3.3 Resin Parameter (See Picture 14)
Resin Density: 1.1g/ml
Resin Cost: You can input the real price of the resin you purchased, and the slicing software can
calculate the resin costs for each model you print.
3.4 Parameters (See Picture 14)
Layer Height: The thickness of each printed layer, the recommended height is 0.05mm, but you
can set it from 0.01-0.2mm. The higher thickness you set, the longer time it will take for exposure
of each layer.
Bottom Layer Count:The setting number of initial printing layers. If the number of bottom layers
is n, the exposure time of the first n layers is the exposure time of the bottom layer, the default
setting is 2.
Exposure Time: The exposure time for normal printing layers. The default exposure time is 2.5
seconds, and the thicker the printing layer setting is, the longer time it will take.
Transition Layers: The number of transition layers after the bottom layer to make it stickier
between layers. Except for the exposure time, other parameters of the transition layer are the
same as the normal layer.
Bottom Exposure Time: The setting of bottom layer exposure time. Properly increasing the bottom
layer exposure time can help to increase the stickiness between the printing model and the build
platform; the default setting is 32 seconds. The longer the setting time, the stickier the bottom
layer will be on the build platform.
Wait After Lift: After printing platform is lifted, the time difference between the printing platform
starts to stationary and starts to return, the default setting is 0 seconds.
Wait Before Cure: After the build platform moves to the printing surface, the time difference
between the build platform starting to stationary and starting to exposure, the default setting is
0.5 seconds.
Wait After Cure: The time difference between the end of the exposure and the start of the build
platform to leave the printing surface, the default setting is 0 seconds.
Software Installation and Setup

Bottom Wait After Lift: When printing the bottom layer, the time difference between the build
platform starting stationary and starting to return to the printing surface after lifting, the default
setting is 0 seconds.
Bottom Wait Before Cure: When printing the bottom layer, after the build platform moves to the
printing surface, the time difference between the build platform starting stationary and the start
of exposure, the default setting is 0.5 seconds.
Bottom Wait After Cure: When printing the bottom layer, the time difference between the end of
the print exposure and the start of the build platform to leave the printing surface, the default
setting is 0 seconds.
Bottom Lift Distance: During the bottom printing process, the distance that the build platform
leaves the printing surface each time, the default setting is 2+3mm.
Lifting Distance: In the normal layer printing process, the distance that the build platform leaves
the printing surface each time, the default setting is 2+3mm.
Bottom Retract Distance: During the bottom printing process, the retract distance of the build
platform, do not change if not necessary.
Retract Distance: In the normal layer printing process, the retract distance of the build platform,
do not change if not necessary.
Bottom Lift Speed: During the bottom printing process, the moving speed of the build platform
away from the printing surface each time, the default setting is 75+230mm/min.
Lifting Speed: In the normal layer printing process, the moving speed of the build platform away
from the printing surface each time; the default setting is 75+230mm/min.
Bottom Retract Speed: During the bottom printing process, the moving speed of the build platform
is close to the printing surface; the default setting is 230+75mm/min.
Retract Speed: In the normal layer printing, the moving speed of the build platform is close to the
printing surface; the default setting is 230+75mm/min.
Parameter Mode: The default static mode allows the printer to print according to the parameters
set in the slicing software, or you can choose the high-speed mode or smooth mode, the printer
will dynamically adjust the printing parameters according to the complexity of the model to
improve the printing quality and printing speed.

Machine Maintenance
Please do not use sharp or pointy tools to scrape the resin tank to avoid damaging the release
liner film.
Please clean up the resin tank before changing the resin to another color.
Before and after printing, clean the build plate with paper towels or alcohol to ensure that there
are no bumps or burrs on the build plate.
Before each printing, daily check the exterior of the machine and all mechanical parts for any
obvious damage, defects, or abnormalities.
Try to keep the printing environment at 25-30 degrees Celsius when printing, and ventilate the
printing room as much as possible to facilitate heat dissipation of the machine and resin odor
volatilization.
If the Z-axis keeps making friction noise, please add some lubricant to the lead screw. Please
check and apply lubricant grease at least every 2-3 months, and increase the frequency of
application as the printing frequency increases.
If you don't use the printer in the next 48 hours, please pour the remaining resin from the resin
tank back into the resin bottle and seal it well. If there is any residue, please use a filter to filter
it out.
Check the condition of the release film before each printing, and observe whether the release
film is loose, whether there are scratches or severe whitening on the surface, and if so, replace
it in time. The release film is a vulnerable part, please replace it at least once every 1-2 months,
and increase the replacement frequency as the printing frequency increases.
Please be careful when removing the printing platform to prevent damaging the LCD screen.
The service life of the screen is about 2000+ hours and will decrease with increasing printing
frequency. Do a good job of daily screen cleaning, and unplug the machine in time after printing.
If there is a screen exposure problem or service life has seriously affected the print quality, please
replace the screen in time.

Warranty Statement
1. From the date of purchase, ELEGOO printer is entitled to 1-year free warranty service, except for
consumables of the LCD screen and the release film.
2. The LCD screen enjoys a 6-month free warranty service.
3. The free warranty does NOT include problems caused by self-disassembly and improper use,
