Abstract
An additively manufactured gasket comprising a main body, comprising an outer wall, an inner wall opposite the outer wall, and a hollow chamber defined by the inner wall. The additively manufactured gasket further comprising an uncured powder core arranged in the hollow chamber.
Claims20
An additively manufactured gasket, comprising:
- a main body, comprising:
- an outer wall,
- an inner wall opposite the outer wall, and
- a hollow chamber defined by the inner wall;
- and
- an uncured powder core being trapped within the hollow chamber during additive manufacturing and configured to elastically deform to accommodate dimensional tolerances, the uncured powder core being made of a thermoplastic urethane that remains in a raw and unprocessed state.

A vehicle, comprising:
- a vehicle component, comprising:
- an additively manufactured gasket, comprising:
- a main body made of a thermoplastic urethane material, comprising:
- an outer wall defining a height of the main body,
- an inner wall opposite the outer wall defining a gap of the main body,
- a thickness between the outer wall and the inner wall, and
- a hollow chamber defined by the inner wall, the hollow chamber having gasket chamber volume,
- one or more intermittent retention features, comprising:
- a first feature extending from the outer wall, and
- a second feature spaced from the first feature and extending from the outer wall;
- and
- an uncured powder core made of the thermoplastic urethane material, the uncured powder core being trapped within the hollow chamber during additive manufacturing remaining in a raw and unprocessed state, the uncured powder core being configured to elastically deform to accommodate dimensional tolerances and having a powder volume that is substantially similar to the gasket chamber volume.
