Abstract
An improved process for making a structure using three dimensional printing techniques is disclosed. Briefly stated, the method can be summarized by the following steps: A first type of powder material is deposited in a defined area to form a first layer. Next, a binder material is applied to certain regions of the first type of powder to define a portion of the structure to be formed. And finally, a portion of the unbound powder is removed using a technique such as vacuuming. The foregoing steps are repeated a sufficient number of times to create the desired shape of the structure as defined by the regions held by the binder material.
