Turn off bridging in Bambu Studio

Is there a way to stop the slicer adding bridging on an overhang?

My part is printing in PLA and has a thin horizontal slot. Printing support in place for the slot is very hard to remove from the slot. So I came up with the idea of pre-printing a PETG piece that fits in the slot and provides support. So just before the overhang is printed the job pauses, I insert the pre-printed support then resume. After printing, the PETG piece is easily removed in one piece.

But the slicer insists that the “overhang” is printed as bridging as there is no way I can tell it it is fully supported and can print a normal shell. The surface finish of the top of the slot would be better if it printed a normal shell layer.

Couldn’t you just use a support blocker there? Just in that slot?

There is no support to block. The slicer just sees an overhang and adds bridging. I’d use a modifier but there doesn’t seem to be a way to turn off bridging.

Edit. Reading comprehension kicked in. Sorry.

Just speculating a bit here in the absence of pics: Could this be a result of overextrusion due to the bridge flow being (usually) set to 1? In that case, lowering this value to the flow ratio of the calibrated filament may help.

I myself use a dual AMS so I have not had to tackle that particular problem myself.

A bridge is just like any other extrusion type except you can control flow, speed and cooling separately from any other extrusion type.

If there’s something below it, the special bridging settings may not be necessary, but they shouldn’t cause a problem.

Leave flow set to 1, change bridging speed and cooling if you want to, have at it.

Hi folks ,

I am currently looking for a way to disable bridging in Bambu Studio. While the discussions around this topic are quite engaging, I have yet to hear a direct answer to Paul’s question. Can anyone confirm whether it is possible to turn off bridging? Just need a yes or no :+1:
