Question

mj: dimensional accuracy
use the information below to answer the question
other than the initial heating of the resin before it goes to the print head, there is no heat involved with material jetting (mj). this reduces the possibility of warpage or shrinkage at the print. because there is no temperature gradient change, mj is a stable, accurate printing process.
however, there is the possibility of shrinkage because when the part cures with uv light, there is an amount that will be reduced in size. that effect can be compounded with larger pieces.
accuracy
because of the support material used in this process, there is a very high degree of dimensional accuracy. with mj, there is a tolerance of.01 millimeters, as compared with sla, which has a tolerance of 0.15 millimeters. sls has a tolerance of 0.1 millimeters, and fff 0.5
what to avoid
too much exposure to ultraviolet light could have a detrimental effect. high humidity can also affect the print, as can high heat. with mj, avoid exposure to sunlight, ambient heat, or humidity, which can cause changes in dimensional accuracy and might cause some warping.
why is there a high degree of dimensional accuracy for material jetting (mj)?
the build plate shape
the amount of resin used
the advanced slicing software
the support material used

Explanation:

The text states that due to the support material used in Material Jetting (MJ), there is a very high degree of dimensional accuracy.

Answer:

the support material used
