There seems to be an increased desire for controlling the wall thickness around holes independently from the model wall thickness. This would be an excellent feature to include in Bambu Studios.
The specific need for this control is mainly related to screw holes. Typically, the walls around a screw hole are not fully bonded to the screw hole ‘ring’ of filament completely. This can result in screw holes that easily strip out on models. Adding additional walls to screw holes may increase bonding to surrounding walls.
Great idea! Not only for srews but also for e.g. melt in nuts.
There is at least a workaround: we can add a modifier at the position of a hole ( a little bigger than the hole) and specify e.g. 100% infill. But htis has to be done for every hole. And positioning modifiers is not simple.
I wonder, if in fusion or something, (I have no experience) we could do this a bit easier
3 “parts”
Main model
Hole sections
Outer Ring - with the 100% infill much larger circumferance
Inner ring - with the negative part'hole’ centered within #2.
a) If modelling these as separate parts, they could be assigned different infills and setttings in slicer, and yet assembelled\printed one … rather than try and do separate modifiers in the slicer.
b) #2 and #3 would be a template to copy\rinse\repeat in fusion for as many of these holes you need?
We STILL have the same issue - of the ‘hole’ walls bonding, but its wider load spreading? will that even work? Just a theory- I am only just learnig fusion, until bambu gives is wall control like this direct in slicer.
OR @newsletter is this exactly what you mean? In fusion or whatever?
You can even create privitive objects directly in bambu studio and use them as modifier. I tried it and observed the sliced output, put I did not priint it. (I did just a test, if this would work and was partly satisfied.)
Be careful! If you save or export as stl the modifiers are lost.
I dont want to start a religious battle about 3d design tools, but just say, I dont like fusion. Since I am not a professional 3d designer and are doing 3d printing just as hobby the paid version is too expensive for the rare occasions I will likely use it. And the free version is to restrictive. It does not even allow me to create parametric designs.
I found this video https://youtu.be/OoKlGKnWuFc Solid Infill Modifiers for Bambu Slicer
Maybe I will try to do something like that.
I thought about your idea. A general setting in the slicer for holes would be great, but on the other side you might have holes of different sizes. And maybe the slicer finds holes which you dont think to be holes. So I had a little improvement of your idea:
If the slicer would (optionally) add the holes automatically to the parts, then we could specify settings for each hole individually and easily.
There is a parametric workbench which is disabled. Maybe there are workarounds. Or there exists different free versions. But thanks for your hint. Maybe I will look sometime. For now I am happy with freecad and blender.
When did you last try fusion (assuming you mean fusion 360 here). The free version has no restrictions (or at least none that have hampered me.) and the designs are parametric. The main restrictions is that you cannot use it for commercial purposes and as a hobbyist you cannot generate more than $1000 annually.
I installed it about 3 month ago. Download was uncomfortable. Maybe it is easier from US, but from Europe you will pushed from one server to the next. Than I had to register. (To get now spam.) Maybe versions / restrictions differ between US and Europe, I dont know.
Every time I wanted to use the program I had first to log in online. And with the free version you can store your designs only online.
they can steel your designs without your notice
they might restrict the usage further, or even stop the free version completely. Then you have to pay or you will loose all your designs.
and also loose the effort you made to learn how to work with this programm
Everybody is free to decide what he / she likes. I decided to use something else.
