It is worth asking: Why bother converting SDFA to STL at all? Some next-generation slicers (like those using ) can print directly from distance fields. Hyperganic and nTopology are pioneering workflows where volumetric data is the manufacturing file.
So translate when translation is generous. Preserve when preservation is generous. And when you inevitably flip a loose sequence into a precise plan, keep a scrap of the original—an index card, an audio file, a photograph of the messy notebook page—so that the s d f a that once was will continue to remind the s t l what it owes to chance. sdfa to stl
