Abstract Scope |
Direct ink write (DIW) is a commonly used technique in polymer additive manufacturing, where filaments of material are deposited to build 3D structures. The development of desktop robotic arms have enabled the capability for conformal and support free printing within the DIW field; However, the research on the effects of printing with a robotic arm vs a gantry system on the material properties is limited. We investigated the effects of DIW with a robotic arm on the printability and material properties of an anisotropic material as compared to a gantry system. Using a carbon fiber epoxy composite ink, samples were mechanically tested, 3D scanned to investigate geometrical accuracies, and CT scanned to analyze fiber alignment to elucidate the role of nozzle orientation, kinematics, and gravity on the material properties. This research will provide insight into deposition technique effects on material properties, providing a better understanding of printing onto complex surfaces. |
