I don't pretend to know anything about 3D printing, but a quick google says PLA+ melts at ~450*F... a center fire rifle suppressor will easily reach that with any kind of rapid fire.
All of the 3D printed suppressors I've seen in person were metal. I wouldn't gamble the wait and $200 tax stamp on any kind of polymer.. |

That's what surprises me, given that a metallic suppressor can hit 600-700F in a relatively short time, even recognizing that most filaments are going to be better insulators than they are conductors. I just struggle to wrap my brain around it given the gas temperatures at play.
Another link with a video of some thermal imaging along with some info on why it works. |

The gamble should be relatively low risk. If you add a washer to it, you can engrave the washer, and the rest becomes repairable - in theory you should be able to re-print any repair "parts" sans the washer and still be legal.

That is the working theory on them at the moment. But mostly a don't ask don't tell.

The size washer used for the FTN.3 to print your serial number has gone from 98cents to $8.98 on amazon. Supply and Demand working in real time. Also CF tubes that fit have also gone on back order.

I'd love to make one but the kits are just too much. Anyone have a source for something reasonably priced?
I really need to change my signature. Just bought my first new Miata in 10 years. '91 with an FM Stage 1 on it (no electronics). |

You also need to update your location since you moved. Go buy a MKE AP5-P and take it apart to built the KM5 or the SF5. The AP5-5 is only a few hundred more then the parts kits needed. Do you already have a 3dprinter rob? I would also recommend starting out with some easier builds before going straight to the KM5.

Yes, need to update the location to TN. I bought a 3D printer in 2018, I think after you started talking about yours. Started with an Anet A8, then Ender 5, then Neptune 2, and currently have a Bambu Lab P1S. FWIW, I graduated from my K40 with a cooler full of ice water to an autofocus Omtec AF2028-60 with a CW-5200. I think it was a lot of money to spend on a hobby system that I only use once a month but it sure is nice. I'll take a look at the MKE AP5-P, thanks! It is a shame that since I bought 30 acres in Bum Fuck Egypt I never shoot. I need to change that.
I picked up a AP5-p last year. The Turkish Lira dropped a ton and you could find them for around $1000-$1200. They may be a bit more now, but it is a ton of fun to shoot. You want to make sure you get the tri-lug version. No real differences between the full size and the shorter one. Mostly a personal preference between the two. If you just want to HK Slap you can build the FGC-9 MK2 or Stingray version. Those were built to be slapped. I think total build cost is around $200-$300 depending on how much DIY you want to do. |

I wish you the best of luck with that Dead Air. Only thing I know about Dead Air is that they completely fucked up the RMA's of some of the suppressors and have the people angry.

I finally did an eform1 yesterday afternoon for a 3dprinted silencer. People are getting sub 24 hour returns. I realized my fuckup was doing it Friday afternoon. No way the ATF is approving it on a weekend. So hopefully sometime next week I get it, then my printer goes squirt squirt squirt.
I am looking forward to my local range going cray cray over a 3dprinted silencer. They are a bit FUDDish, but good people overall. |
With the vastly decreased wait times, I've been toying with the idea of a dedicated can for my .300BLK.
Interested to hear (pun intended) how your 3D print experiment goes... |

Just got my eform1 for a suppressor back. Less then 7 day turn around time. Time for the 3dprinter to go squirt squirt.

Today I printed. Tomorrow I epoxy. Next week I shoot it. |
Heading to my NFA dealer tonight to do a pair of eForm4's for two Polonium K's to live on a couple of my 16" AR's, one of which is set up for Run n Gun.
