Abstract
A method for producing a structural component having a foam structure formed by foaming a foamable material, includes the following steps: additively building a receiving component that reproduces the outer geometry of the structural component to be produced at least in some sections, in particular completely, and having a receiving space for receiving foamable material; introducing at least one foamable material into the receiving space of the receiving component; and carrying out at least one measure for foaming the foamable material introduced into the receiving space of the receiving component so as to form the foam structure.
Claims15
A method for producing a structural component which comprises a foam structure formed by foaming of a foamable material, the method comprising the steps of:
- additively building up a receiving component which replicates, at least in certain sections, an external geometry of the structural component to be produced and which comprises a receiving space for receiving foamable material;
- introducing at least one foamable material into the receiving space of the receiving component, wherein at least one support structure permits a discharge of heat and prevents expansion of the receiving component;
- implementing at least one measure for foaming the foamable material that has been introduced into the receiving space of the receiving component, so as to form the foam structure;
- and
- using a surface-activation measure to create a connection between the foam structure and the receiving component, wherein
- the at least one measure for foaming the at least one foamable material is implemented in a tool which comprises a temperature-controllable tool interior space, and
- the at least one support structure negatively replicates, at least in certain sections, the external geometry of the receiving component and is introduced into the tool interior space.
