benefits

• one of the big benefits of bj printing is that it doesnt use any heat during the printing process. heat causes internal stresses in the print, which can cause failure, warping, or shrinkage.
• the second need is the process is inexpensive.
• there is a lack of necessary post - processing.
• binder jetting (bj) has a larger print area than other processes.
• compared to other technologies for metal printing, binder jetting (bj) is less expensive.
• binder jetting (bj) is the largest choice for online printing.

• the process is slow.
• there is limited material availability.
• the texture is grainy, but the finish can be polished.

they can be polished.
they can be metal plated.
they can be sintered in an oven.
they can go through a secondary heat treatment.

Explanation:

Binder jetting prints have a grainy texture but can be polished to make it less grainy as stated in the limitations section. Metal - plating, sintering in an oven, or secondary heat treatment are not mentioned as solutions for reducing grainy texture.

Answer:

They can be polished.
