DEM Extensions: Electrically Driven Deposition of Polydisperse Particulate Powder Mixtures
- 1.6k Downloads
A key part of emerging advanced additive manufacturing methods is the deposition of specialized particulate mixtures of materials on substrates. For example, in many cases these materials are polydisperse powder mixtures whereby one set of particles is chosen with the objective to electrically, thermally, or mechanically functionalize the overall mixture material and another set of finer-scale particles serves as an interstitial filler/binder. Often, achieving controllable, precise deposition is difficult or impossible using mechanical means alone.
