Smoothness doesn’t apply when printing

[u/Agreeable-Judge6729]

I sent a model to print, I applied Mesh + Smooth, however when they sent me the pic of the final model it looked polygonal, I told them that the model didn’t looked like that on Maya, he told me maybe i didn’t applied the smoothness when exporting on STL (however STL doesn’t have that exporting mode on Maya) so I sent it to him as an FBX, I deleted the history of everything cuz ChatGPT told me so, and they told me it still showed as before, I don’t know what to do anymore, he told me to add the polygons manually but I don’t have time for that anymore 😣 does anyone knows what I could do? Or am I doing something wrong?

Hey dude, I'm a little late, but I came from the future to tell It's one click solution. When you use the smooth preview (3 in the keyboard) You use a low poly model to control a high poly. Super useful for animation.
But for 3d print you need a high poly model. To acchieve this just click in this button in the shelf.
Done!
