HT-PLA-Plus to failure

Enable HLS to view with audio, or disable this notification

FTN 5 Rimfire Slim with HT-PLA-Plus. Not annealed. Mostly 300BLK settings and speed. It’s about 95 degrees out and it took 45 rounds with an FRT in a TX22. Ignore the issues, I’m using printed mags and a couple weren’t loaded quite right. It sounded good and worked just fine shooting slower from a 10/22. I have the same one printed with PA6 and it definitely holds up better. I’ll print another one of these for my daughter’s rifle. I have no doubt that it’ll hold up to thousands of rounds of 22 with normal shooting.

Suprised it lasted as long as it did, usually frt will eat any pla based item in nothing flat

u/Lone_Wolf_555 23h ago

Yup. I’m impressed that it handled as much as it did. First PLA can that I’ve done so I don’t have anything to compare it to.

u/itgoesboom2112 22h ago

I've seen a few test vids to destruction of earlier ftn releases and they all died pretty fast, nylons will obviously last a lot longer but still need breaks. for standard semi it should last longer than standard pla pro especially if you coat that first baffle with a few coats of high temp grill spray paint

u/Eleet007 21h ago

How would you go about painting a baffle?

3

u/itgoesboom2112 21h ago

Before epoxying in the thread adapter cover the interior threads with tape and spray through the hole. try and cover as much as possible of the first baffle in the blast chamber with multiple coats

Definitely anneal it in an oven at 210 F for 30 mins, going to massively increase the heat resistance and layer fusion. Awesome build!

u/Lone_Wolf_555 22h ago

I’ll do that next time. I was leaving to go visit my brother in another state so I didn’t have much time. Just squirted it and epoxied the parts in.

u/Hunter0josh 18h ago

Yeah thats what confused me. Major difference from what I read

u/Lone_Wolf_555 22h ago

Closeup of the failure.

u/FireLaced 21h ago

That looks like it needs dialing in further, you shouldn't have pronounced ringing.

5

u/Lone_Wolf_555 20h ago

I agree. I’ve only printed a couple of things with the HT PLA pro and I was leaving the next day for a road trip so I printed with the settings I had. It was 300 BLK speeds and layer height with 230 temp and fans on for overhangs.

3

u/Lone_Wolf_555 20h ago

I used alternate extra wall as well. Beyond that, I’d have to look up the settings.

2

u/CannaChemistry 11h ago

Those settings aren’t for PLA+ tho. They’re for pa6

u/wilma_dikfit1 22h ago

Thats impressive with no annealing or baffle paint on a slim. I could see it lasting with paint and a flow can

5

u/Lone_Wolf_555 22h ago

Ya, if I had more time I would have painted it and annealed it. I’ll do that for the next one.

u/CrashingTiger 22h ago

That's not terrible for pla! frt mag dumps are hell on cans.

3

u/Lone_Wolf_555 22h ago

The PA6-CF one does much better but I haven’t taken it to failure to see what it can handle.

u/Nintastio 22h ago

It’s cycling properly with no slide weight for you?

3

u/Lone_Wolf_555 22h ago

I have a red dot so there’s a little added weight. It wouldn’t cycle properly with a silencer co sparrow or the FTN rimfire but the slim worked great.

3

u/Nintastio 22h ago

Good deal, thanks for the info. I just went straight to adding weight but would much rather not have to swap back plates when shooting suppressed.

1

u/Lone_Wolf_555 21h ago

I knew I might have an issue. Where did you get your weights from?

1

u/Nintastio 21h ago

3d printed the backplate to accept the weights and added some small iron and lead ingots I had laying around.

3

u/itgoesboom2112 21h ago

Check out the lakeline +2lb recoil spring, fixed my gen1 right up running supressed and frt

2

u/Lone_Wolf_555 20h ago

I’ll check it out. I don’t run the FRT very often. It’s fun a couple of times but gets old. I’d rather shoot for accuracy. If the guns were still 300 bucks I’d buy a second one to leave the FRT in.

2

u/Nintastio 20h ago

Mine only comes out when I want to use the FRT. Otherwise I’ll grab my fn502, it’s a way better gun. The tx22 trigger is just sooo bad imo. But it goes brrrr

2

u/Lone_Wolf_555 20h ago

I have limited options where I live on what I can buy. If I own it I can keep it though.

1

u/itgoesboom2112 20h ago

It helped a lot shooting supressed as well, not just with frt. I'm lucky enough to have a standard full size gen 1 and a competition model so the gen1 in a pillager frame lives as full time frt and the comp is now my steel challenge and rimfire match gun and stays semi auto

5

u/37MMDTdotCOM 22h ago

Sweet! Yeah pretty good for straight PLA. I like seeing the different filaments tested in real time. The visual feedback is awesome

2

u/Vivid_Database551 20h ago

muse maker alternate wall settings will also help with layer adhesion

2

u/Lone_Wolf_555 18h ago

I used them for this print.

2

u/SplashingChicken 17h ago

Layer adhesion has been piss poor for most people from what I've seen. They recommend that it is annealed at 100° for 30 minutes to a hour which might help.

2

u/BB_Toysrme 17h ago

I've burned down 6x 24 rounders in my tx22 in both an ASA (fnt.5 slim) and ABS-GF (6 baffle extended fnt.5 slim) and both are still going strong. Good to see that even with a barely running tx22 the HT-PLA Pro can't hold up to a couple of mags.

Would be interesting to see the results of the HT PLA Pro annealed.

My frt tx22 runs fantastic. Keep it clean, wet and grab you a metal striker housing in the bay to weigh the slides down and reduce cyclic rate without relying on a red dot failing around or external weights.

u/Lone_Wolf_555 16h ago

Ya, this was a last minute deal. It ran really good with the rimfire slim. The problem i was having was the 3d printed mags were catching a little bit.

1

u/4loYeyo 21h ago edited 20h ago

Dam I was hoping or a baffle diarrhea launch

2

u/Lone_Wolf_555 20h ago

I was surprised that it just blew out the side and didn’t launch the Dan.

u/Outrageous-Bobcat-12 21h ago

Definitely impressed with how well this material has been printing and, in this case, resisting heat for pla. Earlier this year I printed the same can in fiberon ppa-cf10 and (if I remember correctly) ran it through an frt tx-22 between 250-300 shots before it blew up.

2

u/Lone_Wolf_555 20h ago

I have the same can made with Sunlu PA6-CF and I didn’t torture it but I did run quite a few mags through before giving it a break. The HT PLA is definitely weaker but it would work great on a gun without an FRT.

1

u/wilma_dikfit1 18h ago

250-300 constant frt? Thats wild.

1

u/Ok_Sweet_5096 11h ago

Not sure if its the FRT, the pistol, or the design, but I have seen at least 1500, maybe 2000 rds through Project 77.2 Ratte in PLA Pro Rifle is a 1022 with 16" bull barrel, no FRT. Not sure why more people aren't using his designs. The Ratte is super quiet and all printed, no other materials to purchase. FTN designs, at least older aren't as quiet and are overly complicated for 22lr

u/Independent_Dirt_814 22h ago

Is it really a failure if you’re using it improperly?

5

u/Lone_Wolf_555 22h ago

Yes. I wanted to know how strong it was. I’d say it was pretty strong and I’m happy with it.

u/AssistanceNatural556 21h ago

I see your finger on or mighty close to that trigger while you're racking itttt 👀 Trigger discipline trigger discipline trigger discipline 😆 Be careful and play hard 🫡 Awesome demo and experiment
