Question

bj: materials and dimensional accuracy. use the information below to answer the question. dimensional accuracy. 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 240 and 380 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 3% change in shrinkage on the dimensional accuracy, so it is a little bit unpredictable. materials. sandstone. full color. low density. stainless steel. high strength. inconel alloy. what type of binder jetting (bj) material has a high strength - to - weight ratio, is very strong, and is hard? tungsten carbide sandstone inconel alloy stainless steel

Explanation:

Tungsten - carbide is known for its high strength - to - weight ratio, high strength, and hardness. Sandstone is a sedimentary rock and not typically characterized by high strength - to - weight ratio like metals. Inconel alloy and stainless steel are strong materials but not as well - known for the extreme strength - to - weight ratio and hardness as tungsten - carbide.

Answer:

tungsten carbide
