In an effort to make the aerospace industry more sustainable, GKN Aerospace is heavily investing both time and money into additive manufacturing technologies. A challenging aspect with additive manufacturing is finding a set of process parameters that produces high quality parts and components to a standard that the aerospace industry demands. To aid the process development, turning to simulations is a great alternative and with the prospect of adding to the tools available, the work of this thesis has been focused on developing a mathematical model of the cross sectional deposition geometry. Through a literature study, an initial approach to developing such a model, as well as gaps in knowledge was established. Validation data was gathered by laser scanning additively manufactured builds. A model based on a fourth degree polynomial was developed. The fourth degree polynomial model was validated with the laser scan data using the mean squared error value and coefficient of determination as a quantifiable method of determining the goodness of fit. It was found to be an improvement over the common parabolic model found in the literature based on a second degree polynomial. The improved model manages to capture a wide variety of contact angles and the overlap region better follows the smooth transition between beads.
