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 of 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 0.3 millimeters, and fdm is 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, and excess heat, or humidity, which can cause changes in dimensional accuracy and might cause some warpage. when is there a possibility for shrinkage during the material jetting (mj) process? when the print cures with uv light when the support structure is dissolved when the last layer is completed on the print when the first layer is created on the build plate

Explanation:

The text states that there is a possibility of shrinkage when the part cures with UV light in the Material Jetting (MJ) process as there is a volume that will be reduced in size.

Answer:

when the print cures with UV light
