Optimal growth condition for cell growth

Hi, I am trying to write a scifi novel.  A mad scientist is trying to create a fully synthetic self replicating cell that ultimately divides into full grown human.  In my story, a quantum computer power enables him full atom level scanning of a human zygote.  He also builds a self assembler machine that "prints" a new human zygote cell with a special material.

What I am not sure of is the environment the cell must have in order for it to go through the growth cycle.  In human 'real' biology, I assume a zygote must derive energy from the fluid that it is suspended in.  Am I right?  I mean, in order for the cell to build the proteins and organelles, it needs to consume some kind of energy from its environment, right?  In my fantasy story, for the artificial zygote to grow, it will need to extract some energy from its environment.  Am I correct so far?

Is my reasoning any where near realistic?  I mean in the realm of a sci-fi story.  Any feedback would be appreciated.
