/diy/ - Do It Yourself

Anybody here have any experience 3D printing Liberators, or any other 3D printed gun?
I am building a D-Bot and I want to run it on PETG exclusively, and build a Liberator someday, but the specs say that the barrel needs to be made of ABS plastic and then vapor-treated with acetone to get more strength.Now I know that that's to prevent delamination, but PETG is ultra-delamination-resistant already. So I'm basically asking if you can do that with PETG also or if I need to buy a spool of ABS for it.

Also, does anybody have any experience 3D printing any black powder firearms? I found a guy talking and having posted pictures of a 3D printed musket pistol, but not what plastic he made it out of or what the detailed specs are.
