cant wait to see the "how to" on the hardening. I will be using it for all kinds of my 3D prints, not sure if i'll ever make a can, but if its that tough, I'll use it for functional parts around the shop!
When you mention hardening your print. Do you mean you're annealing the plastic? Also what filament did you use on the tan can? Great video! I'm amazed at where this technology has come in 5 years
The tan suppressor is PETG. The entire process is a little complex, but I heat treat the parts in an oven just under their glass temp. I'm working on a process that can be done by the average diy person. Haven't quite gotten it figured out but very close. The intent was to manufacture and sell these but after years of working out the kinks, there seems to be no interest in a non metal suppressor. So it'll probably become a non metal form1 build type for those in the US, and a super economical way in European countries. I'll be adding more vids and probably do a tutorial soon.
@@jeffdill5260 thanks for the reply! I have tried annealing PLA+ in the oven just under it's glass transition temp as well. I use salt or sometimes casting sand to pack the pieces in to avoid heat warping. The problem I run into is shrinkage. Many parts shrink ever so slightly after annealing. I have tried to XY compensate for it but it's incredibly hard to judge due to variables like inconsistent heat from the oven. Have you had trouble keeping the baffle holes in spec after annealing? Can't wait to see more content I really enjoyed that video
For 17 caliber I use a 5mm reamer to make the bullet path consistent diameters. I then use a ground stainless steel rod through the bore so its alignment cannot change during heating. If the bore shrinks at all it cannot squeeze down smaller than the guide rod. If I suspect it shrunk at all I'll ream it again but it's never been an issue.
For 22 calibers I used a .250 reamer and .250 rod. The over I use is rather expensive but is very precise temperature control. It's an oven used mostly in science labs. I'm working on a different method that doesnt require anything other than average tools to build.
@@jeffdill5260 you actually get better results when annealing just above the glass transition temps. It allows the crystal structure to re-align. Anything below glass transition won’t allow full alignment
Pretty much 100% infill... yeah they gotta be 10 walls+ and 100% infill lol. Im sure you've gotten it by now with all the advancements in 3d printing tech. And the "deaf" CAD advancements too. Thank America for providing "deaf" people with cad skills. Lollllll
As I said it was a design downloaded from the web, and I didn't mention the source site purposely. I didn't need to 'get' anything. Our suppressors are assembled in a different way. It was simply a comparison.
Haha, yeah. There's the concern that someone, somewhere is going to notice innocent academic curiosity in stuff like the topic of the video and get the wrong idea. It's just interesting to learn about, though!
Well, they got 11,000 people to individually investigate then. You know how many people have these files downloaded with no plans to use them, it's surprising reading around the threads. I know plenty of folks who don't even own a ed printer and yet they downloaded the files and out them on thumb drives just in case any law gets passed to where you need to provide FFl info to download the file (like in NJ).
As long as you can print nylon carbon fiber filament you can make a printed can with any kind of printer…. Long as you can successfully print carbon fiber…
If there was a steel adapter that doubled as a blast chamber, would that help the non-treated suppressor stay more stiff? For example; 1/2x28 to 1.375x24 with a cylindrical blast chamber, then the suppressor would attach into the 1.375 threads.
This awesome. How many minutes did you do the heat treat for? I have other parts I 3D print for houseboats that under go heat and have been looking into heat treating.
How do you go about heat treating prints anyway? Get a cheap toaster oven, set it at the hottest temperature you can that doesn't droop the item, and let it bake for a bit?
There is metal threaded insert in the muzzle end for attaching to the barrel. The print is regular pla, I have used petg before but I've found pla works best for the rest of the manufacturing process.
I really hope that one day they get rid of the stupid suppressor regulations. A standard rifle round like a .308, through a suppressor, is still as loud as a jackhammer bouncing on concrete - the narrative that suppressors will allow people to discharge firearms in the commission of crimes and the person ten feet away won't even realize a gun went off is ludicrous. If a suppressed gun is fired it still sounds like a gunshot and is still loud like a gunshot. You and everyone around you will know a gun went off. In an indoor shooting range, even with Peltors and those foam rubber ear plugs behind them, a shorter-barreled 5.56 or other high velocity rifle fired with a break from the stall beside you is so loud even through the earpro you'd get the impression it wasn't healthy. That's one of the things suppressors could help with tremendously - suppressors are a public health thing.
