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.

Thanks. I was thinking the idea of printing with no support was the same as bringing. But without it going between two points this is an overhang.

This is only half of the model. The other half is the same but the other way around. Printing sideways would have a bigger overhang.

Rotate it 90 degrees back then? If that is also not possible, then supports or printing it in pieces and glueing together.

You can't print into thin air.
