Abstract Scope |
Binder Jetting (BJ) is an additive manufacturing process that enables production of complex, high-resolution parts. Understanding binder-powder interaction during the printing process is essential to optimizing the printing process, selecting appropriate process parameters, and improving final part quality. This work presents findings from high-speed imaging of the BJ process using synchrotron X-rays. During testing, five key print process parameters were adjusted including: powder material, droplet spacing, line number, powder bed packing fraction, and powder bed moisture levels. High-speed X-ray footage acquired during printing captures powder ejection above the powder bed surface and powder disturbance below the powder bed surface due to droplet impact. Interaction behavior extracted from the X-ray footage was used to help identify significant print process parameters that impact the observed binder-powder interactions and help develop understanding of the underlying physical mechanisms of binder-powder interaction during the BJ printing process. |
