I have a Bambu Lab A1 and I’m pretty new to 3D printing and using slicing software. I have been editing a model of a video game map (gm_construct from Garry’s Mod) in blender for printing.
I have encountered a problem in which a section of the model that (to me) looks like it should clearly be a bridge is instead being sliced as an overhang. This lead to that section of the model being pretty mangled upon printing.
Here is an image of the model in blender pre-slicing:
I’ve tried changing the layer height, wall generator (classic to Arachne), line width inner/outer, and enabling support all to no avail. I’ve also tried slicing it in orca slicer with the “Detect overhang walls” setting turned off and it just marks it all as outer walls with nothing underneath.
Is there a way I can encourage the slicer to recognize the beams as bridging sections? I’m really not sure which settings in Bambu Studio would help. Maybe I need to tweak the model slightly in some way? Any tips would be appreciated!
There are a whole bunch of related issues at play here. There is buggy behaviour that has been present in BS and Orca for a very long time. I think everyone runs into this.
Upon further reading of the github thread posted above by movingimage, I fixed the issue with Orca slicer by setting “Bridge counterbore holes” under Quality > Bridging to “Partially bridged”.
