I’ve been unsuccessfully attempting to bring this mesh to a higher quality so I will be able to print it at a more realistic looking surface as opposed to the very triangulated look it has now. Any help is appreciated!

These need to be converted to smooth NURBS surfaces. Perhaps these techniques might help: https://youtu.be/EDd2wcTKWgE?si=ZonCv-WU5Auv-lqi

This one might also work as it is a helmet: https://www.youtube.com/watch?app=desktop&v=4CzBMcP4rcA
