A method for producing an anatomical model, comprising:

• providing a mold assembly, comprising:
• a first mold portion having an outer surface and an inner surface;
• and
• a second mold portion having an outer surface and an inner surface;
• disposing a lining material on either a portion of the inner surface of the first mold portion or a portion of the inner surface of the second mold portion, or both;
• forming a first cavity between the inner surface of the first mold portion and the inner surface of the second mold portion;
• positioning a portion of an insert in the first cavity, wherein the insert has a protrusion having a portion disposed in a channel extending through either the first mold portion or the second mold portion, or both;
• introducing a first material into the first cavity;
• removing a portion of the insert to expose a second cavity inside the mold assembly;
• and
• introducing a second material into the second cavity.
