Even with no FTL, you can still do interstellar travel just fine if you make people live longer, which is being worked on for other reasons already.

  It's not individual lifespans that are the issue, it's the lifespan of your equipment. If your rocket breaks down in the interstellar void, you have no resources with which to fix it. And then you need to be able to bootstrap the entire industrial base to build a new rocket at your destination without any help whatsoever aside from what you brought with you. Given the history of interoceanic colonization efforts on Earth, this suggests that the difficulty ranges from "insane" to "impossible."

    I think thats stil managable, even simply by redundancy and sending fleets of ships. Also 3D printing of replacement parts seems pretty promissing and is already being looked into (there is a basic 3D printer or the ISS).

      There is, but it doesn't really do anything, right? They printed some plastic toys with it; it's not operations-critical.
