By default, i3 ignores the Print Screen key available in most keyboards. How can it be activated?

Everything inside i3 needs to be bound and just a minimal set of keys is added/generated inside the default config. Some keys that are not letters can be represented with its keycodes or keysyms. More about this subject here:
Printscreen is the Print keysym.
I personally use gnome-screenshot to that task, since it can crop images, making life easier. Add the following lines to your .config/i3/config or any config file you are using as the i3wm main config file.
#interactive screenshot by pressing printscreen
bindsym Print exec gnome-screenshot -i
#crop-area screenshot by pressing Mod + printscreen
bindsym $mod+Print exec gnome-screenshot -a
Some people like to use scrot. That is up to you to decide :) . Example:
bindsym Print exec scrot $HOME/Images/`date +%Y-%m-%d_%H:%M:%S`.png

1The second binding with
Mod1+Printdoes not work, but the rest is more than enough. Jan 31, 2019 at 14:51 -

@LuísdeSousa
Mod1is alt, not your main mod key(Control or Winkey, whatever you have set up). Editing the answer to use mainmodkey. Sorry for the misinformation from myi3/config– user34720Jan 31, 2019 at 18:07 -
@ndwildner This is not related to the
$mod, there is even a sort of error sound that is played. Jan 31, 2019 at 19:32
To expand on @user34720's answer, if bindsym $mod+Print exec gnome-screenshot -a doesn't work, pass the --release parameter to bindsym
bindsym --release Print exec gnome-screenshot -i
bindsym --release $mod+Print exec gnome-screenshot -a
