1. A method for building a three dimensional green compact comprising:
printing a mask pattern on a building surface with solidifiable material, the solidifiable material comprising photocurable polymer or thermal ink;
forming a layer by spreading powder material on the mask pattern;
compacting the layer; and
repeating the printing, forming and compacting until the three dimensional green compact is completed.
