Abstract
The invention relates to a method for the manufacture of light open porous components of metal, metal alloys, plastic or ceramic of any geometry. Here, the component is produced through casting liquid material into a casting device (01), wherein a core stack (04) is mounted, cast and removed in a casting mold (03). The core stack (04) here is designed as a regular multi-dimensional core lattice (09) with defined core lattice planes (12), where each core lattice plane (12) is constructed of individual regular core bodies (10).
Claims15
A method for the manufacture of light open porous components of metal, metal alloys, plastic or ceramic of any geometry, wherein the component is manufactured through pouring liquid material into a casting device (01), comprising:
- mounting a core stack (04) in a casting mold (03),
- casting the liquid material into the casting mold to form a composite article and
- removing the core stack (04) from the composite article to obtain a light open porous component, wherein the core stack (04) is designed as regular multi-dimensional core lattice (09) with defined core lattice planes (12), where each core lattice plane (12) is preconstructed of individual regular core bodies (10) joined through ligaments and the individual core lattice planes (12) are joined with one another in two or several layers, wherein the individual layers are displaced to each other by a lattice offset to form the core stack (04) so that the core bodies (10) previously slicked or provided with adhesive of the individual planes (12) contact one another by means of binder or adhesive bridges and the material used for manufacturing the core lattice planes (12) is an inorganic powder or sand.
