Have Donnyfl and Huma Moderators. Want to try some thing different.

I've been 3d printing my own for my lower power guns like 16-40 fpe (beyond this prints are not durable enough). Tried all kinds of designs. Some based on lung anatomy, some that strip air and send it backwards, others that strip air and send it forward, one that held water (read about water based suppressors), vented and unvented, different baffle angles and spacing / density, reflex designs that shroud barrels...



It sounds like you collect ldc's Printing your own can be fun. If I cover my 3-D prints with epoxy it binds the layers better and then they can stand much higher pressure.




 
Depending on what you intend to install it on, you may be able to get one of Neil Clauge’s “Reflexed” type moderator’s custom made... they will only work with certain barrel styles. If you decide to contact him, be sure to mention the term “Reflexed” in your inquiry, and specify you want the overall added length to be as short as possible and still be effective. He does outstanding work. Everything he builds is custom per each individual order!

I think the way forward is using stronger filament for the core/baffles and end caps and then using a pre-fab carbon tube. Any particular baffle setup you got luckiest with? Simple cones seem to be the most effective for me so far

How does the Sarissa compare to Donnyfl’s moderators? This looks to be maybe the size of the Shogun? Hard to tell.

Anyone compared them?

If you leave more space before the first baffle the pressure will be lower when it reaches it. I've printed them from pla+ for the last two years and only had two where the edge chipped a little. .30 impact at 132 fpe @ 150 bar. I print them tight at .007 over bore size. They're so much quieter than the Sumo I had that I sold it within 2 hours of testing them. The sound of the .30 hitting an animal is still pretty loud though.

Yes - I have a Shogun .25. The diameter is the same as the Sarissa and Falx. The Falx is 1" shorter than the Shogun and the Sarissa is 2" longer than the Shogun. IMO the STO moderators are quieter yet have a slightly higher tone to them. The Shogun is a bit louder, but the sound is more on the low end of the Hz spectrum. 

But - keep in mind that I can only speak to the high flow insert version I'm using on my EVOL and Leshiy 2. The STO has multiple internal inserts depending on the air flow of you gun. Read their blog - it's very scientific and their testing is extensive. You need to read their website and do a few calculations to figure out the best insert for your particular gun. It's not a one size fits all.
 
132 fpe in pla!? Must be a nice design... I'd love to get a look at a long-section.


I now have air stripper first stage then larger gap for first baffle then closer baffles near the end. I have not had luck with close tolerance - I get clipping too often. So the sound reduction is comparable to other ldc's and not exceptional.


Using an oem FX suppressor you can leave sections empty if you want because each section has a lip to hold the baffles. I make the baffles to fit snug for precise alignment. When I printed them for others I included a few extra in case of erosion over time. You'll see exterior strands start to erode before any other problem.
