Question

metal powder bed fusion vs. binder jetting
use the information below to answer she question.
binder jetting uses a binding agent to glue the particles together. it does not use any heat in the die. once the form is removed from the die, it is placed in an oven to complete the process. binder jetting is less expensive than metal powder bed fusion, and the parts can be much larger.
metal powder bed fusion uses heat to fuse metal powder together. not often will require heat for post processing. there is also a difference in quality and mechanical properties. metal powder bed fusion has excellent tolerances, dimensional accuracy, and good mechanical properties. binder jetting has a limited range of mechanical properties due to thermal properties.
tallest part:

• metal powder bed fusion: 2.7 feet
• binder jetting: 6.7 feet

if you are building a highly stressed engine system like an engine, metal powder bed fusion would be the way to go. binder jetting is best for the less stress - related aspects, highly or variable shapes, or low - cost parts.
which of the following processes uses a binding agent to glue the particles together?
metal powder bed fusion
binder jetting
material jetting
fused deposited fabrication

Explanation:

The text clearly states that "Binder Jetting uses a binding agent to glue the particles together."

Answer:

Binder Jetting
