Solution:
Make sure the printer is properly calibrated, tighten the black knob at the top of the
tower and tighten both resin tank screws evenly and with the same amount of force.
15.8. Print doesn’t appear / resin does not solidify
If the print
does not appear on the print platform, nor at the bottom of the resin tank,
there are
a couple of possible causes: insufficient exposure times, faulty UV panel, faulty LCD screen, or
there’s too much isopropyl alcohol in the resin.
Solution:
First try a new batch of resin. If you kept re-using one batch several times, it’s possible
the resin lost its original properties and won’t solidify anymore. Check the UV panel and LCD
screen, whether they work as intended - run the printer’s self-test and calibration to make sure the
hardware is not faulty.
15.9. Printed object has very visible layers
Even though SLA printers can achieve much better resolution than standard FFF/FDM 3D
printers, layers on objects can be still visible if you look very closely. If you feel like the layers on
your prints are too visible, there’s a couple of things you can try.
Solution:
Print a sample object with a good/tested resin (like the sample bottle of Prusa Orange)
and see if the issue is still present. If it’s not, then the cause is usually related to slicing settings.
Try rotating the object to eliminate gradually rising / declining surfaces. Extreme exposure times
can also produce visible layers. Mixed / low quality resins can also affect the print quality - use a
fresh, high-quality resin and shake the bottle for at least 20 seconds before you pour the resin in
the tank.
15.10. Delamination / Separated layers
If you encounter delamination, separated layers or missing layers, the cause is usually in a broken
SL1S / STL file - it’s a different case than a lack of supports. Another cause can be a faulty UV
LED panel or dirt in the resin tank.
