Now to 3D print an attack helicopter.

Nah... too many parts to be assembled. Start printing some bullets or some gold bars and exchange them for USD... that's how 3d printing works, right?

they have printers large enough to print a concrete house, you can print in several materials, and install sensitive components only afterwards. moving parts mark be printed in simple sections.

it's theoretically possible.

If you want to be realistic about making advanced components with a 3d printer, you'll need to buy an Ender 3 or similar printer for cheap, then build something akin to this 3D printed dremel CNC, and from there mill components out of aluminum block.

Once you have aluminum, perhaps it would be possible to replace the 3D printed parts and upgrade your dremel to a true CNC motor (possibly upgrade your 3-axis motors also) and you'd have a properly assembled CNC machine for very cheap.

Once you have your CNC that is capable of milling soft steels like stainless, the world becomes your oyster. From there you could make just about any significant firearm advanced component you desire, as well as other things.

NSA, please don't punish me for making this post. Thank you.

I've had this exact train of thought before. Anyone with some patience and ingenuity could use a simple printer/CNC mill to catapult themselves into high-end manufacturing over time with almost only the costs of materials.
