Hi Asasnegra,
This can be a result of cupping. “This occurs when a hollow or convex portion of a part acts as a suction cup and traps air while printing. As the build platform pulls away from the tank during the peel process, the empty space within the cup increases. This reduces the air pressure within the cup to create a pressure differential that pushes inward on the surrounding cup walls. If the walls are too thin and unable to withstand the pressure, then they buckle inward to equalize the pressure.” You can try re-orienting the part to print on its side, or visit the cupping blowout page for more troubleshooting steps. If the issue persists, please submit a support ticket here.
