This website will serve as the home of the FTN suppressor series as well as a collection of information for 3D printed suppressors.
Part of the impetus of our work was the ATF policy change regarding form 1 suppressors. Any premade suppressor such as a solvent trap was redefined as a suppressor. There was previously a very active form 1 community.
After the rule change, the ATF specifically stated that 3D printed suppressors were one of the examples of allowable form 1 suppressors. I believe the reason they allowed 3D printed suppressors in the rule change was because at the time, nobody thre could have imagined suppressors that could handle more than 22. The rise of 3D printing has caused the barrier to entry for homemade suppressors to be much lower. The suppressor market is also not subjected to typical market forces due to the NFA. There is a complete missing market segment of consumable cheap polymer suppressors. Even cheap metal 22 cans should cost less than $20.
3D2A is a perfect avenue to address this mismatch.
Around the same time that the ATF was changing their definition on form 1 suppressor components, they were also going after pistol braces. This turned out to be a blunder, as a very small percentage of people who had a braced firearm registered for the “free” stamp. This has shown once again that mass noncompliance works.
Marijuana has also shown that mass noncompliance works.
Our goal is to nullify the NFA. We aim to do this by making effective and cheap designs for homemade suppressors. We want to teach as many people as possible how to make their own suppressors. Even those that register form 1 suppressor are helping us meet our goals, as that is another person who has learned how to make their own suppressor and gets us closer to common use.
The landscape has changed again for 2026. Tax stamps are (for now) zero dollars. This represents an unique opportunity that may not last very long. A large number of people did not print suppressors for fear of legal repercussions and also did not want to pay $200. For those people, there is now no excuse. It is our civic duty to produce as many suppressors as we can in this narrow window before the rules change again.
If we can create enough suppressors that we get to common use, we may effectively nullify the NFA. With luck, we may even be able to get suppressors removed from the NFA as well.
To clarify our goals regarding common use, even though it would be nice if we hit the nebulous legal definition of Common Use, we are not putting all of our eggs in that basket. Rather, our biggest objective is to achieve common use (lower case). The estimated number of suppressors in the US is 4.8 million. If the US citizenry increased this number by 10x or even 5x, and they know how to easily produce them, the NFA is unenforceable. Suppressor use will be normalized at ranges and for hunting. Even if the majority of people do not own suppressors, they will know people in their lives that do own suppressors. Suppressors has been vilified by movies and the news, and broad ownership is the best way to counteract that. A much larger percent of the voting population will either own suppressors or have family members and friends that own them.
Broad ownership of suppressors is our goal.
