Problem: Print with 3 extruders Ultimaker 3 Extended

[JorgeRL 0]

I am doing a work at the university. I have an Ultimaker 3 Extended printer (it has 2 extruders: one with PLA and the other with TPU) and I need to ''trick'' the printer into ''printing with 3 extruders''.

I need to print zone 1 with the extruder with TPU and zones 2 and 3 with the extruder with PLA (but with two different printing directions). I added a '' custom '' printer and introduced the features of the Ultimaker 3 Extended printer, but with 3 extruders as I show in the image. If I start printing, will the extruder with PLA print zones 2 and 3 or it isn’t possible?

You don't need to create 3 nozzles.  You can do this with either "per object settings" or "mesh modifiers".  You can google about both features.   You need separate STL files for each area you want to have different infill and then you can either just click on each one and do "per object settings" and set the infill direction of you can have the meshes overlap where the largest mesh is the actual part and the smaller STL files (called meshes) modify the infill pattern (this is what I did below but it sounds like you can do per object settings since it sounds like you already have multiple STL files).
