Abstract
This work examines methods to create variable height layers using Wire Arc Additive Manufacturing (WAAM), a metal additive manufacturing process popular for its high deposition rate. We will examine how the torch speed can be used to control the height of the bead along each layer of a thin-walled part. Using this technique we are able to manufacture a part with an overhang that would traditionally only be possible using support material or geometric decomposition techniques. We then examine how the width of these parts changes as a function of the torch speed and feed rate of the welder. Using this relationship, we attempt to control the height and width of a thin-walled part independently. We then amend existing overlapping bead models to create angled layers for parts with widths larger than a single bead.
