Test for Z-axis shrinkage compensation
Print test directly from platform and without supports.
After printing wash the test, dry and cure it according to the resin manufacturer recommendations
Measure steps high using depth gauge. (Usually integrated into caliper)
Calculate shrinking coefficient
50/M*100%=S
50 - step high in stl (you may also use 40;30;20;10 mm)
M -measured high of step
S - shrinkage coefficient for Z axis
Most often there are no problems with shrinkage along the Z axis, since the size depends on the printer transmission. The test is most often used to confirm that there are no problems with this axis
