But 3d printing is not food safe, so using this method for chocolate molds seems unwise.

  It can be food safe. You can even print invisalign-style braces. https://formlabs.com/store/us/form-2/materials/dental-lt-clear-resin/ https://formlabs.com/store/us/form-2/materials/dental-lt-cle...

  The molds are not 3D printed. Rather, the molds for the mold are. The actual molds used in production are silicon, obtained after pouring silicon into the 3D mold-of-the-mold.

    FWIW mold for a mold is usually called a pattern

      Pattern is the object you want to have produced. Metamold is a mold which gives you mold which then can produce your pattern.

  The 3-D printed molds are used to make silicone molds. It doesn’t really matter how bad the 3-D printed molds are as long as they don’t ‘infect’ the silicone molds while you’re making them. The video shows it being used to make fancy ice cubes.

  PETG polymers, printed with sufficient fidelity are food safe, and available on FDM type printers.
