Chocolate is an interesting and challenging material to work with because it requires accurate control of viscosity and temperature conditions. The melting point of chocolate is between 86° F (30° C) and 90° F (32° C). When the chocolate cools back to room temperature it will harden again. Although chocoate has a very narrow working potential for extrusion, you still can do a lot of interesting thing with it. If you can control the temperature, chocolate is a material which is particularly well suited for extrusion 3D printing.
