Though the technology has progressed significantly since its inception, the details of powder particle distribution and spreading are complicated and not completely understood. However, distribution and spreading affects the powder packing and therefore sintering behavior [1]. There have been efforts to model the physics of powder spreading, mostly for the purposes of laser melting techniques, but every mathematical model necessarily makes some idealistic assumptions [2]. In practice, the distribution of powder particle sizes in an actual binder-jet printed part have not been directly examined.
