I do need to export a small part to a 3D printer and I can’t get the desire result. I do tried to export in stl, gltf, dae and obj formats and unfortunately I always get a distorted mesh that don’t resemble the shape of the part that I do want to print. Even the file explorer preview in Windows11 it is showing me the wrong meshed object.
If somebody with more experience than me in 3D printing can find a solution it will be highly appreciated. Thank you.
I believe it’s just a matter of denser mesh settings, those default settings in the export options aren’t always the most ‘intelligent.’ Going in to the detailed controls and adding a number for “minimum initial grid quads” like 25 seems to make it fill in a lot better.
Your part looks OK, but I would run _DivideAlongCreases _SplitAtTangents=_Yes on it. That will subdivide the end vertical half round surfaces from the flat ones. Generally it will mesh much better after that, but I would also use custom mesh settings something like this:
My suggestion is to always use the _Mesh command to first mesh the objects to export inside Rhino, then check the meshes with Flat Shade checked in a shaded display mode. When they look good, then export the mesh objects, not the polysurfaces. You will get what you see.
Thank you for reply. The issue was that I used the default settings. I figure-out that decreasing the “Maximum aspect ratio” from 6 to 0.1 will do the trick.
