Abstract
Techniques are disclosed for converting a stereolithographic model into an STL data file that defines logically related components and subcomponents of an object. A user can categorize elements of an object to form logically related components and subcomponents of the object. Each element is represented by a triangle. All triangles representing each of these components and subcomponents are then reordered and listed sequentially within the STL. Each list is delimited at the beginning and end by two hidden triangles, one or both of which store unique identification values that are associated with the respective individual components. Additionally, a reference table can be added to the STL. The reference table includes instructions, operations or other information that is specifically associated with each component and subcomponent using the unique identification values. These instructions and operations enable users to have better control over 3D print quality than is possible using existing techniques.
