Abstract: The field of rapid prototyping has demonstrated elements of production to become rapid manufacturing (RM). Key elements of this transition involve a distinct requirement for a consistent mechanical property evaluation technique to be used as a baseline for direct part fabrication. This research portrays proven techniques developed by industry to evaluate additive manufacturing (AM) for a variety of applications. Data are generated using the techniques provided and are applied to the generation of statistical analysis assessments. These data are compiled and used by design engineers to assess the technical feasibility of RM for integrated designs. Fused deposition modelling is gaining ground for AM applications. The research provided offers a path for technical specification development using case examples.
