Herein you will find details on my quest for the “perfect” FDM printed stone surface.
This is NOT a general guide on getting high quality FDM prints for terrain - it is specifically focused on models (typically terrain tiles) with large areas of relatively flat (parallel to print bed) but irregular top surfaces.
The goal is to end up with a primed print ready to paint with effectively zero FDM artifacts - especially layer lines. In my case there are two motivations for this goal :
I don't think it's feasible to directly achieve the desired level of quality with the current generation of basic (I'm working with Ender 3 Pros) FDM printers, although that may change (perhaps ironing mixed with non-planar slicing…). This means that for now there will need to be additional post-print processing to smooth things out prior to painting.
Some of the specific goals include :
