METHODS FOR SOLID FREEFORM FABRICATION

摘要

The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles (35) of polymer materials using 3D printing. A syringe or an inkjet print head (30, 31) prints a solution of prepolymer onto a build plate (37). 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 (35). The three-dimensional article (35) can be cured to produce the 3D article made from the final polymer.
