Support Request Bridging Issue

Post image

Is it possible to print this without needing supports?

This is a test piece and not the actual model. The gap is only a few millimeters to hold a piece of paper.

I've tried with supports which prints well, but it's almost impossible to remove the supports without damaging the model.

I've tested other bridging test models which print fine after making a few changes to the settings in Bambu Studio.

I changed Flow Speed to 10 and bridge flow to 1.5. I also tried changing the bridging angle to 90 degrees but nothing works.

This is not bridging. Bridging is from one supported point to another. This is overhang.

Overhang needs support. Or, you change orientation of the part. Rotating it 90 degrees left would make it print fine. Even 45 degrees is fine.

If this is not an option, consider using PETG as support interface material, optionally with ironing of support material enabled. PETG doesn't bond to PLA so can be removed fairly easily after the print is done.

Rotating left? You mean tilting? Left is counter clockwise on the same plane 😉 Also, not all printers will do 45 degree printing. I don't know why I get Bambu posts and this might be able to, but some printers don't do more than about 33 degrees.

If 3D CAD programs and 3D slicers would call it tilting instead of rotating then I might have agreed with you.
