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 hose.\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 strength to the print. this is done by adding a clear coat to the print which can help it last longer and protect it. when a sand print is to be used as a mold there are secondary heat treatments to give it a better binding as well.\nin post - processing, what can be done to add additional color to binder jetting (bj) sand prints?\na dye can be added.\na metal can be introduced\nan infiltration process can be done\na secondary heat treatment can be used
