Will we ever reach immortality?

Or will science evolve ever to be able to keep ones conscious alive for much longer than a current average life span?

Some will argue that we are able to achieve:
 3-D Printing body parts (to replace faulty / dying ones)

Freeze bodies/brains (To bring back at a later date when possible, similar to what Walt Disney is currently in)

Digitally construct ones self / brain.

I’ve developed a major fear of death and the idea of the infinity of time after death, and this has given me a bit of hope, I should have easily another 50-60 of years of life left, and many experts claim within the next near decades, we will be able to achieve incredible things.

I am curious to what you guys think of this idea? Is it possible? Can it work?
