Abstract
A dam element for the damming of a structure element within a vehicle includes a support element and an expandable element. The support element consists of at least one printed strand of a first material, where the first material is in a solid physical state at least up to a temperature of from 120° C. to 200° C., and the expandable element consists of at least one printed strand of a second material, where the second material is expandable at a temperature between 120° C. and 200° C. The dam element here has, at a point of greatest thickness, measured perpendicularly to a plane of the dam element, at least two, and at most ten, mutually superposed layers.
Claims15
A dam element for the damming of a structure element within a vehicle, where the dam element comprises
- a support element consisting of at least one printed strand of a first material, where the first material is in a solid physical state at least up to a temperature of from 120° C. to 200° C.,
- an expandable element consisting of at least one printed strand of a second material, where the second material is expandable at a temperature between 120° C. and 200° C.,
- where the dam element has, at a point of greatest thickness, measured perpendicularly to a plane of the dam element, at least two, and at most ten, mutually superposed layers.
A process for the production of a dam element with a support element and with an expandable element for the use within a structure element of a vehicle, where the process comprises the steps of:
- provision of a bed element;
- printing of at least one strand made of a first material for the formation of a support element, where the first material is in a solid physical state at least up to a temperature of from 120° C. to 200° C.;
- printing of at least one strand made of a second material for the formation of an expandable element, where the second material is expandable at a temperature of from 120° C. to 200° C.;
- and
- removal of the dam element from the bed element;
- where the strands are printed in a manner such that the dam element has, at a point of greatest thickness, measured perpendicularly to a plane of the dam element, at least two, and at most ten, mutually superposed layers.
