The UV curing of coatings on large, three-dimensional (3D) objects is the next frontier in industrial UV processing. These include objects ranging from automobile bodies and parts to aircraft parts and bathtubs. In most cases, process development for 3D curing can be extremely time consuming, especially if the object to be cured is large and is complicated (i.e., it contains many surface features). In some cases, proper process development for large complicated objects can take days, and can result in high development costs in the form of scrap parts and wasted coating. In order to facilitate process development on 3D objects, Fusion UV Systems has developed a computer simulation, that can be used to optimize the 3D curing of coatings on large 3D objects. UVCADTM includes an accurate model of the optical performance of the UV lamp and can simulate systems with up to 100 lamps. Simulation inputs include chemistry data (process windows, absorption coefficients, and indices of refraction), the mechanical design of the curing chamber, and a CAD description of the object to be cured. We will discuss the design of the simulation program and will present the results of various test cases.
