Newbie to 3D Printing

[icmc]

Hi all
Being a new member of this forum no one has asked those questions already.
I do not have a 3d Printer as yet and want to buy one. The reason being I would like to print things for my cockpit I would love to build for an Airbus A 320.
I am looking to buy the Bambu P2s AMS Pro.
When printing what is the best way to print a part that also has LED's behind it? Do you use any filament at those points at all or will they be empty?
Also if I can get files for parts to print will they have the information already stored which filament to use and do everything automatic or will I have to do that.
As said I do not have a clue and hope anyone here can help me.
Thx
Ian
