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.
why is the sls process very cost-efficient?
the materials for the sls process are 100% reusable.
the process does not have energy consumption costs.
large-scale applications can be made.
low to medium production runs can be made.

Explanation:

To determine why the SLS process is cost - efficient, we refer to the "Cost Effectiveness" section of the given information. It clearly states that "You can make low to medium production runs, which makes it very cost - effective." Now let's analyze the other options:

• The option "The materials for the SLS process are 100% reusable" is not mentioned in the text as a reason for cost - efficiency.
• The option "The process does not have energy consumption costs" is also not stated in the provided information.
• The option "Large - scale applications can be made" is not related to the cost - efficiency of the SLS process as per the given text.

Answer:

Low to medium production runs can be made.
