Question

bj: post - processing. use the information below to answer the question. in 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 look smoother and protect it. when a sand print is to be used as a mold, there are secondary heat treatments to give it a stronger binding as well. metals: sintering is a technique 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 process can be continued with a bronze infiltration to give it better mechanical properties. where are many of the post - processing procedures done for binder jetting (bj) prints?

Explanation:

The text states "Binder Jetting, many of the post - processing procedures are done at the facility that did the printing".

Answer:

the facility that did the printing
