Layer separation looks a lot like warping except that it happens on layers other than the first one — layers of your print are warping off of each other, instead of off the build plate. This usually happens at sharp corners of your print, and is much more common with ABS and ASA materials.
Certain materials (ABS and ASAs) are prone to layer separation. This is because they print much better if they cool down slowly. As they cool they shrink slightly, and if that happens to certain parts of your print faster than others they’ll peal away and separate.
Turn off your active cooling fans when printing ABS or ASA materials. This can help them to cool down more slowly, and stop layers from contracting too fast and separating.
To insulate your print, you can print a draft shield. This will let your print cool down more slowly, and more uniformly. Draft shields effectively simulate an enclosed printing chamber and will not perform as well as a real enclosed build area (which can help with this issue as well).
