Question

bj: common applications use the information below to answer the question. jetting is used in several common applications. color sand print a common application of binder jetting (bj) is full - color sand prints. a sand print is useful for giving a realistic prototype of an idea. however, it is generally not functional as far as doing something mechanical. stress gradients binder jetting (bj) can also be used to identify stress gradients. the process allows the user to see where stresses might end up. the user can also see where a print might need more material or where to take the material away. large - scale sand mold another common application for binder jetting (bj) is sand molding. sand molding is less expensive, easy to do, and faster than the traditional method when done with binder jetting (bj). creating functional metal parts binder jetting (bj) also allows the user to create complex geometry and organic shapes. this can be used to create things such as automotive parts or golf clubs. in terms of sand prints, which of the following is binder jetting (bj) useful for? creating mechanically functional parts giving a realistic prototype of an idea large - run productions adding structure to secondary prints

Explanation:

The text states that a common application of Binder Jetting (BJ) in sand prints is to give a realistic prototype of an idea, and it is generally not useful for doing something mechanical like creating mechanically - functional parts. There is no mention of large - run productions or adding structure to secondary prints in the context of sand prints.

Answer:

giving a realistic prototype of an idea
