Abstract Scope |
This study investigates the feasibility of 3D printing multi-material layered structures via binder jetting methodologies. A manual binder jet printer that enables printing with two different materials simultaneously, and with a magnetic field, was designed and built. Samples were printed from ball-milled powder. Testing was done to determine acceptable layer thickness, dry time, and binder saturation for samples with sufficient green strength. After printing, samples were sintered in a purged argon atmosphere to densify the parts. Microstructure was investigated using SEM. Element distribution at layer interfaces and throughout layers was analyzed using EDS and part density was determined by image analysis of optical micrographs. Additionally, phase transformation and Curie temperatures were identified using DSC and magnetic properties were measured using VSM. It was found that layered printing provides the opportunity to create samples with multiple compositions that show phase transformations within two distinct temperature ranges. |
