Abstract
The invention relates to a method for manufacturing a three-dimensional componentby means of an additive construction method in which the componentis constructed by solidifying construction materialthat can be solidified using radiation, especially a selective laser melting method or a selective laser sintering method, in which the componentis produced by successively solidifying construction materialthat can be solidified using the impact of radiationby melting or sintering, comprising the following features: providing an additive construction apparatus, especially an SLM apparatus or an SLS apparatus, comprising a process chamber, a construction platformfor carrying the construction material, and a radiation source arranged above the construction platformfor generating a point-type or linear energy input for creating a melting or sintering section in the construction material, providing a sensor apparatusfor selective detection of created melting or sintering sections and for the generation of sensor values therefrom for characterizing the melting or sintering sections, and storage of said sensor values together with coordinate values localizing the sensor values in the component, determination of load and flux information in the componentmanufactured or to be manufactured by means of a calculation or measuring method for determining critical load areas in the componentmanufactured or to be manufactured, spatial correlation of the sensor values determined for the evaluation of the component quality together with the coordinate values localizing said values with coordinates of the load and flux information, and assessment of the componentfinished or to be finished, such that componentsfor which sensor values negatively impacting the component quality are determined in the range of critical or highly loaded sections of the load and flux information are classified as componentsnot corresponding to the requested component quality, and componentsfor which sensor values negatively impacting the component quality are determined with sufficient distance from critical or highly loaded sections of the load and flux information are classified as componentscorresponding to the requested component quality.
