It's of course it's perfectly doable to slice your core model with any other slicer, but because of classic slicing process limitations, the core with sufficient stiffness will end-up significantly heavier then strictly needed - fine for pattern/dimensional prototype, less then stellar for functional prototype/production part.

Looks like a lot of information I need to assimilate. thanks Which video did you see EC using a 3D printed plug? Their video is not a 3d printed core, but skinning a solid object would be the same despite what the material is. This video they are skinning a gun stock. You should be able to follow this procedure the same. It takes a good bit of sanding Easy Composites skinning video

L Group: Forum Members Posts: 19, Visits: 110	+x Joe LaCour - 8/4/2020 9:18:10 PM 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. Sorry just re-read and you wanted to skin your parts with composites. I have done this on a small wing and it worked fine. Easy Composites has a good video on YT for the skinning process that you should watch.

My 3D printer certainly is not dialed in but found that it needed lots of sanding and prep to make a mould from the print. Sanded, primed, body filler, more primer then a mould could be made. Sanded and mounted onto wood. Total length is around 31 inches (done in 6 prints due to my printers limitations) After much bodywork all waxed ready to make the mould:
