- Rosin Based Composites for Additive ManufacturingPublication . Sousa, Dora; Biscaia, Sara; Viana, Tânia; Gaspar, Miguel Belbut; Mahendra, Vidhura; Mohan, Saeed D.; Mateus, Artur; Mitchell, GeoffreyRosins are the non-volatile exudates of pine resins with hydrophobic characteristics that are widely used as a precursor for many industrial applications. In this paper we discuss the nature, process and its applications as a matrix for a composite material for additive manufacturing. The composite material has been tailored to chemical and mechanical properties with respect to their applications.
- Tools to define and evaluate morphology mapping, a route to complex structures using direct digital manufacturingPublication . Pinheiro, João; Abdulghani Oliveira da Silva, Saba; Pascoal-Faria, Paula; Sousa, Dora; Carreira, Pedro; Viana, Tânia; Kamma-Lorger, Christina S.; Mitchell, GeoffreyDirect Digital Manufacturing is a new set of technologies which allow objects to be printed directly from a digital definition. Such technologies allow us to manufacture any self-supporting shape, but simply replicating shape is not sufficient for the production of many parts especially those with specific function. We need to be able to generate complex multiscale structures similar to those we observe in nature. Direct digital manufacturing can be seen as method for achieving this, as we can deposit materials with different compositions and different structures in selected volumes and thereby generate a complex structure. This manuscript addresses the challenges of achieving this concept and the tools needed to characterize the parts produced and the variation in the composition and structure. We conclude by discussing how we might design such complex parts.
