I've got a problem with my printer (Bottom-Up). Sometimes this happens:

Seems like some layers aren't sticking to eachother or something. Anyone else had this problem? What could be the solution? Supports bacause of shrinkage? Longer/Shorter exposure?
Here are more details:

1mm wall thickness
FlexVat with 0.1mm PTFE bottom
X/Y: 100 microns
Slice Thickness 0.2mm
Exposure Time 10000
Bottom Exposure 20000
Z Lift Distance 5
Z Lift Speed 200
Z Retract Speed 200

Any help would be appreciated. Thanks, Matthias
