Jettable temporary binders to create removable support materials

A method for manufacturing a three-dimensional article, the method comprising:

• a. depositing a powder on a build layer to form a powder bed on top of the build layer;
• b. printing, on the powder bed,
• a first solution of a first binding agent at a first location on the powder bed which penetrates the powder bed to the build layer;
• and/or
• a second solution of a second binding agent at a second location on the powder bed;
• c. exposing any first binding agent and second binding agent printed in step (b) to one or more stimuli to bind together the powder on which a binding agent was printed so as to form a new build layer that is bound to the original build layer;
• d. repeating steps (a)-(c) to manufacture the remainder of an intermediate three-dimensional article;
• wherein the first binding agent and the second binding agent are each printed in the same layer at least once and
• wherein the first location and the second location are not the same;
• e. removing the intermediate three-dimensional article from a build plate and removing unbound powder from the intermediate three-dimensional article;
• and
• f. removing second binding agent from the intermediate three-dimensional article so as produce the manufactured three-dimensional article, wherein the manufactured three-dimensional article comprises the first binding agent;
• wherein the second binding agent is a self-immolative polymer.
