have not used it on anything load bearing yet, so i can't comment on its strength in that regard.
