Delamination / Separated layers
If you encounter delamination, separated layers or missing layers, the cause is usually in a broken SL1 / 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.
Solution: Try printing a sample object and see if the issue persists. If it does, clean the resin tank properly and try again. Continuous issues with separated / missing layers can be caused by a faulty UV LED panel – check whether it works correctly. Otherwise, the cause is most likely a broken object file. Either try re-slicing the model or download a new one.
