3D Printing Software missing surfaces

Greetings to all the members!!
Recently i purchased an anycubic Mono 4K 3D printer. It's not the Best Printer but it's worth the price.
I design an aircraft and cut it in two halfs because of internal parts assembly. I use Solidworks and the 3d Print software (Slicer) is Photon Workshop V2.1......
The problem is, that in solidworks the model is seems good, but when importing it in slicer, some of the surfaces are missing....and the same thing is happening any time i import it as STL graphics in solidworks..
Any advices or guidance to troubleshoot?

Check the thikness of your designed surfaces - your production technology (FDM) uses a nozzle with a specifig diameter - your slicer is not able to produce infinite thin walls. I would say that is the reason why suddenly surfaces disappear.

Check that your model has a watertight mesh, i.e. that it is a solid model comprised of solid bodies without any surface-bodies. Since surfaces are infinitily thin (per definition) they may not print because they don't have any enclosed volume.
