bj: post - processing. use the information below to answer the question. with binder jetting, many of the post - processing procedures are done at the facility that did the printing. the 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. if 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 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. what can be used for better binding when a binder jetting (bj) print is going to be used for a mold? an infiltration process; secondary heat treatments; electroplating; a clear coat
