Default Best way to make many identical sculptures?

Hi, I am new in craftsmanship. Could someone help me by recommending me the best way to make many plaster sculptures of the same model?? I am not talking about mass production, but almost. Something similar to plaster/fiberglass molds, which I could use many times to make the same model. Now I guess for more "complicated" such as this one it won't be so easy by using molds, as when trying to get the sculpture out it would have to be either by pieces or breaking the mold.. So any ideas such as cutting out of a plaster block, 3D printing, make as many molds as needed for a sculpture, make foam parts out of it, then join the foam. Afterwards insert the foam in alginate, burn the foam inside, pour plaster and release the sculpture (very long, it was an idea I had which I am not sure if it could work, Im new as I said).
I am looking for a cheap, relatively easy and quick way. Thanks for any help!!

You could make 3D printed molds I guess. How big is this exactly?

I know you are showing an example there above but what size are you aiming to make?

You could make a silicone mold in multiple pieces. Use clips to hold the pieces of the mold together, pour your mold, when it is dry remove the clips and the pieces of the mold should come away just fine. You could "divide" your mold into as many pieces as needed. The silicone would be stiff enough to hold, especially if you support it with rope or string around when it is fastened together, but flexible enough to peel off fairly easily. I have seen instructions online for how to make multiple piece molds, so it shouldn't be too hard.
