bj: post - processing\nuse the information below to answer the question.\nwith binder jetting, many of the post - processing procedures are done at the facility that did the printing.\nthe first thing that happens after printing is that the print must remain in the powder bed so that it hardens. once it is taken out of the bed, the excess powder is removed with a high - pressure air blast.\nsand\nif the object is a full - color sand print, the process is complete when the excess powder is removed. however, a dye can still be added for additional color. an infiltration process can also be added to the post processing to add more mechanical structure to the print. this is done by adding a clear coat to the print which can help it feel smoother and protect it. when a sand print is to be used as a mold, there are secondary burn - outs to give it a better binding as well.\nmetals\nsintering is a requirement for metal parts. this sintering is done with the use of an oven for binder jetting (bj) metal parts. once this has been done, the process is complete. the pieces can be post - processed with a bronze infiltration to give it better mechanical properties.\nwhat does an infiltration process add to binder jetting (bj) sand prints?\nheat resistance\na more geometric shape\nadditional color\na more mechanical structure
