The volume of Planet Earth is 108.321x10^10 km3.. Converted to std meters, that is 1.08321x10^21 m3.
A typical high flow 3d printer hotend (without getting insane) can hit around 25mm3/sec volumetric flow assuming no nozzle or acceleration restrictions. Converted to std meters, that is 2.5x10^-8 m3/sec.
If you ran that hotend continuously with no breaks, it would only take about 4.332x10^28 seconds to print the planet Earth... or 1.374x10^21 (1.4 sextillion!) years!
Gentlemen. We're going to need a bigger printer.
