Abstract
A method for developing a production process where a component is built up layer by layer by melting on powder material using a radiation source, and the melted-on powder material is subsequently solidified; in a first phase of the method, material-specific properties of a material being ascertained as a function of process parameters in a multiscale, physically based simulation chain independently of a component geometry; and, in a second phase of the method, taking into account the process parameters and the material-specific properties, an additive build-up of the component using this material being simulated which ensures minimal distortions and internal stresses. Also described is an installation for the generative production of components that includes a processing unit that is adapted for implementing a method for developing a production process.
