# What could cause delamination in the raft?

(Asked by: username_0 on 2023-04-19)

I got a brand new Anycubic Photon Mono 4k about a week ago. Printer is new, FEP is clean, it was a fresh load of Anycubic Standard+ resin.

I got a couple of good prints, including perfect Cones of Calibration, miniatures etc, just things you print in your first week (I had Photon S before). This time I tried to print big, but flat and hollowed out model. Think vault door from Fallout. It was too big to print flat, so I tried standard 45°, heavy support, 90% automatic support density and then some when I felt like. About 5% in the print I noticed something weird, cancelled print, and that's how it looked like.

It delaminated in the middle of the raft. I *guess* it was just after bottom layers.

So, what could be the cause, and how can I prevent it from happening again?

I had delamination previously, but never in the raft.

My exposure was tested, seems perfect, and other delamination advice seems not applicable for delamination inside the raft.

I'm not sure what exactly *was* the problem, but setting **Transition Layers Count** to **8** apparently solved it. I have no more fails since I did that, and one failure when I tried printing without them, for experimental purposes.

I would love to see an explanation of the mechanisms of this error, for now I share what worked for me.
