METHOD AND SYSTEM FOR ADDITIVE MANUFACTURING WITH POWDER MATERIAL

Abstract:

An additive manufacturing system for building a green block including a three dimensional green usable model includes a printing station, a powder delivery station, a compacting station and a stage. The printing station prints a pattern on a building tray by selectively depositing a solidifiable non-powder material that forms a partition by tracing a perimeter of a usable model to be printed per layer and tracing a plurality of discrete sections of a support area around the usable model. The powder delivery station applies a layer of powder material over the pattern. The compacting station compacts per layer of powder material and includes a die for receiving the layer. The stage repeatedly advances the building tray to each of the printing station, the powder delivery station and the compacting station to build a plurality of layers that together form the green block.
