COLOR AND/OR OPACITY CHANGING LIQUID RADIATION CURABLE RESINS FOR ADDITIVE FABRICATION

摘要

Color and/or opacity changing liquid radiation curable resins are herein described, along with methods for using the same in additive fabrication processes. Described and claimed are methods for improving additive fabrication build processes by controlling, at least temporarily, the depth of penetration of a liquid radiation curable resin. The liquid radiation curable resins herein described are capable of curing into three-dimensional articles having a certain amount of color and/or opacity. The resulting three-dimensional articles possess an ability to further change in color and/or opacity, and possess excellent mechanical properties. Also herein described are the three-dimensional articles formed according to the methods of the invention.
