Not that I am aware of. If you would like to post your FreeCAD file (.fcstd) and describe what you did to mesh the part, like just export to .stl, or meshed it first in the Mesh Design Workbench using..., etc., maybe we can tell if it's the model, which we can address here, or something else. I use FreeCAD exclusively for making the models I print and have had no problems with the .stl files. IMO, .stl export is something FreeCAD does rather well.
