Rendered still image output different from viewport render
Not entirely sure what the issue could be...
I'm on 2018.3 and i get a lot of missing external files when using the scanline renderer:
And the rendered object turn out black, except for the ground object:
But if i switch to the ART renderer i get no errors and the following result:
And with Arnold as renderer:
So i guess you might have an issue with the applied materials being incompatible with the renderer you're using...
I won't get the honeycomb structure since i'm missing whichever plugin you used to create it, but your scene looks fine to me.
I might not understand your problem exactly though...
If it's really just about the difference in appearance between your viewport and the render, that (at least to me) is normal.
Just look at the lighting difference on my latest project:
I never take the viewport for anything more as an indication and use the activeshade window to get an actual preview of what my scene will look like rendered.
(this scene is lighted with an environment HDR image, no local lights)
I can't make a proper comparison, i'm missing a plugin you're using:
Without it, the model just looks like this:
It might help if you set up a HDR image for the environment, it's easier to create realistic lighting that way:
(my quick preview is a bit overexposed, but that can be changed in the same dialog and depends on the HDR used)
Oh sorry again hear is the plugin.

Ok, now i have some more geometry to work with.
Lots of images coming up, i'll insert them a bit smaller so click on them for full size.
First off, how your file looks with the different renderers without changing anything:
scanline
Art
Arnold
I then changed your free lights to Arnold point lights and adjusted their intensity:
And this is with the lights turned off, using a HDR image as lightsource:
I then made a wax material and applied it to your model, this is what it looks like with the HDR and both lights turned on:
And with the HDR turned off, but the Arnold lights on at different intensities:
So, from what i could tell... Scanline and Art seemed to have a bit of a problem with the geometry... which looked like normals facing the wrong way.
But overall the lighting did work.
As i know Arnold a bit better i had no issue getting your model lighted properly, but it worked better after changing to the Arnold lights.
You may notice that in the images where i changed to Arnold lights the viewport is completely overexposed, it looks nothing like the render.
This is why i don't take the viewport for anything more as an indication.
Not sure where you want to go from here, let me know what you think.
Thank you very much for doing the hard work for me.
Though I could not find "Transmission" in Material Editor"Standard surface" I think that is why my end result is....
Yes, Transmission is part of the Arnold standard surface material.
For the scanline standard material i think you need to either edit the opacity or go into the extended parameters and edit the "advanced transparency" options.
Be sure to edit the index of refraction (IOR), according to the internet it should be around 1.44 ~ 1.449
---edit---
just saw your image of the material... looks like you are using Arnold, but you might be on a different version.
