Question

support structures
use the information below to answer the question.
need
a support structure is not needed with powder - based printing, such as sls sand or
polymer. however, with metal printing, a support will be needed to control the
warpage and to dissipate heat into the build plate.
most slicing programs for fused filament fabrication (fff) will have an option to
automatically add support. support can also be added manually to any spot that needs
more.
with sla, the considerations differ depending on whether the printer is a bottom - up
or top - down machine. there are also choices as to how the support material is
created.
removal
a support structure can be removed by sanding, vapor smoothing (with abs filament),
or using a grinder for direct metal laser sintering (dmls).
fff and material jetting can use dissolvable support structures as well. an fff
machine will need two spools - one for the build material and one for the support
material. with material jetting, there will be two bins. with fff, there are different
ways the filament can be dissolved, depending on the type of filament. one uses a
chemical process; the other uses water, which is probably safer.
most slicing programs for fused filament fabrication (fff)
have an option to do what?
dissolve support structures
automatically add support
split prints into quarter sections
design prints that do not require support

Explanation:

The text states "Most slicing programs for Fused Filament Fabrication (FFF) will have an option to automatically add support".

Answer:

automatically add support
