Questions And CORRECT Answers
What is an advantage associated with binder jetting? - CORRECT ANSWER - Support
materials are unnecessary.
Which of the following is a disadvantage of using melting powder bed fusion (PBF) processes?
Compared to sintering PBF processes, melting PBF processes make parts that: - CORRECT
ANSWER - Have poorer tolerances and surface finishes.
What is an advantage associated with vat photopolymerization? Vat photopolymerization
