this process i mentioned can be improved by using a machined wax pattern, and silicone mold material to make the mold. no release is needed, and the part will come out with amazing surface detail. better make that wax pattern right!
what i outlined is a fairly basic starting point to how prototype parts are fabricated many times. even whena big cnc or SLA machine is used to make the patterns, some engineers end up mixing resin, degassing bubbles, pouring, oven curing, etc.. whats nice is: a DIY type can get the same results at home with minimal fuss.
the drawback:thes echemicals are expensive!
