Abstract
A polyol stiffening additive in a powder bed material for three-dimensional (3D) printing is disclosed herein. In an example, the 3D powder bed material includes an elastomeric build material and a polyol stiffening additive having 3 to 7 carbon atoms that is about 2 weight percent to about 20 weight percent of a total weight of the 3D powder bed material.
Claims14
A three-dimensional (3D) powder bed material that forms a 3D printed article, the 3D powder bed material consisting of:
- an elastomeric build material;
- and
- a polyol stiffening additive having from 3 to 7 carbon atoms, the polyol stiffening additive being present in an amount of from about 2 weight percent to about 20 weight percent of a total weight of the 3D powder bed material.
A method of making a three-dimensional (3D) printed article, the method comprising:
- applying a 3D powder bed material consisting of a mixture of an elastomeric build material and a polyol stiffening additive having from 3 to 7 carbon atoms to a fabrication bed;
- and
- fusing the 3D powder bed material to form a 3D printed article.
A three-dimensional (3D) printed article formed by:
- applying a 3D powder bed material consisting of a mixture of an elastomeric build material and a polyol stiffening additive having from 3 to 7 carbon atoms to a fabrication bed;
- selectively applying a fusing agent to the 3D powder bed material;
- and
- responsive to the selectively applying of the fusing agent to the 3D powder bed material, fusing the 3D powder bed material to form the 3D printed article.
