Abstract
A material for three-dimensional printing including at least one of a functionalized silicone polymer, a functionalized silica particle, or a combination thereof; wherein the functionalized silicone polymer is functionalized with a member of the group consisting of a carboxylic acid, an amine, and combinations thereof; and wherein the functionalized silica particle is functionalized with a member of the group consisting of a carboxylic acid, an amine, and combinations thereof. A process for preparing the three-dimensional printing material. A process for three-dimensional printing use of the material.
Claims24
A material for three-dimensional printing comprising:
- a dry three-dimensional printing material comprising a functionalized silicone polymer and a functionalized silica particle;
- wherein the functionalized silicone polymer is functionalized with a member of the group consisting of a carboxylic acid, an amine, and combinations thereof;
- and
- wherein the functionalized silica particle is functionalized with a member of the group consisting of a carboxylic acid, an amine, and combinations thereof;
- wherein the dry three-dimensional printing material has a hardness determined by the selection of concentration of carboxylic acid, concentration of amine, ratio of carboxylic acid to amine, or a combination thereof, on the functionalized silicone polymers or functionalized silica particles.
A process for preparing a material for three-dimensional printing comprising:
- providing a silicone polymer and a silica particle;
- and
- functionalizing the silicone polymer with a member of the group consisting of a carboxylic acid, an amine, or a combination thereof;
- functionalizing the silica particle with a member of the group consisting of a carboxylic acid, an amine, or a combination thereof;
- to provide a dry three-dimensional printing material, wherein the dry three-dimensional printing material has a hardness determined by the selection of concentration of carboxylic acid, concentration of amine, ratio of carboxylic acid to amine, or a combination thereof, on the functionalized silicone polymers and functionalized silica particles.
A method for three-dimensional printing comprising:
- providing a dry three-dimensional printing material comprising a functionalized silicone polymer and a functionalized silica particle;
