Dynamic layer thickness

Hi,
I’m building some fancy engineering stuff and I wonder if it’s possible to alter the layer thickness layer-by-layer? I found something in OrcaSlicer that’s coming close to what I want but not exactly.
I’ll try to give an example:
suppose a model has a height of 5.7mm (yes - sometimes I want it to be exact at a tolerance of 0.1mm - which is achieveable with P1S). So printing at 0.2mm thickness brings me close, but not exact. By changing the thickness during the slicing process, it would be possible to get a much tighter tolerance.
Same question obviously for the wall thickness. Best way to imagine what I want:
think of a sphere with a wall thickness of 1mm (roughly 5 walls at 0.2mm). At the equator, this is exact, closer to the poles however, this is another story.

Any ideas? I could use Orcaslicer, but that doesn’t solve the first issue though.
Thanks

Bambu Studio can do variable layer thickness too but it’s primitive. It looks at detail inside and outside a model too.

When you enable it, you’ll get a layer thickness gauge on the right of your screen that you can modify with the mouse to make layers thicker or thinner but it’s kind of clunky.

What many want to use it for is helping control stepping in the layers on broadly-curved upper surfaces. It seems to want to do the whole model though that you apply it to.

What is really needed is standard as-specified layer height from the first layer up to some height where you want variable layers to take over to help conceal the plateaus. I haven’t found how to do that. If anyone knows?

some sort of AI to achieve the best proximation to expected wall thickness and height tolerance. Why else would I want to invest in a precise printer, precise 3D scanner with tolerances up to 0.01?

This would be very useful. I would like this to save time, I have certain areas that are very precise (minimum thickness laywes) and other areas that can be wide open (maximum thickness). On a 30 hour print, this could save me very much time.

You can use ‘precise Z height’ in BS for the height. It is on the Quality tab under Precision.

Thanks for that tip. I found it, clicked the “precise Z height”. I do not see how I control the height from here though. it says it changes the height to create a precise height object. I want for example, the first 100 layers at thickness 0.06mm and the next 1000 layers 0.12mm

To be more clear. I want to control which layers are printed at thickness x and which layers are printed at thickness y.

If the only parameter you care about is the exact total height, just use “Precise Z Height”

It will automatically select and adjust a couple layers to solve for the correct height, and you can move your attention elsewhere.

Sounds like you want to control more than that though, and you want to use variable layer height. Variable Layer Height | Bambu Lab Wiki
