I have an idea to make a component out of carbon fiber and in the past i would have carved up some foam for a core and overlaid epoxy and glass or carbon fiber.

Now that I have a 3D printer, I am considering printing the core and overlay with cloth and epoxy.

When searching the forum, I found only references to using 3D printing for a mold.  Maybe I did not search correctly.  Has there been anyone with experience doing this?  The core would be in several pieces and bonded together.  Preferably PLA and West System epoxy.
