Question

mj: support structures
use the information below to answer the question.
with material jetting (mj), there is the capability of having two materials printed at
the same time: one being the build material; the other being a dissolvable support
material. it shares some similarities to the fused filament fabrication process that
utilizes a dual print head.
print heads
the print heads for the build material and the support structure can run concurrently.
this would be dictated by the slicing software to make sure they dont cross. the
slicing software determines if there would be a conflict over the build plate. it might
temporarily discontinue printing with one head and continue with the other to ensure
that they do not run over each other in the printing process.
structure form
another aspect of material jetting (mj) is the form the structure takes. it is one solid
form coming up vs. a created lattice, which would use less material such as that used
by fff or sla.
removing the support structure
the support structures are dissolvable. the form is put in an ultrasonic bath to help
loosen and break down the support structure. the ultrasonic bath has a high amount
of energy that can break down the structure so there is less opportunity for damaging
the surface. there is minimal surface imperfection. it has a high - detail finish, which
makes it good for cast jewelry making. with the ability to print two materials at once,
mj is a good solution if you need minimal surface damage on your forms.
what might the slicing software do to ensure that printer
heads do not run over each other in the material jetting
(mj) process?
attach the printer heads to each other
discontinue one printer head and continue with the other
speed up the material printer head
choose to not use the support material

Explanation:

The text clearly states that the slicing software might temporarily discontinue printing with one head and continue with the other to ensure printer heads do not run over each other.

Answer:

discontinue one printer head and continue with the other
