On the issue of food safe printing, I’ve read that no printed model is truly food grade due to small cracks and pours from bubbles within the final printed item being hotbeds for bacterial. Seeing stuff like this concerns me: http://makerbot.tv/nfh/makerbot-tv-season1-episode9-2/
Yet, I’m looking food grade PLA sources to make molds to be cast in more kitchen-ok material. Anyone got good sources or experience?
I’m also looking to purchase a Prusa all steel extruder to make it even more food safe. They are out of stock on Ultimachine :-/
