Question

pbf: benefits and limitations
use the information below to answer the question.
direct metal laser sintering 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 prints are dense.
• it is good to use for projects that require complex geometry.
• it is organic.

limitations

• the machine has a large size and is very expensive.
• it has a small build bed. you may need to create the piece in two parts and combine it in post - processing.
• it requires a lot of post - processing at the operator level - grinding off the support structure, removing the powder, etc.

powder bed fusion (pbf) is good for projects that require which of the following?
low heat
large print beds
limited post - processing
complex geometry

Explanation:

The text mentions that PBF (Powder Bed Fusion) is good for projects that require complex geometry as one of its benefits. The other options (low heat, large print beds, limited post - processing) are either not mentioned as benefits or are actually limitations (e.g., small build bed which is the opposite of large print beds, and a lot of post - processing is a limitation, so limited post - processing is incorrect).

Answer:

complex geometry
