|Applicants:||DOW SILICONES CORPORATION
|Inventors:||BACKER, Michael W.
WOLF, Hans Peter
|Title:||3D PRINTING METHOD UTILIZING HEAT-CURABLE SILICONE COMPOSITION|
A method of forming a three-dimensional (3D) article comprises the steps of I) printing a first heat-curable silicone composition with a 3D printer to form a layer, II) heating the layer to form an at least partially cured layer, III) printing a second heat-curable silicone composition on the at least partially cured layer with the 3D printer to form a subsequent layer, and IV) heating the subsequent layer to form an at least partially cured subsequent layer. Optionally, steps III) and IV) can be repeated with independently selected heat-curable silicone composition(s) for any additional layer(s) to form the 3D article. The first and second heat-curable silicone compositions may be the same as or different from one another.
