Model Makers in Zamil Ladders refer to those craftsmen who help in creating a three dimensional copy of any design or concept to aid the manufacturing process of an object. Since most objects that we use today, need a mock up from which to create them, model makers are responsible for creating a prototype of that object in order to understand it general shape and size as well as usability. Model makers are highly skilled craftsmen who have been known to use both their own hands as well as various machines to shapes these models. Two of the processes that are basic to model making are additive and subtractive.
