Question

binder jetting: metal
use the information below to answer the question.
the metal and sand materials used in the binder jetting process are very similar. the most commonly used metal is a stainless - steel powder. this powder material is best used for prototypes and aesthetic pieces.
the other metal material that is available is a stainless - steel metal combined with a bronze infiltrant. in this process, the bronze material is used to fill in the porous spaces throughout the part and will create a more functional part.
after the printer has finished creating the form and the metal part is taken out of the powder bed, the part will be a solid form, but the process is still not fully complete. at this point, the part is in the green state. this is when the binding agent solidifies, but the material has not been sintered together. the rest of the process includes the part being put into a furnace to be sintered and melted together.
after the part is removed from the oven, some shrinkage and internal stress can occur on low - density parts.
after the heat - treating process, the part is removed from the oven and cooled. at this point, the part will be too porous to be used as a functional piece and the surface will have a grainy feel. therefore, this part can be remedied with an additional treatment.
if the part needs to be hip (hot isostatic pressing), a bronze material will be poured into the part. this will fill any pores and create a part coating with a better surface finish.
in the binder jetting process, what form will the printed resin be in after the part has finished printing?
a hard form
a soft form
a liquid form

Explanation:

The text mentions that after the part has finished printing in the Binder Jetting process, the binder agent solidifies, and the part will be in a solid form which is a hard form.

Answer:

a hard form
