Question

technology summary table
use the information below to answer the question.
below is a section of the technology summary table covering binder jetting (bj).
using the table on the left, what is a weakness of the binder
jetting (bj) process?
it has a very high cost.
it has a small build volume.
its mechanical properties are not as good as powder bed processes.
it cannot create metal or sand parts that have good functionality.

Explanation:

Looking at the "Strength/Weakness" section of the Binder Jetting (BJ) in the table. The first three points (-Low cost, -Large build volumes, -Functional metal parts) are strengths. The last point (-Mechanical properties not as good as Powder Bed) is a weakness. Checking the options:

• "It has a very high cost" is wrong as the table says low - cost.
• "It has a small build volume" is wrong as the table says large build volumes.
• "Its mechanical properties are not as good as Powder Bed processes" matches the weakness in the table.
• "It cannot create metal or sand parts that have good functionality" is wrong as the table says it can create functional metal parts.

Answer:

Its mechanical properties are not as good as Powder Bed processes.
