Question

psf: benefits and limitations
use the information below to answer the question.
powder bed fusion (pbf) is not necessarily the best process to use for everything that is made of metal. it may be more cost-effective to make your piece in the traditional method.
benefits
the parts are dense.
its great to use for pieces that require complex geometry.
it is efficient.
limitations
the machines have a large foot and are very expensive.
if there is overall build bed, you may need to create the piece in two parts and combine it at a later time.
it requires a lot of post-processing at the operator level: grinding off the support
when there is a need for post-processing, what is one limitation of powder bed fusion (pbf) that must be done?

• adding an adhesive layer to the surface
• grinding off the support structure
• storing the plastics in cool temperatures
• curing the plastics slowly

Explanation:

Powder Bed Fusion (PBF) is a 3D printing technology. In post - processing for PBF, support structures are often used during the printing process to hold up overhanging parts of the object. After printing, these support structures need to be removed. Grinding off the support structure is a common post - processing step. Adding an adhesive layer is not a typical post - processing limitation for PBF. Storing the prints in cool temperatures is more of a storage consideration rather than a post - processing limitation. Curing the prints slowly is not a key post - processing limitation for PBF compared to the removal of support structures.

Answer:

grinding off the support structure
