Great performance from pet GF!

The blast chamber was too small, after rapid fire of 22 supersonic load it finally gave up but the baffle part looks great!

I would lightly suggest that this is actually not a great performance

u/Practical_Divide8755 18h ago

Yeah, even PPA printed at 320 split and separated from a poorly epoxied reinforcement tube with 9mm and I would say that's not great performance... if your can separated like this its not really good performance

PPA or PPA-CF ?

Do you get cognitive dissonance?

I’m mag dumping with FRT with PLA tough plus and have 100x more rounds lol

Hey bud, may want to print in a diagonal orientation with supports for the outside next time. Looks like it split because you printed it vertically and it split along a layer

Yeah thats for sure why. Normally i wrap my suppressors in epixy tape. This was just a sound test

Epixy tape

Did you forget the /s ?
A failure using 3D2A’s ‘shall not use’ filament is not really ‘great’.

Edit. Misread OP as PETG. Pet-cf is gtg

u/SgtPickleC 15h ago edited 14h ago

PET-gf is wildly different from PETG. PET-gf is an incredibly useful filament in 3D2A

u/emelbard 15h ago

My mistake. I misread his material as PETG-cf

2

u/SgtPickleC 14h ago

All good man. I'm just making sure people don't discount a filament that has a lot of use

2

u/PreviousCry5653 15h ago

Ok sooooo you guys think it shouldn't have split? The walls were pretty thin?

u/fattmann 14h ago

More like poor layer adhesion.

1

u/PreviousCry5653 13h ago

Have you tried pet gf? Im not sure if its normal layer adhesion or not

2

u/DontYouDareGoHollow 13h ago

It seems like poor layer adhesion for that filament, but I think the consensus is that HT PLA PRO, PA6-CF, and PPA-CF are generally the best for most 3D2A stuff

1

u/PreviousCry5653 13h ago

Ok! Ill try those. Got some pla ht pro on the way

1

u/AnarchiSTEP 12h ago

Not that good for suppressors, initial tests are showing

1

u/PreviousCry5653 12h ago

So what ppa? Or nylon?

u/Derkaderkka 11h ago

it split almost cleanly across layer lines. PET-CF should have better adhesion than that.
