I've used one of the home 3D printers and also created my own model using Google Sketchup and Blender. They will work with several common file types. The only difficult part is figuring out the size of the resulting print before it's printed.
The EQ models aren't really complicated, but one problem with 3D printing is that anything held out from the main body needs supports and occasionally won't print properly. Crazy poses are pretty much out of the question.
The texture is also not smooth on the home printers. The printer will print in layers and you can feel and see every single layer. The detail would end up being in the sanding and painting you do afterward. Not all of the printers will do colors for you.
I think it would be pretty cool to try, regardless. One thing I learned in art school is to never let what others
think might happen get in the way of trying new things. The proof is in the pudding and all that jazz.
You can also find a lot of models on Thingiverse for home 3D printing.
