I laughed, and I apologize. But of all the components you listed, the "ink" would be the most expensive. Consider what your 3D printer would have to do:
1 - Print a container (an empty cartridge)
2 - Position itself over the empty cartridge it just printed
3 - Drain its cartridge, filling the cartridge it just printed (but not managing to fill it all the way).
4 - Wait for you to refill it with more ink.
5 - Finish filling the cartridge it printed earlier.
