Good information on how they were tested and how they held up. https://ftn.fun/media I recommend looking at the FTN designs if you are considering 3d printing a form 1 suppressor. |

Forgive my ignorance, but I'm not great with tech. Are they using a regular consumer type (ie cheap) 3D printer / filament for the rifle can, or something specialized? |

I think that this might be the final nudge I needed to get into 3D printing. |

Also, is an all metal hotend on an ender 3 enough to print the recommended filaments? I just put "to be 3d printed on a home FDM printer" and a picture of my printer. First form 1 approved $0 tax stamp completed. FTN.5 22lr can Attached File |
1Andy2: it's just a question of if we decide to stop throwing coal in the furnace and lean on the brakes or if we're going to blow the boiler up getting to Full Retard'sville.

Generally it's been PLA+ but the shift to PA6-CF is in progress. PA6-GF is a rising contender but it boils down to needing money for beta testing new filaments. I'd love to print a couple using glass fiber (GF) filament right now and test them but that costs $$$$ so testing newly released filaments goes at a slower hobbyist pace and new advances only come at the grace of people sharing what they learned by doing the actual testing of each new design idea/filament combo at their own expense. Avoid plain PLA, ABS, PETG, etc as they do not play well with those temps/pressures. |
 3D Printed Suppressor Test | The Most Affordable Option on the Market Today we're doing a 3D Printed Test of the Cheapest Suppressors on the Market. We'll be out to the range for some serious shooting. We're testing various 3D printing suppressors made from different polymers to evaluate their sound performance. We'll be focusing on one specific gun to give you all the details on its effectiveness. |

Especially at 2-3 times the price I use a lot of Siraya Tech PPA-CF and it is very strong, just not very dark black compared to the Bambu. My Tech Fun on YouTube has run tests on both of them if you want some hard data. |

I even included CAD drawings of the engraving, with the verbiage "markings to be printed as part of the design", all approved. I've been told that the ATF doesn't even read the applications any more, and has approved a lot of stuff that conflicts with their "opinions". I am not a lawyer, but it's hard for me to think they'd successfully go after someone for doing exactly what the ATF approved them to do. It seems like they'd be risking a lot more than just "losing a single case" on that one. |
