Resin printers don’t have a “filament size,” it’s the resolution of the screen that cures an ultra-thin sheet of resin, separates, and repeats until the shape is formed. If the model was spherical, the object would be nearly a perfect sphere by visual inspection. They fed it a faceted, low-poly sphere you could pull off with a fdm printer (filament deposition). As far as detail, FDM = le Potato Cutter, Resin = DaVinci Robotic Surgical System.
