no additional materials required. I chose to print the base in Bamboo-filled PLA from ColorFabb, and stain it. I printede the water and water supports in Blue Tglase, then covered it with a thin layer of normal 2-part epoxy. The Pig was printed in White ABS, before being sanded, cold vapor treated, painted and enameled. I did have to sand a bit off the pig's feet to retain clearance once paint was to be added.
