Question

metal powder bed fuslon 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.
tolerances

• metal powder bed fusion - 0.3 mm
• binder jetting - 0.1 mm

if a user is developing 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
systems, such as jewelry, small knobs, or golf clubs.
which of the following processes is best suited to create a
highly fine - tuned, complex system like an engine?
material jetting
stereolithography
binder jetting
metal powder bed fusion

Explanation:

The text states that Metal Powder Bed Fusion has excellent tolerances, dimensional accuracy, and good mechanical properties. A highly fine - tuned, complex system like an engine requires high precision and good mechanical performance. Binder Jetting has limited mechanical properties for functional purposes. Material Jetting and Stereolithography are not mentioned in the text in the context of metal - based processes for such complex mechanical systems.

Answer:

Metal Powder Bed Fusion
