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.
Claims15
A method for manufacturing a three-dimensional article, the method comprising:
- a. depositing a powder of a first high performance polymer (HPP) on a build plate to form a powder bed;
- b. depositing a composition at selected locations on the powder bed wherein the composition comprises:
- a homogeneous mixture of a second HPP dissolved in a solvent;
- wherein the composition further comprises particles of a third HPP that are dispersed in the homogeneous mixture of the second HPP and the solvent;
- and
- wherein the particles of the third HPP are insoluble in the homogeneous mixture;
- c. exposing the deposited 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.
