Does 3d printing end up economical to produce shit instead of having it printed by someone else?
Not if you need to only have a couple things made per year. But if you like to tinker and you like fixing and making stuff then it's the best hobby you could get into. I love it.
This largely depends on what you print. If you print toys and trinkets, not really. If you print things you would buy otherwise, then that is money saved and it eventually adds up to the printer, learning time, and filament.
But if you want a one off, yeah having it printed and ordered is an easy way to go, several places offer that service.
