Title: METHOD AND APPARATUS FOR FORMING LAYERS OF PARTICLES FOR USE IN ADDITIVE MANUFACTURING
Abstract:
A method and an apparatus for forming a particle layer are provided. The layering method includes injecting particles in an injection zone defined at a gas-liquid interface between a carrier liquid and an ambient gas, and controlling a flow of the carrier liquid along the gas-liquid interface to carry the particles downstream along a particle flow path from the injection zone to a layer formation zone. The method also includes accumulating the particles in the layer formation zone to gradually form the particle layer on the gas-liquid interface, and withdrawing the particle layer from the layer formation zone. The particle layer formed by the layering method and apparatus can be used to fabricate a three-dimensional object by additive manufacturing.
