Question

sls: common applications
use the information below to answer the question.
materials used
with sls, you can use multiple materials, which are suitable for functional
applications such as prototypes and actual production use. the materials are very
strong with high dimensional accuracy.

cost effectiveness
you can make low to medium production runs, which makes it very cost - effective.

complex geometries
being able to create a functional product with hollow sections that don’t require a
support structure is one of the main uses for sls technology. due to the powder bin
being the support, parts can be formed with hollow sections, such as a pipe. the ability
to do complex geometry along with no need for support material makes it a perfect
application for complex ducting creations.

which of the following is true about the cost of the sls
process?

it has an inefficient cost rate.

it has a high variability of cost.

it is very cost efficient.

it is the cheapest 3d printing process.

Explanation:

To determine the correct answer, we analyze each option against the "Cost Effectiveness" section of the SLS information:

• "It has an inefficient cost rate": The text says SLS is "very cost - effective", so this is false.
• "It has a high variability of cost": There is no information in the given text about cost variability, so we can't conclude this.
• "It is very cost efficient": The "Cost Effectiveness" section states "You can make low to medium production runs, which makes it very cost - effective", so this matches.
• "It is the cheapest 3D printing process": The text doesn't compare SLS's cost to other 3D printing processes, so we can't say it's the cheapest.

Answer:

It is very cost efficient.
