14.3. Spilled resin
Always use the protective tray
and exercise caution when handling liquid resins. If you manage
to spill resin inside the printer (e.g. through the tilt bed),
turn off the printer immediately and
disconnect the power cord.
Locate eight screws on the body cover (four on each side of the printer), remove them and take off
the metal body cover. Inspect the damage: in case there’s just a few drops of resin, it’s very likely
that they’ve been caught by the tilt bed assembly. Wipe them clean and make sure there are no
leftover drops anywhere. Put the cover back and check whether everything works fine.
In case there’s a major spillage (e.g. on the mainboard), keep the printer turned off and
contact our tech support.
15. Print quality troubleshooting
When you print on SLA printers, you may encounter several print quality issues. The following
section will help you recognize them and solve them.
15.1. Removing an object stuck to the bottom of the tank
In case the first layer did not stick to the print platform, it remained
stuck at the bottom of the
tank.
No matter how big or how small the stuck layer is, there’s a quick safe way that will help you
remove it from the FEP film without damaging it:
Unscrew the resin tank screws and remove the tank
1.
Take an empty bottle and insert the bundled funnel/filter in it
2.
One of the tank corners has a different shape, use it to pour the resin from the tank into the
3.
bottle. Always pour used resin into a new bottle; don’t mix it with unused liquid - especially if
the print failed.
Wipe the tank with a soft paper cloth. The layer that got stuck should be now fully visible
4.
Keep the tank in a horizontal position and
use your fingertips to press from the underside of
5.
the FEP film against the stuck layer.
This will detach the solidified layer from the bottom.
Use a reasonable amount of force and don’t use your fingernails. If the layer is larger, start
from the edges and use a circular motion to detach it evenly. You will usually hear the sound of
the layer detaching from the FEP film - this indicates that it’s working.
Once the stuck object is removed, clean the printer and the tank and try printing a sample object.
If the print fails again,
re-run the calibration process.
The most likely cause of this issue is an
incorrect Z-offset of the print platform.
15.2. First layer doesn’t stick (Non-Adherence)
If you notice during the printing process that no object appeared on the print platform, it usually
means that
the first layer didn’t adhere properly,
or the object detached mid-print. To rule out
slicing-related issues, try printing a sample (pre-sliced) object first.
There are a number of reasons why the first layer does not stick to the print platform:
a) The print platform is not secured properly
The print platform is not properly secured. Make sure that you didn’t forget to
tighten the black
