Saving a Spleen with 3D Printing: Pre-Surgical Planning with Medical Models

Not many of these articles mention that most 3D printers leave the model in a less than perfect state. It is covered in little flaws due to the print process and also covered in scaffolding.

There is a really interesting instructable on how to polish up the resulting epoxy model (this is a model of a horse leg muscle attached to the leg bone): http://www.instructables.com/id/How-to-Polish-Resin/

Many hours needed to sand the model, then apply polish compound and then finally buff with wax.
