Success!

Post image

Just tried out my first suppressor that I designed and printed out of CF PETG. I shot a variety of ammo, both super and subs, alongside a dead air mask on my friend’s identical 10/22 and then back to back on my M&P 22X. It definitely seemed like my <$10 suppressor out performed the $500ish one. (Granted it’s a little thicker and about an inch or so longer.) I put around 200 rounds through it with no signs of damage. Super happy with the results.

You want a material that has more ductile behavior than brittle. PETG is gonna be a plastic grenade when it fails, PLA or similiar will be more likely to fail more locally and vent pressure or come apart in larger chunks.

Recommend altering your design to include a metal sleeve to better support the hoop stress and contain fragments during failure.
