A method for forming a three dimensional object

摘要

A method for forming a three dimensional object including the steps of: depositing successive layers of powder onto a surface; selectively bonding the powder to form a three dimensional object; surrounding the three dimensional object with a particulate material; and urging the particulate matter towards the object to exert a pressure directly or indirectly thereon and applying heat directly or indirectly to the object such that the object is densified.
