Abstract
The present invention relates to free-form structures made by additive manufacturing, and methods for the manufacture thereof. The rigid free-form structures comprise a lattice structure which is impregnated by a polymeric or other material. The rigid free-form structures may be used in wound treatment, e.g., as a facial mask.
Claims17
A facial mask, comprising:
- a free-form structure configured to apply substantially equal pressure over an area of a user's face, wherein the free-form structure comprises:
- a lattice structure comprising a varied pattern of unit cells configured to provide local variations in flexibility in the lattice structure, wherein the local variations in flexibility provide complementarity with the area of the user's face, thereby creating a zone of uniform contact and pressure, and
- a coating material in which the lattice structure is at least partially embedded.
A method for manufacturing a facial mask, comprising:
- providing a three dimensional representation of an area of a user's face;
- designing a free-form structure based on the three dimensional representation of the area of the user's face, wherein the free-form structure is configured to apply substantially equal pressure to the area of the user's face, and comprises:
- a lattice structure comprising a varied pattern of unit cells configured to provide local variations in flexibility in the lattice structure, wherein the local variations in flexibility provide complementarity with the area of the user's face, thereby creating a zone of uniform contact and pressure, and
- a coating material in which the lattice structure is at least partially embedded;
- and
- manufacturing the lattice structure by additive manufacturing and providing the coating material on the lattice structure.
