I was watching some videos, they look pretty sturdy.
Apparently rebels in Myanmar are even using them.
Don't they still use metal parts? Or was it 100% 3D printed?
The ones used in Myanmar are variants of the FGC-9 which indeed contain metal parts.
Currently the most common method of creating 3D printed guns are buying parts kit and printing the reciver (housing) for it. But the FGC-9 is specifically designed to be able to be made without any controlled parts, including the barrel. Any metal parts used can be bought in a hardware store.
