Adhesive dispensing device

A method of rapid prototyping to form a three dimensional model comprising generating a three dimensional model using a stack of individual sheets of paper that are successively bonded to one another using a water based adhesive, the method comprising:

• (1) attaching a first sheet of paper to define a base of a build object to a build plate;
• (2) depositing the water based adhesive to an upwardly facing surface of the first sheet of paper;
• (3) placing a subsequent sheet of paper on the adhesive on the upwardly facing surface of the previous sheet of paper of the build object to define a layer of the build object;
• (4) cutting a two dimensional profile, comprising operating a cutter to describe a path of the two dimensional profile of said layer of the build object and in doing so cutting out a form of that particular layer of the model;
• (5) depositing the water based adhesive in controlled amounts to specific locations of an upwardly facing surface of a topmost sheet of paper on the build plate;
• (6) placing a next sheet on a topmost adhesive layer of the build object to define a next layer of the build object;
• (7) repeating steps (3) to (6) until the entire three dimensional model has been built up layer by layer.
