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 fdm 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. the support structure for material jetting (mj) is what? magnetic; dissolvable; tree - shaped; recyclable

Explanation:

The text clearly states that with Material Jetting (MJ), one of the materials printed is a dissolvable support material. It also mentions that the support structures are dissolvable and are put in an ultrasonic bath to break them down.

Answer:

dissolvable
