Question

binder jetting: metal use the information below to answer the question. the 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. 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 print will be in a solid form, but the process is still not fully complete. at this point, the print is sanded down. this is when the binding agent solidifies, but the metal has not been melted together. the next of the process includes the print being put into an oven to be sintered and fused together. after the print is removed from the oven, some shrinkage and internal stress can occur on fine - detail parts. after the final sintering process, the print is removed from the oven and cooled. at this point, the print will be ready to be used as a functional piece and the surface will have a grainy feel. however, this may be remedied with additional treatment. if the goal is to build a functional application, a bronze material will be poured into the part. this will fill in any open spots of the part, creating a part with a higher density of metals. in the binder jetting process, why do printed parts need to be placed into an oven after they have been formed? to cure colored dye that has been painted onto the surface of the prints to prevent printed parts from shrinking and warping to melt the printed materials together

Explanation:

In Binder Jetting, after the part is formed, the metal particles have not been fully fused together. Placing the printed part in an oven melts the printed materials (usually metal powders and binders) together to create a more functional and solid - state part. There is no mention of colored dye painting in the context, and while shrinkage can occur, the main purpose of the oven step is melting to fuse materials.

Answer:

to melt the printed materials together
