Method for manufacturing a compact component comprising a shell and a grid structure made of a shell material the grid structure being located inside the shell , and further a core structure that fills the interior of the shell and is made of a core material, wherein the method comprises the steps of: (a) generative construction of at least one layer of the shell and of the grid structure that extends along a sectional plane of the component , which layer consists of a particulate material of the shell material or at least one reactant thereof, by means of a beam melting method, comprising the steps of: (a1) applying a layer of the particulate material of the shell material or of at least one reactant thereof, and (a2) melting, sintering and/or solidifying the material to produce a layer of the shell and of the grid structure by irradiating with laser light according to a contour of the component along the sectional plane of the component and (b) melting, sintering and/or solidifying a nanoparticulate material of the core material or at least one reactant thereof which is located in the interior of the at least one layer of the shell , to form the core structure of the component , wherein initially the shell and the grid structure are constructed generatively layer-by-layer by repetitions of the steps (a1) and (a2) up to a predetermined component height of the component, then (b1) the interior of the shell is filled with the nanoparticulate material of the core material or of at least one reactant thereof, or the interior remains filled with the material of the core material, which is identical to the material of the shell material, and (b2) the core structure of the component is formed by melting, sintering and/or solidification; or the shell and the grid structure and the core structure are manufactured synchronously layer-by-layer, wherein the steps (a) and (b) are repeated until a predetermined component height of the component is reached. (a) generative construction of at least one layer of the shell and of the grid structure that extends along a sectional plane of the component , which layer consists of a particulate material of the shell material or at least one reactant thereof, by means of a beam melting method, comprising the steps of: (a1) applying a layer of the particulate material of the shell material or of at least one reactant thereof, and (a2) melting, sintering and/or solidifying the material to produce a layer of the shell and of the grid structure by irradiating with laser light according to a contour of the component along the sectional plane of the component and (a1) applying a layer of the particulate material of the shell material or of at least one reactant thereof, and (a2) melting, sintering and/or solidifying the material to produce a layer of the shell and of the grid structure by irradiating with laser light according to a contour of the component along the sectional plane of the component (b) melting, sintering and/or solidifying a nanoparticulate material of the core material or at least one reactant thereof which is located in the interior of the at least one layer of the shell , to form the core structure of the component , <EOS>
