UV curing technology with its advantages like, e.g. very fast curing or high scratch resistance of the coatings, is increasingly used in complex 3D applications as well. In order to achieve a consistent curing quality for the products, UV irradiation should be distributed as homogenously as possible across the 3d workpiece surface. In the industry there is a strong demand for helpful tools for the planning and optimisation of 3D curing processes. This paper presents a new simulation applications, developed in collaboration with a German automotive manufacturer. It allows the modelling of 3D UV curing processes, i.e. calculation of irradiance and dose, for arbitrarily shaped 3D objects with respect to lamp positioning, number of lamps needed, power output, lamp motions, conveyer speed, etc. The application has already been successfully used for supporting the planning of automotive UV curing processes.
