Question

materials and dimensional accuracy. use the information below to answer the question. in binder - jet 3d print, binder jetting (bj) is very dimensionally stable. it is about mold or core, it can vary between 240 and 380 microns, which is a 50 - micron tolerance because there is no heat in the printing. however, this can change when adding bronze to the piece, because it has to be sintered in an oven or furnace. there can be up to a 2% change in shrinkage on the accuracy, so it is a little bit unpredictable. what can change the tolerance of a binder jetting (bj) print made with metal? using tungsten carbide; using stainless steel; using no support structure; adding bronze to the piece

Explanation:

The text mentions that adding bronze to the piece can change the tolerance because it requires heating in an oven or furnace and can cause up - to a 2% change in shrinkage.

Answer:

adding bronze to the piece
