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.

First claim

What is claimed is:

wherein at least one voxel comprises a polymer derived from:
a polyol, wherein the polyol has a number average molecular weight of at least 2,000 g/mol; and
an ionic monomer,
wherein the calculated charge density of the resulting polymer is 0.01 to 0.7 mEq/g; and,

where the polymer comprises a benefit agent which is a perfume oil encapsulated in a shell.

2. The three-dimensional object according to claim 1 , wherein the polyol is selected from the group consisting of polyethylene glycol, polyethylene oxide, poly(ethylene glycol-co-lactic acid), poly(ethylene glycol-co-glycolic acid), poly(ethylene glycol-co-poly(lactic acid-co-glycolic acid), poly(ethylene glycol-co-propylene glycol), poly(ethylene oxide-block-propylene oxide-block-ethylene oxide), poly(propylene oxide-block-ethylene glycol-block-propylene glycol), and poly(ethylene glycol-co-caprolactone).
