VERFAHREN ZUR HERSTELLUNG EINES ADDITIV GEFERTIGTEN PRODUKTS AUS EINEM MINERALISCHEN AUSGANGSMATERIAL MITTELS DIREKTER LASERVERSINTERUNG SOWIE EIN NACH DIESEM VERFAHREN HERGESTELLTES LEICHTBAUTEIL
The invention relates to a method for utilizing mineral materials for additive manufacturing that can be implemented more quickly, more economically and with greater technical simplicity, in comparison with common additive manufacturing, by virtue of controlled expansion in the sintering process by means of a laser source. The entire production process is free of organic materials and allows previously unfeasible end uses in the fields of acoustic insulation, thermal insulation, fire protection, filtration, design objects and lightweight components to be realized. In particular, the invention relates to a method for producing a product by means of 3-D printing or additive manufacturing, wherein an open-pore lightweight part is constructed layer-by-layer, without the use of organic binders or other organic auxiliary agents, from a pulverous mineral starting raw substance of natural origin, which raw substance is obtained without chemical alteration of the solid constituents of the natural material, and wherein, beginning with the second layer, the most recently applied layer is bonded to the surface of the existing body of the lightweight part by means of immediately subsequently performed direct selective laser sintering.
