the prototype was 3D printed out of an ABS-type plastic/resin material...not exactly sure what it is. all the copies will be resin and thus cheaper. it's not necessarily about the cost being spread between a few people; the model making process is usually the cost of parts & labor for the builder, plus materials for casting. in the case of this model, i am selling the master copy to a producer
and thanks for all the compliments! i'll continue to do what i can!!!
