Building a rocket shell is probably just fine: you need to fuel yet - that you can't 3D print. probably fine...

Overall 3d printing is a lot more than ghost guns and ghost rockets. That the conversation dominates this small sub-section reeks of 'think-of-the-children' screeching that hides explicit power grabs in regulation and surveillance with the main intent seemingly to be 'enforce copywrite' (of only the big players that can afford to throw their weight around).

Fear pushes people's buttons.
