Abstract: This paper explores the way in which additively manufactured mandrels can streamline and simplify the production of tooling for composite part manufacturing, in particular for applications such as air, fluid, and energy management. The use of additive manufacturing (AM) to make mandrels streamlines the process when compared to traditional mandrel production processes, passing 3D data sets from design software to additive manufacturing platform to make the final mandrel. The paper will analyze how Gel Dispensing Printing (GDP) technology and the use of water-breakable materials can be combined to make wash-away, custom mandrels. Mandrels made using this combination of technologies and materials have the potential to disrupt the way composite parts and components are made. AM-produced mandrels are lighter than mandrels produced via legacy processes. AM also allows for much more complex designs than traditional machining methods. With AM, there are no constraints on the geometric shapes that can be produced, meaning that mandrels can be made with very intricate designs. This opens up a whole new range of possibilities for mandrel designs and functionality and means that they can be tailor-made to suit the specific needs of a particular application. It can result in faster production, and in addition, enables the production of composite parts that are more innovative than those produced using legacy processes.
