There are some major differences in settings depending on the size of the printer and which type of
LCD screen it is using (Color vs Mono):
Normal Exposure Time - The General rule of thumb is that mono screens require approximately
⅓
to
¼
of color screens’ values. The exact time will vary based on the resin being used.
Bottom Exposure Time - Another general rule is that the mono screen value is usually about ½ of
color screens. Again exact time will vary based on resin being used.
Bottom Lift Distance - Larger printers require higher lifting distances
Lifting Distance - Larger printers requires higher lifting distances
Some settings can be adjusted to increase the speed of a print. These settings require experimentation
on the end user to adjust to reliable settings and also have consequences if not carefully monitored:
Layer Height - Increasing the layer height will lower the overall amount of time needed to print. The
consequence will be some increased exposure times. For example at 0.1mm vs 0.05mm, you would
essentially cut the print time in half. How much to increase exposure time depends on the resin. Printing
at 0.1mm instead of 0.05 does not mean to double the exposure time.
Lifting Speed - Increasing this will speed up how fast the build plate lifts the print off of the film.
WARNING:
Going too fast could result in failed prints or torn film meaning wasted resin and potential
damage to the screen/machine. Do not increase too much. This is a setting that you progressively
increase the more comfortable you feel with the print job being able to handle the speed.
Retract Speed - Increasing this will speed up the build plate lowering back down after lifting.
WARNING:
Going too fast could result in prints prematurely lowering before resin fills in gaps in the vat.
This will result in missing layers and potentially broken or failed prints. This is a setting that you
progressively increase the more comfortable you feel with the print job being able to handle the speed.
Lifting Distance/ Bottom Lift Distance: The Larger the printer means that values increase. The preset
values we have on our website, and in ChiTuBox can be decreased depending on the print job and
layer height to save a little extra time. It won’t save much though, and can be a bit harder to get right.
WARNING:
Lowering too far can result in the print not fully peeling off of the film. Can result in missing
layers, failed prints, and broken nFEP in special cases.
