US 2021/0268728 A1 · Jettable Temporary Solubolized Peek Binders to Create Removable Support Materials

Abstract

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.

Dependent claims

A method for manufacturing a three-dimensional article, the method comprising:

(a) depositing a powder on a build plate to form a powder bed;
(b) printing, at selected locations on the powder bed, a solution of:
a first binding agent;
and/or a second binding agent;
(c) exposing the first binding agent to a stimulus to form a polymer layer;
repeating steps (a)-(c) to manufacture the remainder of the three-dimensional article;
and
removing the second binding agent;
wherein the first and second binding agents are each printed at least once;
wherein the first and second binding agents are printed at different selected locations on the power bed;
and
wherein the second binding agent comprises a solubilized polyetheretherketone.
