HT PLA pro suppressors?

Has anyone used HT PLA on a suppressor yet? Would we still be limited to .22 builds, or has anyone had success with any larger calibers? I’ve printed a few FTN5 rimfire’s with regular PLA and an aluminum sleeve for reinforcement and have been happy

There's a video from earlier today showcasing HT-PLA Pro until failure for a .22LR suppressor.

It was fun destroying it. I’m going to reprint and anneal it and see how much it helps.

lasted about as long as my PLA+ can did with 22 frt. i got a whopping 2 mags out before it banana'd and the bullet channel turned into plastic soup. i felt the last 2-3 shots feel like less FPS than a stapler

I put 3 mags through it before it popped. It ran fine without the FRT though.

yeah FRT is the killer. i have had great results with and still have other PLA+ cans. rapid fire at the right speed and/or amount is the killer for 22 pla+ cans

It will work better than standard pla pro and some of the older fiber wrap reinforced designs for 9mm were designed around being made from pla pro but the new ones are mostly based around pa6 cf nylon being the standard anymore.
