METHOD FOR DETERMINING BUILDING REGULATIONS FOR AN ADDITIVE PRODUCTION METHOD, METHOD FOR CREATING A DATABASE WITH CORRECTIVE MEASURES FOR THE MANAGEMENT OF AN ADDITIVES PRODUCTION PROCESS, STORAGE FORMAT FOR BUILDING INSTRUCTIONS AND A COMPUTER PROGRAM PRODUCT

摘要

The invention relates to a method for determining construction instructions describing a process control which can be used for an additive manufacturing method in a system 11 for additive manufacturing. A production data record PAR is generated in order to produce the building structure in layers 25. Global heat development and local heat development are taken into account. According to the invention, correction parameters are loaded from a database F as a function of the global heat development, and these can be locally assigned to individual vectors of a tool path as corrective measures of the process control. The tool path defines the path that the energy beam 17 takes on the surface of the powder bed 13. Furthermore, the invention relates to a method for determining correction parameters PAR for a process control in an additive manufacturing plant 11. This is achieved according to the invention in that the local heat development in the vicinity of the heat input of the energy beam 17 is calculated. The corrective measures are derived from the heat development and stored in a database F. The advantage of using both methods is that a precise simulation is only necessary on a mesoscale scale and can also be carried out in advance of preparation for manufacturing the component 19. If the geometry of the component 19 is known, then only a macro-scale simulation has to be carried out to define the global heat development. This significantly reduces the computational complexity of the simulation, so that the modified process parameters PAR sub 1 /sub can be found easily. The invention also relates to a storage format for the modified data and computer program products for storing the programs.
