Modeling of effect of powder spreading on green body dimensional accuracy in additive manufacturing by binder jetting

It is shown that Bullet Physics Engine can be used for Discrete Element modeling of powder spreading during additive manufacturing by binder jetting. It is known that, due to technological restrictions, the thickness of deposited layers during binder jetting should not exceed several powder particle...
