Variable layer thickness on SL1

I would love if there were a way to print models with multiple layer thickness. It does not have to be variable thickness as in the prusa-fdm style, but just something to speed up printing in areas where details are not important and then print to a high resolution in other areas. Typically when printing in 0.025 mm layers, I think the support structures at the bottom could be printed in 0.1mm layers and then thinner layers after that.

Some way to define layers for between certain heights eg:

Bottom to 5.8mm=0.1 mm layers

5.8 to 22mm=0.05 mm layers

22 to top=0.025 mm layers

Maybe someone knows a workaround already?

Don't know any workarounds, but I think it would be a nice feature, just like in FDM printing. Try suggesting it as a Feature Request at the issue section of PrusaSlicer.

Have a look at my models on Printables.com 😉

Thanks, I posted there.

I also found this https://github.com/prusa3d/PrusaSlicer/issues/3191#issue-523149933

Disappointingly, that post is almost a year old.

Looking at the results in the post, its a huge gain in print speed (2x - 10x for 10 - 100um).

Combined with the current anti-aliasing the variable height would keep the same high surface smoothness.

Here is a nice YouTube video showing a solution to variable layer problem in SLA: Variable Layer Slicing for 3D Printing
