Is it far fetched that 3D printers will be able to print nukes using radioactive materials?

It may be possible, but it wouldn't really get some third world country (or home tinkerer) any closer to producing a nuke. Getting enough weapons grade uranium or plutonium and developing an efficient design are much bigger hurdles than the actual assembly.

Yes, it is far fetched. 3D printing is going through the usual start-up issues, where people think the technology can do things that are simply not possible or practical. A step closer might be CAD/CAM, since shaping metals that have high melt points is more practical than trying to squeeze them out of a nozzle and attain tight tolerances. Personally, I don't see this as more than a flight of fancy anyway. It is not a do-it-at-home project, and governments have their own ways of doing things.

One would need a pretty darn large printer.

It's like printing a dog. It may look like a dog, but if it is not made of the correct component materials, it won't bark or fetch.

They'd need to 3-D print a lot of cyclotrons (or a reactor) first? All joking aside, the actual fabrication of a nuclear device is probably the easiest bit.

This. Obtaining weapons grade plutonium and developing an effective delivery system are more of the problem.

If you mean is it far fetched for 3D printers they are now to "print" a nuke, then yes. Somewhere down the line, it may be possible through some later version of the technology.
