Question

metal powder bed fusion vs. binder jetting
use the information below to answer the question.
binder jetting uses a binding agent to glue the particles together. it does not use any
heat in the bin. once the form is removed from the bin, it is placed in an oven to
complete the process. binder jetting is less expensive than metal powder bed fusion,
and the pieces can be much larger.
in contrast, metal powder bed fusion uses heat to fuse metal powder together, but
does not require heat for post - processing. there is also a difference in quality and
mechanical property. metal powder bed fusion has excellent tolerances, dimensional
accuracy, and good mechanical properties. binder jetting has a limited range of
mechanical properties for functional purposes.
toleration

• metal powder bed fusion: 0.3 mm
• binder jetting: 0.3 mm

if a user is building a highly fine - tuned, complex system like an engine, metal powder
bed fusion would be the way to go. binder jetting is functional for less finely tuned
forms, such as handles, door knobs, or golf clubs.
in terms of mechanical properties, which of the following is
true about metal powder bed fusion?
metal powder bed fusion has good mechanical properties.
metal powder bed fusion has limited mechanical properties.
metal powder bed fusion does not have any mechanical properties.
metal powder bed fusion has worse mechanical properties than binder
jetting

Explanation:

The text states that Metal Powder Bed Fusion has excellent tolerances, dimensional accuracy, and good mechanical properties. Binder Jetting has a limited range of mechanical properties for functional purposes. So, Metal Powder Bed Fusion has good mechanical properties.

Answer:

Metal Powder Bed Fusion has good mechanical properties.
