3D Printing Forum

I have tried several times and the print splits toward the build plate. The tube is hollow, so I don't think it's a suction issue. Any idea what might be causing this, appreciate the help.

Could use more information about the print.
What filament
What Nozzle Temp
What bed Temp
Is the model being printed in a temperature controller area or could a cool breeze cause the split.

Please give us more information to work with.

I'm using Sunlu High Toughness Resin, the printer has a heater and the resin is a constant 76F, calibration indicated a 2.2 second layer exposure was best. In my garage with the door closed and lid down so no breezes.

Could you show a side view, as if you are looking directly at the printer.
I had a problem like this a while ago, I think it was a support problem, they were too thin.

Thanks for the reply, here are some more views

Let me try this again, keep getting a HTML error.

I think the part might be flexing while printing.
Try thicker supports.

in my experience cracking can sometimes be from Lack of Support
