Someone needs to start working on homemade caps and primers.
You can’t print those, because they actually contain a little tiny bit of explosive, to set off the shockwave that ignites the powder.
You would have to have access to that type of explosive, or be able to make it and handle it safely, if you wanted to make your own primers, and good luck with that being legal for average joe citizens. Just stock up on what you can buy now, because they are probably cheaper than whatever you could build yourself anyway.

I don’t reccomend it unless you have a degree in chemical engineering.
A friend back in my highschool days blinded himself trying to make mercuric fulminate. We started out making rockets, but that wasn’t enough for him; he wanted a bigger bang, and he finally got it.
