Polar 3d food printer

NASA Space apps challenge- printing food in space project; We didn't win the challenge but i think the idea is great and the machine is feasible in practise so here is the concept if someone wants to try building it or expand on the idea. The machine is based off of polar 3d printers so the extruder head(s) only move by the z axis and the plate beneath does the moving going under each extruder head filled with different types of ingredients ultimately building the recipe and finishing the process in the built in oven (forced air convection was my idea but it isn't necessarily the best choise) .
