Ja.  The closest thing I saw to a plausible round trip mission was Robert
Zubrin's Mars Direct approach, which does a lot of this.  It proposes
soft-landing with a vehicle, then setting up a facility using indigenous
materials and manufacturing the fuel for a return flight from these
materials.  Interesting, but I couldn't convince myself that the reliability
model closes.  If I signed up for such a mission, I would try like hell to
make it work, but would quietly treat it as a one way trip, go thru the
stages of grief for losing myself before I ever left home.

I am seeing this 3D printing technology taking off however.  I can vaguely
imagine landing some 3D printers on Mars, making the factory with that, then
having a return rocket mostly assembled before the humans arrive.  Another
likely scenario has humans inserted into Mars synchronous orbit, never
landing on the surface, but staying there a couple years to operate
semi-autonomous equipment on the ground.
