Question

bj: materials and dimensional accuracy. use the information below to answer the question. for a full - color sand print, binder jetting (bj) is very dimensionally stable. it is about 100 microns. for a mold or core, it can vary between 140 and 180 microns, which is still very small. with metal, there is a 50 - micron tolerance because there is no heat in the printing process. however, this can change when adding bronze to the piece, because it has to be heated in an oven or furnace. there can be up to a 2% change in shrinkage on the dimensional accuracy, so it is a little bit unpredictable. materials: sandstone, soft, full - color, low density. stainless steel, optimal binder addition, can be sandblasted, corrosion - resistant. what type of binder jetting (bj) material has aerospace and automotive applications, is temperature resistant, and has high chemical resistance? tungsten carbide, silica sand, inconel alloy, sandstone

Explanation:

Inconel alloy is known for its use in aerospace and automotive applications due to its high - temperature resistance and high chemical resistance properties. Tungsten carbide is mainly used for its hardness in cutting tools etc., silica sand and sandstone do not have such high - performance characteristics for these high - end applications.

Answer:

Inconel alloy
