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, theres a 30 - 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 - stiff - full color - low distortion. stainless steel - optional bronze additive - can be post - processed - corrosion resistant. inconel alloy. what percentage change in shrinkage can be caused by adding bronze to a binder jetting (bj) print? 15% 11% 5% 2%
