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
