Publication number: 20210268732Abstract: 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.Type: ApplicationFiled: February 28, 2020Publication date: September 2, 2021Applicant: Ricoh Co., Ltd.Inventors: Chang-Uk Lee, Andrew J. Boydston, Mark A. Ganter, Duane W. Storti

Publication number: 20210268728Abstract: 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.Type: ApplicationFiled: February 28, 2020Publication date: September 2, 2021Applicant: Ricoh Co., Ltd.Inventors: Akira Saito, Koji Takimoto, Andrew J. Boydston, Chang-Uk Lee, Mark A. Ganter, Duane W. Storti

Patent number: 11014293Abstract: 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.Type: GrantFiled: March 8, 2018Date of Patent: May 25, 2021Assignees: Ricoh Co., Ltd., University of WashingtonInventors: Chang-Uk Lee, Andrew J.

Patent number: 10688770Abstract: The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles of polymer materials using 3D printing. A syringe or an inkjet print head prints a solution of prepolymer onto a build plate. The printed prepolymer is exposed to a stimulus whereby the prepolymer is converted to the polymer. After a predetermined time, sequential layers are printed to provide the three-dimensional article. The three-dimensional article can be cured to produce the 3D article made from the final polymer.Type: GrantFiled: March 3, 2015Date of Patent: June 23, 2020Assignees: RICOH CO., LTD., UNIVERSITY OF WASHINGTONInventors: Andrew J.

Patent number: 10675808Abstract: 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. The deposited powder bed is heated to about 50° C. to about 170° C. Then, a solution of activating agent is printed on the powder bed in a predetermined pattern, and a stimulus is applied converting the prepolymer to 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.Type: GrantFiled: September 12, 2017Date of Patent: June 9, 2020Assignees: Ricoh Company, Ltd., University of WashingtonInventors: Andrew J.
