Methods for Solid Freeform Fabrication

摘要

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.

主权项

1. A method for manufacturing a three-dimensional article, the method comprising:
a. printing a solution of prepolymer on a build plate; b. exposing the printed solution to a stimulus to form a polymer layer of the three-dimensional article; and c. repeating the steps (a)-(b) to form remainder of the three-dimensional article.
