Since you have a distance, you could fairly easily implement dual contouring, I think?

Or Surface Nets. Nice compromise of speed and quality. Marching cubes needs a lot of resolution and it's imperfections are especially ugly my eyes.

Maybe mesh resolution isn't a problem for 3D printing. But if 3D printing is the main goal why bother with a mesh? Just go straight to voxels that can be fed directly to the printer.

The printer does not use voxels, it uses G-codes, which are tool paths for the print head.

True for FDM, but for SLA you have the potential rendering a direct slice of the SDF.

OK. But a voxel representation has to be a closer match than a mesh. I guess overhang, solidity etc still need to be calculated and dealt with. Which is non-trivial.

Is it that "mesh to G-code" libraries are more mature than "voxel to G-code"?
