I found that using three
types of chocolate (melted
chocolate, cocoa powder, and whole
chocolate chips) provides multiple
layers of chocolate flavor, which a bit
of espresso and vanilla only seek to enhance.
1) Extrusion: liquid material is ejected from a syringe, much like frosting, in
layers (warmed plastics, clay, silicone, warmed soft metals and edibles such as
chocolate); most printers on the retail market are
of this
type.
