A method of forming a three-dimensional (3D) article is disclosed. The method comprises I) printing a first thermoplastic silicone composition with a 3D printer to form an at least partially solidified layer. The method further comprises II) printing a second thermoplastic silicone composition on the at least partially solidified layer with the 3D printer to form a subsequent at least partially solidified layer. Optionally, step II) may be repeated with independently selected thermoplastic silicone composition(s) for any additional layer(s) to form the 3D article. The first and second thermoplastic silicone compositions are the same as or different from one another.

3D printing method utilizing thermoplastic 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.
