Claim:
1. A method for fabricating a porous structure with a machine, the method comprising the steps of: creating a model of said porous structure to be fabricated by said machine, wherein said model defines a strut of said porous structure comprising a first node, a second node, and a body between said first node and said second node; assigning a local coordinate system to said strut, said local coordinate system different from a machine coordinate system that defines a build plane of said machine; correcting a directional discrepancy of said machine by modifying a dimension of said strut in a direction perpendicular to said build plane, wherein said modifying step does not affect any changes to locations of said first node and said second node and comprises the steps of: fabricating, by the machine, the porous structure according to the model having the modified strut by exposing fusible material to an energy source.
