Abstract Scope |
Print quality and print speed limit the increased use of Binder Jetting in industry. Further understanding of binder/powder interactions will dramatically improve the quality and speed of the development process. With increased understanding, simple procedures or tests could predict print saturation levels, optimize green part strength, decrease print time, and improve dimensional accuracy. Current methods of characterization of the interaction overlook the crucial interactions between printing parameters including drop velocity, droplet spacing, line spacing, and inter-arrival time. Previous work shows the impact of droplet velocity, spacing, and inter arrival times on single printed lines. This presentation will compare these results to studies on single and multi-layer parts. Printed parts are characterized by their mass and optical inspection. The relationships between parameters that form single printed lines are compared to limits to create single and multi-layer parts. |
