Abstract Scope |
Cohesion between binder droplets is a foundational part of printing binder jetted parts. If not carefully controlled, balling defects may occur that weaken the mechanical properties of the final part. Previous work has found that controlled prewetting allows for larger droplet spacing and decreased balling. This research expands this study to multi-line printing. By optically analyzing multi-line prints, it was found that the number of adjacent lines and controlled prewetting increase print cohesion and prevent balling where it occurs in single-line printing. Understanding these effects on print quality enlarges the printing window for binder jetting while ensuring high quality parts. |
