How would you replicate this?

I'm a veterinary anatomist and I'm venturing into the world of art with the intention of replicating real anatomical parts of animals. This is an image of a real horse's large intestine that I prepared with polyurethane expanding foam to maintain its shape (the piece measures about one meter long, half a meter wide, and about 50 centimeters high).


 I want to create a synthetic piece like this (I thought maybe using flexible foam so it wouldn't be too heavy) but I don't know how to copy it. I don't know if the best way would be to directly copy this piece with silicone (rebound or body double), or perhaps scan and print it and then sculpt over the printed piece (I don't talented enough yet to just sculpt it out from zero), but I don't know what kind of mold to make afterwards, and what material to use for the final piece. The intention is a piece to be used for teaching, it has to be light. Any recommendations? I'm a beginner.

    A silicone mold with an epoxy/fiberglass mold shell would be one option.  The challenge would be determining how many pieces the mold needs to be to work around undercuts and the various forms.    Once you have the mold, you could do a self skinning urethane foam for the final lightweight piece.  (or something similar)

    For someone new to mold making, this is a very difficult subject with lots of complicated forms and undercuts.    You may want to work your way up to it by starting on some simpler pieces first.
