Question

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. sand. 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 strength to the print. this is done by adding a clear coat to the print which can help it hold together 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. metals. sintering is a common process for metal prints. this sintering is done with the use of an oven for binder jetting bj metal prints. once this has been done, the process is complete. the prints can be enhanced with a bronze infiltration to give it better mechanical properties. what can be done to a binder jetting (bj) metal print to give it better mechanical properties? an ultrasonic bath a chemical wash a bronze infiltration adding a clear coat

Explanation:

The text mentions that for Binder Jetting (BJ) metal prints, bronze infiltration can be added to give it better mechanical properties. Other options like ultrasonic bath, chemical wash, and adding a clear - coat are not specifically stated to enhance mechanical properties for metal prints in the provided text.

Answer:

a bronze infiltration
