摘要： 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 three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.

摘要： The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of powder is deposited on a build plate to form a powder bed. Then, a sintering agent is printed on the powder bed in a predetermined pattern. The printed sintering agent is exposed to stimulus which results in the selective sintering of the power printed with the sintering agent. Sequential layers are printed to provide the three-dimensional article. The sintering agent may include a croconaine dye. The sintering agent may further include a surfactant. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.

摘要： The present invention provides high performance polymer (HPP) compositions, methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using molding or 3D printing. The HPP compositions comprise a first HPP dissolved in a solvent and a second HPP present as a solid.

摘要： 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.

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.
