1. A computer readable medium having instructions stored thereon which, when executed by a processor, cause the processor to perform the steps of:
- forming a plurality of 3-D fragments of an object having at least one set of alignment marks;
locating at least two fragments having a corresponding set of alignment marks;
aligning said at least two fragments with respect to an arbitrary coordinate system using said corresponding set of alignment marks in the respective fragments.

placing a first point of a first fragment at an origin of said coordinate system;
placing a second point of said first fragment at an axis of said coordinate system;
rotating said third point of said first fragment about said axis of said coordinate system until said third point is in a plane corresponding to said axis and another axis in said coordinate system;
placing a fourth point of a second fragment corresponding to said first point at said origin of said coordinate system;
placing a fifth point of said second fragment corresponding to said second point at said axis of said coordinate system; and
rotating said sixth point of said second fragment corresponding to said third point said axis of said coordinate system until said sixth point is in said plane.

5. A method of aligning three dimensional (3-D) fragments comprising:
-
forming a plurality of 3-D fragments of an object having at least one set of alignment marks;
locating at least two fragments having a corresponding set of alignment marks, wherein said set of alignment marks is a set of three points, each of said points is unique relative to another;
aligning said at least two fragments with respect to an arbitrary coordinate system using said corresponding set of alignment marks in the respective fragments, wherein said step of aligning further comprises;
placing a first fragment at an origin of said coordinate system;
rotating said third point of said first fragment about said axis of said coordinate system until said third point is in a plane corresponding to said axis and another axis in said coordinate system;
placing a fourth point of a second fragment corresponding to said first point at said origin of said coordinate system;
placing a fifth point of said second fragment corresponding to said second point at said axis of said coordinate system; and
rotating said sixth point of said axis of said coordinate system until said sixth point is in said plane.
