Question

sls: common applications
use the information below to answer the question.
what serves as the support during the sls process?
text about sls: can use multiple materials, suitable for functional (e.g., prototypes, production use), high dimensional accuracy; cost-effectiveness (low to medium production runs); geometries (create functional product with hollow sections, no support needed, powder bin support, complex geometry, no support material, perfect for complex ducting creations)
options: the build plate, the laser panel, the powder bin, the mechanical arms

Explanation:

From the text, under "geometries", it says "Due to the powder bin support, parts can be formed...". So the powder bin serves as support.

Answer:

the powder bin
