binder jetting: metal\nuse the information below to answer the question.\nthe metal and sand material 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.\nthe other metal material that is available is a stainless - steel metal combined with a bronze infiltration. in this process, the bronze material is used to fill in the porous spaces throughout the print and will create a more functional part.\nafter the printer has finished creating the form and the metal part is taken out of the powder bin, the print will be in a solid form, but the process is still not fully complete. at this point, the part is in the green form. this is when the binding agent solidifies, but the metal has not been melted together. the rest of the process includes the print being put into an oven to be sintered and melted together.\nafter the print is removed from the oven, some shrinkage and internal stress can occur on fine - thin pieces.\nafter the final sintering process, the part is removed from the oven and cooled. at this point, the print will be too porous to be used as a functional piece and the surface will have a grainy feel. however, this issue can be remedied with an additional treatment.\nif the print needs to fulfill a functional application, a bronze material will be poured into the part. this will fill in the porous spaces of the part, creating a part with a hybrid combination of metals.\nwhen would a bronze material be used in the binder jetting process?\nits use is limited to situations where a two - toned color effect is desired.\nit is only used when needing to make a print smooth and shiny.\nit can be used to fill in the porous areas of a printed part.
