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 conditions.
which of the following are sls materials suitable for?
circuit boards
large scale applications
furniture
prototypes

Explanation:

From the "Materials Used" section, it says SLS materials are suitable for functional applications such as prototypes and actual production use. Among the options, "prototypes" is explicitly mentioned as a suitable application. For "circuit boards", there's no info suggesting SLS is for that. "Large - scale applications" is not supported as it says low to medium production runs. "Furniture" isn't mentioned as a suitable use.

Answer:

prototypes
