Abstract
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.
Claims19
A composition comprising a first high performance polymer (HPP) dissolved in a solvent and a second HPP as a solid.
A method for manufacturing a three-dimensional article, the method comprising:
- a. depositing a powder of HPP on a build plate to form a powder bed;
- b. printing a HPP composition at selected locations on the powder bed wherein the HPP composition comprises a first HPP dissolved in a solvent and a second HPP as a solid;
- c. exposing the printed composition to a stimulus to form a polymer layer of the three-dimensional article;
- and
- d. repeating steps (a)-(c) to manufacture remainder of the three-dimensional article.
A method for manufacturing a three-dimensional article, the method comprising:
- a. depositing a HPP composition comprising a first HPP dissolved in a solvent and a second HPP as a solid into a mold to form the three-dimensional article;
- and
- b. removing the three-dimensional article from the mold.
