Method for Determining Building Instructions for an Additive Manufacturing Method, Method for Generating a Database with Correction Measures for Controlling the Process of an Additive Manufacturing Method

A method for determining building specifications describing process control for the additive manufacturing of a building structure on the basis of a simulation of the manufacture of the building structure, the method comprising:

• accessing a manufacturing data set for the building structure, the manufacturing data set describing the building structure in layers to be manufactured;
• calculating a global heat development in already manufactured layers of the building structure based at least in part on a building history of the building structure and heat input by an energy beam;
• determining a local heat development in a vicinity of the heat input by the energy beam;
• determining the process control based at least in part on the global heat development and the local heat development;
• loading correction measures of the process control from a database based at least in part on the global heat development and the local heat development;
• and
• assigning the correction measures locally to individual vectors of a tool path of the energy beam;
• wherein
• at least one mass integral is calculated for individual vectors of the tool path;
• and
• correction measures are determined on the basis of a comparison of the calculated mass integral with mass integrals stored in the database.
