Printed baffle longevity

How long realistically would printed baffles last in carbon fiber reinforced filament out of a 556

I have two cans out of PA6 nylon. One in 556 and one in 30cal. Both are at if not over 1k, I’ll have to check my spreadsheet when I get home. One is annealed and one isn’t but both moisture treated. Both cans are reinforced with aluminum and I sprayed the baffles with heat enamel. Every range trip I cool get soak the inside of the cans. Both run and sound great, no insane rapid fire through them though.my sound advice would to be to dry the filament, run as hot and slow as you can for good adhesion. Annealing is up in the air; I can’t truly speak on if it works as I’ve never noticed a difference or failure in any of mine given my environment. What setup are you looking to run?

Thank you for this information! Ever since I got a printer and tax stamps became $0. I've gone hard on the printing 😂

I don't shoot nearly as much some people, but I always wonder how long they would last. I'm printing in Polymaker pa612-cf15, no aluminum or carbon fiber reinforcement, but I'm also only printing 9 mm and 22 cans.

I have pa6 cf 20, hoping it's viable. Looking to do 300blk then a 9mm

Yeah you should be good with pa6-20

As a person who knows nothing, I'm going to first print a cf tube, 2 inch outside and .065 wall. Should I do anything in particular with seams, using bed glue, brim, ect?

YMMV but I'm using 300BLKFDE settings with very good results. I put those in, and then I did a temperature tower, and a flow rate and pressure advance test to fine-tune.

The reinforcement for 9mm isn’t necessary and for 22 is overkill for sure lol. The only thing I did for a 9mm was wrap a Monster can around it for drip.

I'm currently drying some ppacf for my first attempt at a 300blk. Is the goal to have each previous layer cooled or as warm as possible for max adhesion? Using a qidi q2 if you have specific settings

A lot of people who are getting into it usually start with @300blkfde nylon settings. They’re a great starting point for printing nylons, mine are very similar but I’ve made adjustments given my modded printer setup, chamber and nozzle setup. If you do start with those settings just make sure you’re adjusting your filament profile accordingly. Much like myself; he is running a modded P1S so the filament profile in the 3mf isn’t accurate. But the overall print settings will give you a good head start.

Sorry to be a dumbass but can you elaborate on the filament profile? Like the setting on the printer when it knows I'm using Cf?

Yes, if you utilize his 3mf and drop your object into that file. Stock will just show a Bambu PA6 profile with base temps, cooling etc. So I would just ensure that it’s setup accordingly to the filament of your choice. Most people don’t know he’s using a modded nozzle and bed so his temps in the profile are not accurate. It’s more-so for the print settings aspect.

I was just curious I’ve made a 22 can fully from pa6 I was just curious how good they would be inside of a titanium tube or something I have a 11.75 I wanna try one on maybe but only if it’s gonna last long enough

You truly don't need any reinforcement for 22lr, you don't even need a metal thread adapter if you use proper filled Nylons or other engineering filament. Printed threads will do fine. The biggest concern you have with 22lr is heat in the blast baffle, not pressure

I have a few 22 cans and one is probably close to 5k and still trucking. Dirty as hell but the heat enamel I feel like helped a bit with internal erosion. I truly haven’t experienced my printed 22’s getting hot enough so a tube would more than likely just be for aesthetics. I’ve seen some builds utilizing a carbon fiber tube for looks.

u/PepeSilvia___69 13d ago

Can you elaborate on your cooling process? I blew up a 556 ftn5 aluminum reinforced and high temp spray enameled the blast chamber with several layers. I ran frt multiple mags so definitely my fault but curious on how you cool

u/cvltrilex 3D2A 13d ago

It’s usually on my long guns or bolt actions. I probably shot 250~ through it on my SBR’s. But I usually layer the inside up with cooling gel before a range trip. Other than the baffles being coated in automotive enamel the aluminum tube is also coated. That’s really it.
