Abstract

A method for manufacturing a three dimensional object includes steps of: providing a digital description of the object as a set of voxels; sequentially creating an actual set of voxels corresponding to the digital set of voxels. At least one voxel comprises a polymer derived from: polyol and an ionic monomer. The calculated charge density of the resulting polymer is 0.01 to 0.7 mEq/g. A three-dimensional object having at least one voxel. The at least one voxel including a polymer derived from: a polyol and an ionic monomer, and the calculated charge density of the resulting polymer is 0.01 to 0.7 mEq/g.
