how do you properly anneal PETCF? is there a guide somewhere?
i can second that ABS is a very good midgrade option. It works very well better than PLA+ under nearly all conditions, besides being ever so slightly weaker to shock loads. its is much more resistant to temperature though, so it really does help with suppressors.
you're going to experience a lot of differing opinions on this one. what makes a "good" suppressor? your typical metal "good" 556 suppressor is way too small in my opinion. but that's just my opinion. you probably won't find anything of a similar size that suppresses as well as the bigger ones we make. You will probably find that we make quieter suppressors that are gigantic compared to "commercial" options. the OD of a CF tube FTN4 is about 50mm and the useable internal volume is probably 2-3x that of a commercial metal suppressor. This is not something we do out of choice, but neccessity. the suppressors must minimize peak pressures to survive, so they are naturally bigger with more expansion volume which instantly reduces peak pressures by allowing the gas more room to expand before it acts on the walls of the suppressor. the materials we use have a yield strength of approximately 10-30kpsi, while metals may have a yield strength in the high tens or even a 100kpsi or over, in specific situations.
the effect of this increased volume is usually that it actually is just quieter.
but if you ask me commercial suppressors are snake oil anyways.
I can get you in contact with Vostok if you DM me. He got pretty mad about odysee nuking his stuff. If you contact him directly you can probably get the files. Like i said, hit me up and i can get you in contact with him. element or telegram.
what a beast
