knob at the top of the tower.
A freely moving print platform cannot reach an optimal position and
the first layer won’t stick.
Solution:
Tighten the black knob at the top of the platform.
b) The bottom of the tank is cloudy/dirty
Before you pour the resin into the tank, make sure that the bottom of the tank (the FEP film) is
completely clear.
A cloudy, dirty or damaged FEP film will have a negative impact on the
printing quality
and it may even block UV light enough to stop the resin from solidifying properly.
Solution:
Clean the FEP film using warm water and a bit of dishwashing product, and wipe it with
soft paper towels. Low quality / rough paper towels could scratch the surface.
c) Incorrect slicing settings
There’s a couple of things that may go wrong during slicing - incorrect exposure times, an
incorrect object orientation or a lack of supports.
Make sure that you are using the
recommended exposure times
for the resin of your choice. We
have tested over a hundred of various resins and we’re constantly testing new ones, so we can add
tweaked resin profiles into PrusaSlicer.
Solution:
Reslice your model using default settings and try printing the object again, or try
printing one of the sample objects to rule out the possibility that slicing settings are the cause.
The exposure times for initial layers should be much longer - e.g. 25 seconds to ensure a strong
connection to the print platform.
d) Poor object orientation / insufficient supports
Incorrect object orientation
can be another source of issues with adhesion. After a layer is
solidified, the printer has to detach it from the bottom of the tank - if there’s a single support
holding a large part of the object, it won’t withstand the peel force, causing it to detach.
Solution:
Please refer to the chapter Slicing - Best practices to learn how to position an object
correctly.
e) Resin has been mixed with IPA
The resin has been mixed with IPA (e.g. while cleaning the print platform) and its properties have
changed, causing it to not solidify.
Solution:
Clean the resin tank properly, use a new batch of resin and try again.
f) The printer is not calibrated correctly
It’s possible that something changed since the last calibration of the printer - you have replaced
some parts or moved the printer to a new location.
Solution:
A re-calibration is required. Please refer to the
4.5 Calibration chapter
for step-by-step
instructions.
g) A faulty print display or UV LED panel
If the first layer didn’t adhere to the print platform and it’s not attached to the bottom of the tank
either, it usually means that
the first layer wasn’t created at all.
A possible cause is a faulty print
display or a faulty or disconnected UV LED panel.
Solution:
Please refer to the online troubleshooting section at
to learn
more about diagnosing the function of these two parts.
15.3. Printed object has missing parts
In some cases,
a print can finish even if some parts of the object weren’t fully printed,
but a
missing part of an object will more often cause the whole print job to fail. Try printing a sample
object to see whether it is also affected by this issue.
