Abstract
Recent developments in rapid prototyping and additive manufacturing (AM) processes have focused on, among other topics, incorporating reinforcing fibres to structures being built in a layer by layer fashion. This focus has enabled such processes to progress from prototyping to actual manufacturing with parts suitable to be used in high-load and realistic application conditions. This thesis introduces a set of robust design principles for the AM of fiber-reinforced structures with the aim to drive innovation in this field and lead to the creation of novel technologies. The principles were developed after a comprehensive survey of the latest academic literature and patents to identify fundamental insights that are important for awareness of designers and engineers in the field. Twenty three unique principles are identified, complete with descriptions and references for each principle. These principles are categorised in a matrix of established composite concepts and AM sub-functions. Finally, a design case study is discussed to highlight the utility of the principles in a real life design challenge.
