Question

pbf: dimensional accuracy
use the information below to answer the question.
the tolerances of direct metal laser sintering are very good. they are the same as material jetting with a size of 0.1 millimeters - just below that of a human hair.
once the print is complete, the supports need to be cut off the print bed by the operator. once the user has the piece, they can do any processes to it that they would with any other metal material.
materials
stainless steel is corrosion - resistant and the most cost - effective.
bronze is functional but quite expensive.
aluminum is a good material but expensive.
titanium is another good material but expensive.
other available materials include:

• cobalt - chrome
• inconel metal
• nickel - chrome (alloy)

in terms of powder bed fusion (pbf), which of the following is true about stainless steel?
it has an issue with corrosion.
it is not compatible with the process.
it is very expensive.
it is the most cost - effective material.

Explanation:

The text states that "Stainless Steel is corrosion - resistant and the most cost - effective." So, we check each option:

• The first option "It has an issue with corrosion" is wrong as it is corrosion - resistant.
• The second option "It is not compatible with the process" is not mentioned in the text.
• The third option "It is very expensive" is wrong as it is the most cost - effective.
• The fourth option "It is the most cost - effective material" is correct as per the text.

Answer:

It is the most cost - effective material.
