Ultimaker Cura slice model

[julyjoy 0]

Hi everyone, Ultimaker is brand new to me, I scanned a basic model with a scanner, the model was very small, maybe around 30mm, I tried printing it with ultimaker3, but it didn't go very well, UltimakerCura can't seem to slice the small ones properly Model. I would like to know how to set up and adjust the settings in Ultimaker Cura to get better printing of small objects.
Is it possible that there is a problem with the model itself that prevents Cura from successfully slicing small objects? Do I need to check the model's geometry, dimensions, or other issues?
Or is it a problem with parameter settings, such as layer height, wall thickness, filling density, etc.?

3D scanner: MIRACO 3D scanner
3D printer:ultimaker3

Slicing software: Cura
I'm hoping to fix this, any experience or advice would be greatly appreciated

If you could provide the Cura project file (.3mf, get it set up in Cura then go to File > Save Project) we can dig into it for you. 3D scanners aren't always the greatest at exporting completely valid models but I find Revo Scan isn't too bad a lot of the time.