Everytime somebody does the legal way and tries to be lagit like submitting a form one to build a solvent trap silencer or in this case a 3d printed supressor. People this is what gives the government the idea to ban these type of things. Doing things the right way in that regaurd and being a law abiding citizen is only rewarded with punishment on the law abiding citizen and the whole 2nd ammendment community. Its almost like youre outing these things that are kind of a discressionaly unsaid loophole type situation. I know thats not peoples intention but thats all thats gonna happen any time you involve "them" in an item simular to these. Like the solvent trap, how many people have you heard say they got their form one to make a legal supressor. Now the atf has people officialy admitting that they are turning them into supressors when thats not what the company stated was their intended use. Its like outing them directly to the government. So of course the atf is gonna acknowledge and ban them. Keep legaly 3d printing supressors and the more people do it the more the atf is gonna see how many people are capable of doing it and how accessible it is and they are gonna ban 3d printers all together. Like cmon theres a good thing and then people who are unintentionally being the teachers pet in a way are gonna ruin it for everybody. I myself in no way shape or form condone doing anything illegal but i can garuntee you if alot of people start sending in form ones to print supressors its gonna ruin the whole 3d printed industry. Just think about it, theres no reward with them in doing right theyll just turn around and take from the law abiding citizen. If you want something like a supressor the rule should be if you dont have the cash to buy a commercialized one legaly then just dont do it or dont submit a form one on anything that can be turned into one. Why help take away everybodys rights just because you think you are doing the right thing. I dunno just my opinion. But i do like your print and respect the effort you put into it and think its really amazing i just dont agree with turning these into a legaly submitted type item. Once again just my opinion from what ive observed
The difference between you printing your own on a form1, and me transferring it on a form4 is about 14 months. That's it... You pay $200 either way, and that's what makes it legal or not. You can get an approved form1 in 30-40 days. Form4s take forever. That's a big reason people choose form1 over form4. Solvent traps were never an exception to a legal definition of suppressors. A single baffle is a suppressor. It's got nothing to do with how easy it was to make. It's a suppressor from an unlicensed manufacturer who did not record the suppressor in their assets and did not/could not legally transfer said suppressor on a form2 or form4. Opinion letters from the atf don't mean anything. Countless ppl are in jail because an atf opinion letter said X was ok. Same with solvent traps. Ignore opinion letters, they are useless. Statutes and reg codes are all the matter. I agree with not poking the bear, but creating one the legal way, is not going to get 3d printers outlawed. It's just another way to do the same thing that's been done since the 1930s. Whether I agree with the law or not, I can not advocate doing something unlawful in public, on youtube. Everyone is free to make their own decisions so proceed accordingly.
@@jeffdill5260 have you seen the news stories already on 3d printed guns? I see it all happening like with the p80s and all the other things they took away from us. First it makes it's rounds all over social media and people making countless videos on RU-vid about it then it makes the news then within a couple years the government has banned that item or put certain laws on them. I dunno if they will ban 3d printers but I see them putting restrictions on it like only selling them to certain businesses or you need to have some kind of credentials to have one something like that I dunno I'm not sure what they will do but i do know its too much freedom to have in their eyes. I do believe they are trying to take away our right to bear arms and anything that can help us create our own firearms which is legal without the intent to sell in most places as we all know if you are legally allowed to own a firearm. I dunno man I see the ARs being taken away alot of things being taken from us it's crazy the world we live in today this stupid alphabet agency can say whatever they want and have it come true most the time. And for the most part it's only effecting the guy who's following the law. Which is the really sad part because criminals don't care about gun laws. It's messed up the good people have to pay for doing the right thing. I myself am one of those people who believe in doing things the right way. But I live in Cali and it's freaking gotten ridiculous out here. The question is when it gets blatantly unlawfull and they slowly start taking our firearms away and it becomes illegal to own one period then what does the law abiding citizen do? Anyways I respect your opinion have a good day
It's still up! Has a 6el yagi at the top, a 5el yagi, just below, and a jpole under that. It's went through several storms in the last 2 years, even a small tornado. Still no guy wires... It works fantastic! I'm going to put up another at a small building and use it for a repeater mast.
It's not really a poi shift. It's a random shot placement from shot to shot that moves several inches, even a foot in any random direction, depending on distances.
@@jeffdill5260 That would most likely be caused by the tunnels in the can. Especially since it's so random. Also, why no clip in any of the baffles? Not only does it improve suppression but also improves the accuracy as the gas is vented off the face of the cone the same way & introduces more turbulence in the suppressor.
It doesnt matter if the baffles are clipped or unclupped, the rigidity of the suppressor body allows it to flex at its mounting point enough that you cannot always predict where poi will be from shot to shot. You can 3d print internals and put them in a steel tube, and have reasonable accuracy from shot to shot. Typically, you could expect the same group sizes with/without the suppresor. Put just a 3d printed suppressor on, fresh off the printer and the poi shift will be substantial from shot to shot.
6:50 Government has no right to tell anyone what they can or can't make or have. You playing their game makes you the criminal just like them. Sad thing it's never psychopaths like you getting their kids shot in the face by the pedolice
First, not psychopath. Second, you do whatever floats your boat. I'm not going to advocate others commit a felony and spend time in prison because you disagree. I gave information to follow current law. If you don't want to follow the law, then dont.
