With FDM ("plastic glue gun") printers, this process typically
involves a program called a "slicer". You export the model from the 3D
modeling program (.amf, .wmf and .stl are the most common formats) and
input that into the slicer program, which "slices" the model into
layers, and outputs commands to the printer (commonly G-code) into a
text file. The text file is then transported to the printer (via
network, or modern sneakernet aka SDcard) where you load it and start
the printing process.

Common slicer programs are Cura

In general, it is easier to start with the slicer program recommended
/ supplied by the 3D printer manufacturer - they have taken the
guesswork out of the settings, which gives you better printing results
from the start.

If I have to choose between Cura and PrusaSlicer, I prefer PrusaSlicer
because it has an easier user interface.
