re written with ai to protect typing fingerprint
I’m working on a custom form 1 suppressor using Obsidian 9 airsoft host. I’ve settled on a baffle stack for the end piece. Since the Obsidian design allows for modular disassembly into smaller suppressors, I’m considering a dual-system approach. I’m thinking of using a long, gyroid-style baffle after the blast chamber—this type seems popular in metal 3D printing. Has anyone experimented with this configuration? I’m curious about its performance and durability in this application and if it worth pursuing
Gyroid baffles in 17-4 or inconel sure, but even in PA6-CF that’s going to be a no go. The material will simply be too thin and will either deform rapidly or break due to the forces especially if close to the blast chamber where pressures are the highest. What caliber are you making this for, barrel length, and what material/thickness is the airsoft suppressor? There’s a reason every 3D printed suppressors design that works for any reasonable number of rounds has thick walls and infill, you need that density to hold up to the pressure and forces at hand.
That’s really helpful, I’m grateful for the information. I’ll search for quality conventional baffles.
I think gyroid baffles in metal cans work well becaus they create a ton of surface area for the metal to cool the gasses. That means the can absorbs more heat tho. With plastic cans I think the baffles would just melt faster lol. Maybe worth a shot with 22
Yes, I agree - it seems plausible. I believe they have a genuine opportunity for .22, so I’ll definitely research it further.
C’mon anything other than 100% infill on a suppressor? Those thin pieces aren’t gonna survive the blast in a polymer config.
I would think the material would be much too thin. Maybe you could try the fill multiline infill option? That should give it more thickness but even then maybe only for .22
I think your best bet would be to run a set of 60 degree cone style baffles and then a set of radial style baffles. This would make it work well with both supers and subs. I have a metal can that I built and it has 8 Dino style baffles and 3 radials and it does amazing. What caliber will you be running would really be your pivotal decision.
The modular nature of the Obsidian 9 platform makes multi-caliber capability attractive. Initial focus spans .22 through 9mm up to 300blk, with the goal of swapping baffle configurations rather than entire units for different applications.
Current 9mm prototype uses interlocking 60-degree cone geometry throughout the stack, complemented by specialized endcap baffles and silicone wipe integration. Performance exceeded expectations significantly—initial range testing produced suppression levels that suggested reduced powder charges, though standard loads were confirmed. The acoustic signature reduction was remarkable.
Next phase involves evaluating various mounting interface options once additional hardware arrives. This will determine optimal attachment methods and identify any compatibility issues across the intended caliber range.
You won’t have much volume in it though because the baffle size will only be like 1.32” which is too small for 300 blk and almost too small for 9mm. I have the exact same style but in the surefire socom and it truthfully is t big enough for anything other than 22 and maybe 9mm subs.
I’m with you—I thought I could squeeze more out of 9mm, but I think I’ve hit a wall. You’re probably right that it’s time to move on to a better host like my Huxwrx 7.62.
I’ll DM you the site I use; I’d rather not post the link out in the open for everyone to see, because… reasons. If you see anything else on there that looks solid besides the Hux, definitely give me a shout. I’m really just trying to build a clean multi-cal setup that uses a standard thread adapter so I can finally get away from that 14ccw stuff
side note- why the AI re-write sound kinda human this time? lol
