| Abstract Scope |
Binder Jetting (BJ) is an additive manufacturing process that creates parts in a layer-wise process from a powder feedstock using inkjet droplets of binder. Binder Jetting shows promise as an industrial process. However, limited understanding of printing process parameters leads to defects in the printed parts and may limit build rates. In this study, lines were printed with a range of print parameters, extracted using an adhesive film, and imaged to quantify line size and quality. Print parameters included droplet spacing, inter-arrival time, amount of moisture in the powder bed, droplet size, and droplet velocity. Results from this study show that pre-treating the bed with moisture combined with low velocity droplets increases the range of print parameters that result in successful line formation and the potential for faster build rates. |
