The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of prepolymer is deposited on a build plate to form a powder bed. Then, solutions of first and/or second binding agents are printed on the powder bed in a predetermined pattern. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The removable binding agent is then removed. The removable binding agent may be solubilized polyetheretherketone. Examples of solubilized polyetheretherketone include, but are not limited to, sulfonated polyetheretherketone and/or nitrated polyetheretherketone. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.

Jettable temporary binders to create removable support materials

Methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing are provided. A layer of high performance polymer can be deposited on a build plate to form a powder bed. Then, a solution of a photothermal dye can be printed on the powder bed in a predetermined pattern. Alternatively, the photothermal dye can be added to the entire powder bed. Electromagnetic radiation can be applied, either to the entire bed or in a predetermined pattern, to form the final polymer. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.
