Prosecutors showed in court how the men planned to use 3D semi-automatic printed guns to launch the attacks on ethnic and religious minorities, key infrastructure and political opponents.
The guns pictured in the article look like variations of the FGC-9. The files for that one are fairly easy to find online, as are tutorials explaining to complete novices how to make one from more or less scratch, including machining rifling into the barrel. The design itself is reliable enough that it’s being used by rebels in Myanmar. All of the pressure bearing parts are metal like in a more conventional firearm, so the most likely failure model for one of these is a non-explosive crack in the frame.
This is all to say that a mildly experienced printer has a pretty good chance of making a fully functional semi-automatic gun using this design.
