Multi-formulation Printing (MFP)
Controlling the performance of multi-material 3D printed structures requires fundamental understanding of the role of dual nozzle printing, multi-material composition, and multi-material interfaces on dynamic combustion and mechanical properties. Such effects are explored through experimentation and modeling.
Dissimilar Material Printing (DMP)
Dissimilar material printing is considered an extreme form of multi-material printing due to the integration of thermoplastic and viscous composite mixtures within one structure. The combination of Fused Filament Fabrication with Direct Write techniques presents the challenge of processing different material properties, the coordination of different printing parameters, and poor interfacial adhesion. Methods to overcome such challenges are being explored.
Anomaly Detection in Extrusion-based Additive Manufacturing
Qualifying a 3D printed part is challenging when extrusion-based 3D printing process are error prone. By integrating sensors onto 3D printers and leveraging techniques such as statistical process control, anomalies (i.e. defects) within a printed structure can be detected, which will assist operators in assessing the quality of the product. The goal is to develop quantitative tools to assess the quality and predict the performance of a 3D printed part.
