i want to make a mold i can pour plastic into, what do i use?
im thinking i'll have to make a prototype of the part with something like clay, after its been baked, of course. then what can i use to make the mold? ive seen plastic pellets you mix with water and it makes well, plastic that you can pour, and i was thinking i should use that for the final product.
but what should the mold be made of? it would need to be easy to get the part out of it, but it cant be too easy or else it might not set right.
