i got a vital question in order to properly give you a assessment i need to know the below (you can do it in a private message if you like wether of its me or not)

Desnity is equal to
Mass divided by volume a common metric example is grams per ml , then it order to get a idea from there if i know the prints total volume
However despite these restriction you are probbly trying to think of the infill which is the percentage of material
Property differences such as durablity , and its fluid machanics and lots of other things including the density as well as thickness
But in my positon what material would he approprate
for example for example a slingshot would be a different need than lets say a longbow.
I respect the beginners but i just wanted to give you the calculation source in order to give you a proper awnser
