STL Export Curved elements facets

Morning all,
does anyone know if there’s a settings that affect the STL Export facet ?

I get highly faceted curves when i export from a geometry created in Dynamo even though it’s perfectly round :slight_smile:

Not sure if it would help, but you could try different unit options available on one of the nodes

STL for 3D printing not SAT but i will try the SAT into Rhino then back to STL :slight_smile:

I would use the meshtoolkit export node

Sorry :zipper_mouth_face:

Not sure if it is relevant, but, in an online STL viewer changing Display option from Flat Shading to Smooth Shading seems to smooth a faceted surface.
