So far organs have proven to be too complicated to be easily printed let alone made artificially entirely. The only internal organ we even stand a chance at right now is the heart. The heart is surprisingly easy as it's just a sack of muscles, with blood vessels running around it. All the other organs are far too intricate and finely structured.

Looking into the future I would say, that organs grown from your own DNA in Zero G in orbit would be our best bet. A lot of things have to happen to make this affordable.

And the liver. A lot of the functions of the liver are done on a cell by cell basis. So a big glob of cells will do at least some of the work. But it isn't a full liver replacement.
