The interaction of droplets with powder is the key set of phenomena that determine many aspects of Three Dimensional Printing (3DP) including dimensional control and surface finish of the printed part. In the creation of structural ceramic parts by 3D printing, fine powders on the order of 1 gm in size must be used. These powders are deposited as slurry and then dried to form a fairly hard cohesive powder bed. The purpose of this work is to understand the interaction of droplets with such cohesive powder beds, the integration of droplets with previously printed droplets, and to explore print styles which improve the dimensional control and surface finish. Single drop primitives were printed and removed from the powder bed and found to resemble discs with a flat top and a rounded bottom with a typical diameter of 180 Vtm and a thickness of 40 [tm. A number of different time domains are defined based on the interaction of droplets with cohesive powder beds. Critical times in defining these domains are: 1) the amount of time it takes for a droplet to splat and spread on the powder bed, 2) the amount of time it takes for the droplet to absorb into a powder bed
