In that case a mold is a smart move.

That was never an contention. Obviously if a mold is made, its possible it could be used to produce multiple child castings. My contention was that it was faster to print the object than the mold. Then us a casting material to make a mold from the printed object. There are a myriad of mold materials to choose from (sand, clay, ceramics, resins, etc) and they all have their plusses and minuses as well as optimum use as far as what the casting material will be (melted plastic, metal, resins, etc).
