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 bed
being the support, parts can be formed with hollow sections, such as a pipe. the ability
for die complex geometries along with no need for support material makes it a perfect
application for complex ducting conditions.
what serves as the support during the sls process?
the build plate
the laser panel
the powder bin
the mechanical arms

Explanation:

In the "Complex Geometries" section of the SLS (Selective Laser Sintering) information, it states that "Due to the powder bed being the support, parts can be formed with hollow sections...". So we refer to this text to find the support during SLS.

Answer:

the powder bed
