Kayen: real-time ingame character to 3d printed statue

Hello everybody.

I've been lurking and occasionally posting on these forums for a while. I made several prints, mostly jewelry as that's pretty easy come up with and doenst need any texturing or rigging.

But now I have made a character for my university as part of an assignment and I would like to pose and print him. I could do the easy thing and just print him in FCS as is, but that would be really boring. so I'm going to be posing him in a nice pose that fits him.

As this is going to be my first venture into FCS printing, I was wondering about a few things. As you can see in the screenshot, this character has some shaders on him. I have some ideas on how to fake those and get more detail in the print, using displacement maps.
I was just hoping to get some advice about some of the pittfalls I could run into with printing a model like this.
If anyone has any advice, please let me know
